5.Results of analysis of design documentation and quality control of installation work

The project of automation of ventilation systems (section of the AOB brand) and installation of automation systems have been completed

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

The performed verification of the conformity of the installation of automation equipment to the project and the requirements of the manufacturers did not reveal significant deficiencies and defects.

6. INDICATORS OF THE REGULATION CIRCUIT OPERATION QUALITY 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 in the form closed system automatic control (ACS) with regulation according to the Polzunov-Watt principle. The structural diagram of the automatic control system is shown in Fig. 6.1, where the following designations are adopted:

Δу is an adjustable parameter;

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

u - control action;

g - disturbing effect;

КР - gain factor;

Ti - constant of integration;

Тд - constant of differentiation.

The choice of the type of control law was 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;

return heat carrier temperature after the first heating air heater;

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

6.2. Performance indicators of the control loop and

transition process. The evaluation of the control loop operation 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 Figure 6.2):

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

2) the 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. During oscillatory transient processes, several maxima are observed and, consequently, the values ​​of the dynamic error: (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 amount of overshoot j is determined by the ratio of two adjacent maxima (3)

5) the duration of the transient process;

6) the number of maxima during the regulation time.

6.3. Reference disturbances

Disturbances are understood as factors causing a deviation of the controlled parameter from its specified value and disturbing the equilibrium in the automatic control system.

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

Perturbation of the type 1.

To generate a disturbance, the position of the control valve stem was changed. The disturbance diagram is shown in Fig. 6.3.

1) turn off the control valve drive (during the formation of the disturbance);

2) generate a disturbance by manually moving the valve actuator towards "more" ("less") by 10-15% of the stroke value, focusing on the pointer scale;

3) turn on the drive, determine the value of the deviation 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 the drive back on. If during the transient process the controlled parameter changes within acceptable limits and this change is clearly visible, we can assume that the reference disturbance is selected.

Perturbation of the type 2.

A task change was used to create outrage. The disturbance diagram is shown in Figure 6.4.

The selection of the parameters of the reference disturbance should be performed in the following order:

1) abruptly change the reference by 10..15% of the value of the regulation range;

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

3) Repeat the experience, forming a corrected external disturbance. If the transient process is clearly expressed and is characterized by a sufficient change in the controlled value, this disturbance can be taken as a reference for a given 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 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 done 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 control the operation of the automation system;

3) prepare measuring instruments for registration of parameters;

4) after the ventilation unit reaches a steady state, proceed with the tests, introducing the perturbations stipulated by the test program.

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

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

· Inflict a reference indignation.

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

4) Observe the following parameters of the transient process with internal and external disturbances with the optimal adjustment of the control loop:

the maximum deviation of the value of the controlled variable should not go beyond the permissible limits;

attenuation degree y should be within 0.85..0.9;

the transition process should not be prolonged in time.

5) When adjusting the control loop setting, observe 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, the gain Кр should be reduced, or the integral component Ti should be increased;

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

· Change the values ​​of Кр, Ти separately;

· Make the correction when supplying internal reference disturbances in the direction of "more" and "less" alternately.

6) Carry out the tests until a satisfactory transient is obtained.

7) Fix:

· Value of the load at which the control loop was tested;

· Position of the dial;

· The value of the reference disturbance;

· 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 of type 2, it is necessary:

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

2) Apply the reference disturbance in the following order:

· Start recording the values ​​of parameters (control 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 transient;

· To inflict a reference indignation "more".

6.4.4. Tests of the control loop in case of an emergency drop in air temperature behind the air heater

The operation of the anti-freeze thermostat is characterized by the following parameters:

· Temperature of response;

· Value minimum temperature return coolant when the thermostat is triggered;

· The duration of the decrease in the return heat medium temperature below the set minimum value.

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

1) set the adjustment elements in the calculated position: adjusting element (adjuster) of the thermostat;

2) turn on the ventilation unit;

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

4) install the measuring probe behind the air heater;

5) turn on the automatic control system;

6) write down the parameters of the system prior to the disturbance;

7) to disturb the system, for which gradually closing the valve on the supply pipeline, to achieve a decrease in the temperature behind the air heater before the thermostat is triggered;

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

9) process the test results;

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

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

3. TEST CONDITIONS

Commissioning tests of the boilers were carried out under normal operating conditions.

During the preparatory work preceding the tests, the technical condition of the boiler equipment was checked.

Before the start of the balance experiments, rough experiments were carried out in order to identify the critical excess air at each load. To construct the characteristics of the boilers, ensuring the reliability of the measuring information, two load modes were worked out on the boilers, while, to eliminate errors, each of the experiments was duplicated.

The load was generated by the facility's heating and hot water system.

The main fuel consumption was measured using a meter installed at the gas inlet to the boiler room with temperature and pressure adjustments on the controller.

The safety automation ensures that the fuel supply to the burner is cut off when the limit values ​​of the following parameters are reached:

• differential air pressure on the burner fan;
• boiler water pressure;
• gas pressure in front of the cat;
• boiler outlet water temperature;
• extinction of the burner torch;
• malfunction of protection circuits, including loss of voltage;
• activation of the fire alarm in the boiler room;

ANNEXES

1. Permits documentation

In the implementation of many projects, capital construction or reconstruction of buildings and structures is carried out with the installation of new equipment or specialized processes. Such works include the installation of fire extinguishing systems, power supply, air conditioning, ventilation, fire alarm systems. All of them require commissioning, for this in recent times more and more often a PNR program is being drawn up.

What is PNR and why are they carried out

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

The implementation of all these manipulations is usually carried out on a contractual basis by specialized organizations that have the necessary approvals and a staff of qualified specialists. The necessary conditions for their activities on the site (industrial sanitation, labor safety) are organized by the customer, who also pays for the commissioning and commissioning work at the expense of the general estimate for the commissioning of the facility. 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 commissioning:

• Individual tests are actions that are designed to ensure that the requirements are met. technical conditions, 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 committee.
• 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 interrelated working together of all installed equipment at idle speed, then under load, after which the process mode envisaged by the project is reached.

Although not spelled out in law, in recent years, the customer has increasingly requested that a commissioning program be drawn up for testing. This gives confidence that not a single nuance will be missed, and that the operation of all systems will comply with the approved standards and project documentation.

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

The commissioning program is a document that clearly outlines the entire list of actions that will be performed by the responsible organization. On the web, you can see discussions about whether it is worth including in the Program the methodology for carrying out commissioning, 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 the 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 the equipment in a visual mode (control devices, valves, filling the system with water), based on the results, a defective statement is drawn up;
• commissioning tests in operating conditions, balance experiments (setting optimal modes, testing valve control in manual and automatic mode, checking automation settings, identifying deficiencies and working out proposals for their elimination), the result is an individual test report;
• complex testing (72 hours of continuous operation - for all main equipment, 24 hours - for heating networks), its beginning is considered to be the start time of all systems at maximum load.

Some companies draw up all activities directly related to the preparation and testing of devices in a separate document - the PNR 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.

The following additional documents may be an integral part of the Program:

• passports of ventilation, heating and hot water supply systems, as well as individual nodes of their connection;
• the procedure for the preparation and subsequent conduct of the commissioning with a list of all operations, the time of their beginning and end;
• list of stationary and portable measuring instruments (manometers, thermometers, etc.);
• a list of control and stop valves, equipment (pumps, valves, heat exchangers, filters);
• a list of control points and a 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);
• 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, comprehensive testing and performance tests, a commissioning certificate is drawn up with the corresponding appendices (a list of mechanisms and equipment on which adjustment and testing was carried out).

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

TECHNICAL REPORT

on the commissioning of the cascade system installed at:

____________________________________

Director of JLLC

Ch. SOOO engineer

Minsk, 2007

General information.

The cascade system is designed for cooking hot water used in closed heating systems with forced circulation of the coolant and for the preparation of hot service water using a storage or high-speed boiler in gasified buildings with power supply and central or individual water supply. The cascade system includes two or more wall-mounted condensing heaters with a thermal power of 50 kW with a closed combustion chamber, which provide water heating for two heating circuits and one circuit for preparing hot water in a capacitive boiler.

The distribution of the total heat output to several units guarantees the supply of heat even in the event of a malfunction of an individual unit in the cascade system.

The cascade system of heating devices provides greater gas savings compared to a single boiler of the same capacity. This is achieved due to the automatic selection of the required thermal power by the cascade to ensure the specified temperature parameters.

Installation, connection, commissioning and testing of the apparatus were carried out according to the project developed in accordance with the applicable rules and regulations, and approved in accordance with the established procedure in compliance with the Building Norms and Rules (SNiP) and Building Norms of Belarus (SNB): SNiP 2.04. 05-91 "Heating, ventilation and air conditioning", SNB 4.03.01-98 "Gas supply", SNB 3.02.04-03 "Residential buildings", SNiP 2.08.02-89 "Public buildings", "Rules technical safety in the field of gas supply of the Republic of Belarus ”and other applicable regulatory documents.

The installation of the cascade system is carried out in accordance with the project developed by: _______________________________________________________.

Commissioning works were carried out by the JLLC service department in accordance with the contract: _______________________________________________________.

Methods of carrying out commissioning works

cascade system.

The combustion mode was adjusted by adjusting the gas valves in the boilers of the cascade system. At the same time, the maximum and minimum level of modulation of the gas flame were set taking into account the power of the boilers, the power consumption, the gas pressure in the network, the thermal insulation properties of the building, and the vacuum in the gas duct.

During commissioning, the necessary measurements were carried out to determine the main indicators of the boilers:

Gas pressure in the network;

Maximum working gas pressure in the boiler;

Minimum working gas pressure in the boiler;

Gas pressure during ignition;

Vacuum in the gas duct;

Outside air temperature;

Water pressure in the heating system.

The measurements were taken at different loads during the operation of each boiler and the entire cascade system as a whole. The duration of measurements and settings for each boiler was 30 minutes.

Cascade system control unit programming

The control unit is designed for programmed control of a heating and hot water supply system containing up to two heating circuits, a boiler water heating system.

The block provides the following operating modes:

Auto mode;

Continuous heating and hot water supply mode;

Economy mode;

Frost protection mode;

Summer mode.

Each heating circuit is controlled by a sensor installed in the heated room or indirectly by two sensors: a sensor in the heating circuit and an outside air sensor.

Programming was carried out in automatic mode, i.e. heating control ensures that two set temperatures are maintained according to the established schedule. During the day, 3 periods of time for maintaining a comfortable temperature were set, and the rest of the time the set reduced temperature is maintained. Periods of maintaining a comfortable temperature were set for each day of the week. Three periods of time for hot water preparation have been set, which ensures the preparation of water at a given temperature at a specified time (in the case of installing a hot water system). Automatic switching on and off of circulation pumps is programmed, forced circulation mode for 5 minutes.
