Report on the commissioning of the boiler house in excel. Preparation of technical reports on commissioning works

What is NDP and why they are carried out

According to SNiP, commissioning is a set of activities that are carried out during the preparation for the implementation of integrated testing and individual testing of installed equipment. This includes checking, testing and adjusting equipment to achieve design parameters.

The performance of all these manipulations is usually carried out on a contractual basis by specialized organizations that have the necessary permits and a staff of qualified specialists. The necessary conditions for their activities at the site (industrial sanitation, labor safety) are organized by the customer, he also pays for commissioning at the expense of the general estimate for putting the facility into operation. All operations must be carried out by instructed and certified for each specific case by the personnel of the commissioning organization under the supervision of a responsible representative on the part of the customer.

There are two main stages in the commissioning activities:

Individual tests are actions that are designed to ensure the fulfillment of the requirements that are provided for by the technical specifications, standards and working documentation for testing units, machines and mechanisms. The purpose of individual tests is to prepare for complex testing in the presence of a working commission.
Complex tests are actions carried out after the acceptance of the mechanisms by the working commission, and directly the complex testing itself. At the same time, the interconnected joint operation of all installed equipment is checked at idle, then under load, after which the technological regime provided for by the project is reached.

Although this is not prescribed by law, in recent years, more and more often, the customer requires that a commissioning program be drawn up for testing work. This gives confidence that not a single nuance will be missed, and the operation of all systems will comply with approved standards and project documentation.

How is it compiled and what does the commissioning program include?

The commissioning program is a document that clearly describes the entire list of actions that will be carried out responsible organization. On the net, you can see discussions about whether it is worth including a commissioning methodology in the Program or whether it should be drawn up as a separate document. There are no clear requirements regarding this, so everything here depends on the agreements of the parties. A sample for each specific situation can be easily found on the Internet.

The program is drawn up and approved by a representative of the commissioning company and agreed by the customer, the signatures and seals of the parties are put in the header of the document. The following sections follow (as an example, let's take the preparation of a hotel heating system):

checking the correctness of installation, readiness and serviceability of equipment in visual mode (control devices, valves, filling the system with water), following the results, a defective list is compiled;
commissioning tests in operating conditions, balance experiments (setting optimal modes, testing valve control in manual and automatic modes, checking automation settings, identifying shortcomings and working out proposals for their elimination), the result is an act of individual tests;
comprehensive testing (72 hours of continuous operation for all main equipment, 24 hours for heating networks), its beginning is the time when all systems are started at maximum load.

Some companies document all activities related directly to the preparation and testing of devices in a separate document - the Commissioning Methodology, which comes as an addition to the Program. In the Program, they include more general things of an organizational nature. That is, there is an actual division of the entire complex of works into organizational, legal and technical components. However, the Methodology is often an integral part of the main body of the approved Program.

An integral part of the Program may be such additional documents:

passports of ventilation, heating and hot water supply systems, as well as individual nodes of their connection;
the procedure for preparing and subsequent commissioning with a list of all operations, their start and end times;
list of stationary and portable measuring instruments (pressure gauges, thermometers, etc.);
list of control and stop valves, equipment (pumps, valves, heat exchangers, filters);
list of control points and measurement protocol for each of them;
a list of parameters that require clarification and adjustment (humidity and air temperature, pressure in pipes, coolant flow rates);
a method for measuring heat losses by building structures (a special act is drawn up and a certificate is issued).

After the completion of all commissioning works, complex testing and regime tests, a commissioning report is drawn up with the relevant annexes (a list of mechanisms and equipment on which adjustment and testing was carried out).

The technical report of the involved specialized organization issues, as a rule, within one month.

Good afternoon, our design organization has completed designing commissioning and commissioning of the ventilation system at the research institute.

5. Results of the analysis of project documentation and quality control of installation work

Ventilation systems automation project (section AOV brand) and installation of automation systems completed

The analysis of the project documentation showed that the working drawings were made in accordance with the requirements of the current regulatory documents and the technical documentation of the equipment manufacturers.

The verification of the compliance of the installation of automation equipment with the project and the requirements of manufacturers did not reveal significant shortcomings and defects.

6. INDICATORS OF THE QUALITY OF THE OPERATION OF THE REGULATION LOOP AND THE METHOD OF THEIR CALCULATION

6.1. Mathematical model of the control loop

To calculate the performance indicators of the control loops, a mathematical model of the control loop was adopted in the form of a closed automatic control system (CSA) with regulation according to the Polzunov-Watt principle. The block diagram of the ACS is shown in Fig. 6.1, where the following designations are accepted:

Δу - adjustable parameter;

yset - set value of the controlled parameter (setpoint);

u - control action;

g - disturbing action;

KR - amplification factor;

Ti - constant of integration;

Td is a constant of differentiation.

The choice of the type of control law is made on the basis of the analysis of the characteristics of the automation object (clause 3), design features sensors and actuators (clause 4), as well as experience in setting up regulators of similar systems.

The following was chosen as the regulation law:

· isodromic law (PI-regulation), while Td=0;

The isodromic law was used for the following control loops:

air temperature behind air coolers;

supply air temperature;

temperature of the return heat carrier after the air heater of the first heating;

humidity when the systems are operating in the WINTER/SUMMER mode.

6.2. The quality indicators of the control loop and

transitional process. Evaluation of the work of the control loop was carried out on the basis of the analysis of the characteristics of the transient process. Transient processes in ventilation and air conditioning systems equipped with automatic control systems are characterized by the following indicators (see Fig. 6.2):

1) static control error is defined as the maximum deviation of the value of the controlled parameter from its set value after the end of the transient process;

2) dynamic error is defined as the maximum deviation of the controlled parameter from the set value observed during the transient process. With aperiodic control processes, there is only one maximum and one value of the dynamic error. With oscillatory transients, several maxima and, consequently, the values of the dynamic error are observed: (see Fig. 6.2);

3) the degree of attenuation of the transient process y is determined by the formula: (2)

where are the values of the dynamic error;

4) the value of overshoot j is determined by the ratio of two adjacent maxima (3)

5) the duration of the transition process;

6) the number of peaks during the regulation time.

6.3. Reference disturbances

Disturbances are understood as factors that cause the controlled parameter to deviate from its set value and disturb the balance in the ACS.

To check the quality of the control loop operation, reference perturbations of the following types were introduced.

Perturbation type 1.

To form a disturbance, the position of the control valve stem was changed. The perturbation diagram is shown in fig. 6.3.

1) turn off the actuator of the control valve (for the period of disturbance formation);

2) generate a perturbation by manually moving the valve actuator to the "more" ("less") side by 10-15% of the stem stroke value, focusing on the indicator scale;

3) turn on the drive, determine the deviation value of the controlled parameter and analyze the transient process. If the resulting deviation of the controlled parameter is commensurate with the amplitude of its pulsation and the transient process is poorly visible, increase the disturbance by 1.2..2 times;

4) turn off the drive, generate a corrected disturbance, turn on the drive again. If during the transient process the controlled parameter changes within acceptable limits and this change is clearly visible, we can assume that the reference perturbation has been selected.

Type 2 perturbation.

To apply the perturbation, a change in the task was used. The perturbation diagram is shown in Figure 6.4.

The selection of the parameters of the reference perturbation should be carried out in the following order:

1) stepwise change the task by 10..15% of the value of the control range;

2) determine the deviation value of the controlled parameter and analyze the transient process. If the maximum deviation of the value of the controlled value is small and the transient process is not clearly visible due to pulsations or a small change in the controlled variable, increase the disturbing effect by 2..3 times, taking into account that the controlled parameter during the transient process does not reach the maximum allowable value for this system ;

3) Repeat the experiment, forming a corrected external disturbance. If the transient process is clearly expressed and characterized by a sufficient change in the controlled value, this perturbation can be taken as a reference for this control loop.

6.4. Test procedure for control loops

6.4.1. The procedure for checking the quality of the control loop

The quality of the control loop operation is assessed by the compliance of the registered transient processes (during the formation of external and internal disturbances) with the established requirements.

Checking the quality of the control loop and adjusting its parameters should be carried out in the following order:

1) set the calculated values of the parameters:

setting of the controlled value;

parameters of the PID controller;

2) turn on the ventilation unit and check the operation of the automation system;

3) prepare measuring instruments for registration of parameters;

4) after the ventilation unit reaches the steady state, start testing, introducing disturbances provided for by the test program.

6.4.2. Tests of the control loop when applying disturbance type 1

To test the control loop with disturbance type 1, it is necessary:

Apply a reference perturbation.

3) Process the obtained graphs of the transient process and determine the performance of the control loop in accordance with clause 6.2.

4) At the optimum setting of the control loop, observe the following parameters of the transient process with internal and external disturbances:

the maximum deviation of the value of the regulated value should not go beyond the allowable limits;

the degree of attenuation y must be within 0.85..0.9;

the transition process should not be delayed in time.

5) When adjusting the control loop setting, be guided by the following:

If during the experiment the degree of attenuation of the process is less than 0.85, and the transient process has a pronounced oscillatory character, one should reduce the gain Kp, or increase the integral component Ti;

If the transient process has the form of an aperiodic transient process and is delayed in time, the gain Kp should be increased, or the integral component Ti should be reduced;

· changing the values of Kp, Ti to produce separately;

· To make adjustments when applying internal reference disturbances in the direction of "more" and "less" alternately.

6) Tests are carried out until a satisfactory transient process is obtained.

7) Fix:

the value of the load at which the control loop was tested;

position of the master;

· the value of the reference perturbation;

· parameters of a satisfactory transient process.

6.4.3. Tests of the control loop when applying disturbance type 2

To test the control loop with disturbance type 2, it is necessary:

1) Select the value of the reference internal perturbation according to clause 6.3.

2) Apply the reference perturbation in the following order:

start recording parameter values (regulating action and controlled value);

· fix the value of the controlled parameter 1..3 min before the disturbance and record these values until the end of the transient process every 10..30 s. These intervals are selected depending on the duration of the transition process;

· apply the reference perturbation "greater".

6.4.4. Tests of the control loop in case of emergency decrease in air temperature downstream of the air heater

The operation of the frost protection thermostat is characterized by the following parameters:

operating temperature;

· the value of the minimum temperature of the return heat carrier when the thermostat is activated;

· the duration of the decrease in the temperature of the return heat carrier below the specified minimum value.

Checking the quality of the thermostat and control loop, as well as adjusting the PID controller should be done in the following order:

1) set the adjustment elements to the calculated position: the adjusting element (setter) of the thermostat;

2) put the ventilation unit into operation;

3) control the access to the mode of maintaining the set value of the supply air temperature;

4) install the measuring probe after the air heater;

5) turn on the automatic control system;

6) write down the parameters of the system before applying the perturbation;

7) introduce a perturbation into the system, for which, by gradually closing the valve on the supply pipeline, to achieve a decrease in temperature downstream of the air heater until the thermostat operates;

8) restore the normal heat supply to the air heater, for which fully open the valve on the supply pipeline;

9) process test results;

10) when adjusting the control loop settings, one should be guided by the recommendations of clause 6.4.2;

11) carry out tests until a satisfactory transient process is obtained.

7. RESULTS OF CHECKING THE TECHNICAL CONDITION OF AUTOMATION EQUIPMENT

The technical condition of the automation equipment was checked using measuring instruments according to the list of Appendix 1. The results of the check are given in Appendix 10.

Checking temperature sensors.

The temperature sensors were tested by measuring the resistance of the sensitive element NTC 20, Pt 1000 and comparing the measured value with the table value (see Appendix 10, Table 1) at a fixed temperature at the time of measurements.

The installed temperature sensors were recognized as serviceable, the accuracy of the readings was within the permissible error.

Checking actuators of control valves on heat and coolant.

Control valve actuators of the heating and cooling circuits were tested by comparing the setpoint set from the operator terminal for opening/closing the control valve with the actual position of the valve actuator pointer after the command was processed (see Appendix 10, Table 2).

The actuators of the control valves are in good order and are working out the given commands.

Checking differential pressure sensors on filters and fans.

For verification, pressure was created on the pressure side of the sensor and a vacuum on the suction side. The sensor performance was monitored by turning on the light indicator of the automation board and changing the state of the discrete input of the controller (see Appendix 10, Table 3).

Differential pressure switches are OK.

Checking the frost protection thermostats of air heaters.

The thermostats were checked by cooling the sensing element until the changeover contact of the thermostat mechanically closed. The operability control was carried out by turning on the light indicator of the automation board and changing the state of the discrete input of the controller (see Appendix 10, Table 4).

Thermostats are in good order and provide protection of air heaters from freezing.

Checking air valve actuators.

Checking the actuators of the air valves of the circuits was carried out by comparing the setpoint set from the operator's terminal for opening / closing the control valve with the actual position of the valve actuator pointer after the command was processed (see Appendix 10, Table 5).

All drives are OK. When the fans stop, the drives close.

Checking the performance of control keys, relay contacts and magnetic starters.

The operability of control keys, relay contacts and magnetic starters was checked by mechanically closing the contacts of the corresponding keys, relays and magnetic starters. The operability control was carried out by changing the state of the discrete input of the controller (see Appendix 10, Table 6).

9. TESTING AND ADJUSTMENT WORK

After checking the quality of installation, the technical condition of the automation equipment and eliminating the identified shortcomings, the developed programs were loaded into random access memory devices (RAM) and recorded in the non-volatile memory of the controller. A preliminary check of the correct operation of the programs was carried out using the built-in debugger XwOnline.

The correct operation for the Excel WEB controller was tested using a laptop computer and Internet Explorer browser.

Testing of automation systems was carried out in the sequence determined by the test programs, which are given in Appendices 2, 3.

Before testing, a preliminary testing of the systems was carried out to bring them to a working state. Before the start of each test cycle, the systems were brought to a steady state. The test cycle was considered completed after the completion of the transient process, i.e. until a stable state of the system is restored. The tests were terminated if the measured parameters reached values outside the limits set by the test program.

During the testing, the following conditions were met:

the equipment is in the mode for which the system under test was designed;

· the system under test is in operation and maintains the set value of the controlled variable;

· the adjustable range is sufficient to eliminate the disturbances introduced during the tests;

· during the operation of several control loops interconnected by the technological process (control loops of the first and second heating, humidity, air cooler), first of all, those loops were adjusted and tested that eliminate disturbances arising from the operation of other loops;

· Technological protection devices are included, preventing the occurrence of an accident in case of incorrect operation of the tested control loop.

When adjusting the control loops, the following quality indicators were determined:

· dynamic error ;

degree of attenuation of the transient y

· value of overshoot j ;

the duration of the transient process Тpp;

· the number of maxima of the dynamic error during the regulation time .

The results of calculating the indicators are given in clause 10.

10. Results of tests and commissioning

In the process of commissioning, the following works were carried out:

testing individual elements and aggregates;

actuation of technological protection devices;

Inclusion of systems in operation and their output to the nominal mode;

Adjustment of control loops to maintain the set value of the controlled parameter;

Checking the correctness of the reaction of the control loops to the introduced disturbances;

· adjusting the parameters of control loops.

Testing of elements and assemblies showed that all of them are in working condition.

During the tests, the response of the automation system to the operation of the following technological protection devices was checked:

· capillary thermostats of protection against freezing;

· program thermostats of protection against freezing on the basis of the return heat carrier temperature sensor;

· schemes of control of operation of magnetic starters;

fan belt break sensors;

thermal relays of automatic motor protection devices;

· circuits for shutting down fans on a “FIRE” signal from the building's alarm system.

Checks of technological protection devices were carried out in the following sequence.

The operation of capillary anti-freeze thermostats was tested according to the method described in clause 6.4.4. The thermostat setting was set on its scale at 5ºС. The specified minimum value of the return heat carrier was assumed to be 12 ºС (for the P1-V1, P3-V3, P4-V8 units) and 18 ºС (for the P2-V2 unit). The results of checks when the systems are in operating and standby modes are given in Table 10.1.

During repeated testing of the systems, the set point value was determined at which the parameter = 0. It was 10.5 ºС (for the P1-V1, P3-V3, P4-V8 units) and 16.5 ºС (for the P2-V2 unit).

Table 10.1 - Results of checks of automation systems when triggered

The operation of software anti-freeze thermostats based on the return heat carrier temperature sensor was tested according to the procedure described in clause 6.4.4. The set point for the 52Px _RWFrzPidSet program thermostat controller was set to 12ºС (for the P1-V1, P3-V3, P4-V8 units, x = 1.3.4) and 18 ºС (for the P2-V2 unit, x = 2). The value of 52Px _RWFrzStatSet was taken equal to 10.5ºС (for the P1-V1, P3-V3, P4-V8 settings) and 16.5 ºС (for the P2-V2 installation). The results of checks when the systems are in operating and standby modes are given in Table 10.2.

System B5: 52V 5_RaFanDpsAlm ;

System B6: 52V 6_RaFanDpsAlm ;

System B7: 52V 7_RaFanDpsAlm ;

Automation systems have worked out emergency signals in accordance with the algorithms of the systems (Appendices 6, 7, 8).

When simulating an accident in frequency converters for supply fans of P1-V1 and P2-V2 units, it was carried out by closing the corresponding relay contact. When simulating the operation of thermal relays of automatic motor protection devices (by pressing the “TEST” button on the automatic machines), the corresponding electric motors turned off, the automation systems controlled the equipment in accordance with the algorithms of the systems (Appendices 6, 7, 8).

When the “Fire” signal was simulated, the supply and exhaust fans were turned off from the fire alarm station, the air valves were closed, in the “WINTER” mode circulation pumps continued to work.

When the systems were switched to automatic mode, the sequential operation of units and assemblies was ensured in accordance with the operation algorithms given in Appendices 6, 7, 8.

The duration of the system output to the nominal mode when they are put into operation are given in Table 10.3.

Registration of the Technical report on acceptance, commissioning tests

We ask you to give an explanation on the issue of paying for the execution of the Technical Report on acceptance, commissioning tests and adjustment of electrical equipment in estimates made at the prices of FERp-2001.

In the General Provisions FERp 81-()5-OP-2001 pos. 1.14. stated:

"FERp part 1 does not take into account the costs of compiling the Technical Report, as well as the estimate documentation."

In the Annexes to FERp dated 30.01.2014 No. 81-05-Pr-2001 in table 1.1 it is indicated that the cost of registration of acceptance documentation is 5% of the cost of commissioning.

Usually, in estimates, the cost of preparing a technical report on completed projects is taken in the amount of up to 5% of the cost of commissioning.

Please provide clarification on the issue of the amount of payment for the preparation of the Technical Report.

The amounts of funds for the preparation of a technical report are taken into account in Chapter 4 of the "Consolidated estimate for the commissioning of enterprises, buildings, structures", which is indicated in the corresponding entry in MDS 81-40.2006 "Guidelines for the application of federal unit prices for commissioning".

Chapter 4 of the Consolidated Estimate includes the amounts of funds spent by the Customer for reimbursement in the form of compensation for the costs of contracting commissioning organizations that are not directly related to the implementation of commissioning.

Complex of commissioning works of electrical equipment and electrical installations

Based on the results of the work, a protocol is drawn up in which all the received parameters are displayed, as well as a map for setting up security automation. The result of the commissioning is a certified commissioning of the object ready for transfer to the operation of the Customer.

Develops a work program for commissioning (commissioning program), including measures for labor protection; Transfers to the customer the comments on the project identified during the development process work program; Prepares a fleet of measuring equipment, test equipment and fixtures.

Commissioning of electrical equipment

At the second, no less important, stage, the actual commissioning of electrical equipment takes place in compliance with all electrical safety requirements: the commissioning of the installation and networks is carried out with the supply of electrical voltage.

At this stage, the customer must coordinate with the organization in whose competence the repair and adjustment of electrical equipment, all questions and comments on installation and troubleshoot.

Commissioning, carried out before individual testing of process equipment: - external inspection of electrical equipment for compliance with the project; — verification and adjustment of individual elements and functional groups; - assembly of test circuits; - checking the parameters and characterization of individual devices; — measurement of insulation resistance; - checking the connection of the windings; - adjustment of relay equipment; — verification of the correctness of the implementation of the schemes of primary and secondary switching.

According to the PUE (clause 1.7.3, edition 7), the project provides for the “TN-S” grounding system (zero protective PE and zero working N conductors are separated throughout). In accordance with the requirements of VSN 012-88, all cables laid in the ground, as well as an external grounding device, are subject to intermediate acceptance with the preparation of an act for hidden work.

During the verification, the degree of their safety and reliability, compliance with the declared design characteristics is determined. Based on the results of the work, all identified shortcomings that impede the normal operation of the equipment are eliminated. Installation and commissioning are carried out by specialized organizations with which the enterprise concludes a business contract.

If the enterprise has trained engineering and technical personnel and the necessary instrumentation, then these works can be performed on their own.

An individual heating point cannot be considered operational and ready for use until it has undergone a number of procedures, including electrical installation and commissioning procedures, installation of thermal and mechanical structures. Upon completion of these activities, the ITP is directly put into operation, accompanied by the signing of the following ITP adjustment acts: - intermediate for the thermal mechanical part of the equipment and carrying out hidden measures, as well as for electrical installation and automatic operation, - final for the approval of electrical equipment and heat-consuming installation as a whole. The final one is an act of technical acceptance, which is signed by the receiver and the further owner of this design.
