Today, the software and technical complex based on the above-mentioned equipment performs the following functions:

  • • Information functions

    The installation automation system provides:- automatic and manual control of processes;- remote and local drive control modes;- diagnostics of measurement channels with automatic decision-making or with a prompt to the operator;- warning and emergency signaling;- automatic installation protection;- automatic correction of costs by pressure and temperature;- control and archiving of technological parameters of boiler operation;- system settings from the engineering automated operator's workplace;- event logging;- generation of daily reports on the main technical and economic indicators of the station (installation);- calculation of power and installation efficiency coefficient;- online web access;- use of touch tablets for the operator and engineer.Purpose of information functions:- introduction of analog signals of sensors and primary converters of technological parameters;- input of discrete signals;- control of the reliability of entered signals;- normalization and filtering of input signal values;- mathematical processing of normalized signal values;- control of values ​​of calculated parameters and indicators for technological and emergency tolerances;- data generation for dispatcher control;- display of operational information about the progress of the technological process and the state of the equipment;- formation of emergency and technological alarms;- formation of daily protocols (reports) of the results of the flow of the technological process and the operation of the main equipment;- formation of a system protocol of events;- output of output video frames (mnemonics) operational information about the progress of the technological process and the state of the equipment;- output of output video frames (mnemonics) of formed protocols and reports;- printing output documents;- archiving of equipment operation parameters over time.It is possible to use the function of extracting the square root in the controllers when measuring the pressure drop to determine the flow rate and enter corrections for changes in the pressure and temperature of the measured medium by software.Control of all sensors of analog information during its primary processing is carried out by analyzing the signal for the minimum and maximum value.It is possible to filter the signal.To increase the reliability of the system, signal duplication is introduced for some parameters. At the same time, the duplicated signals are spread across different input-output stations.

  • • Detection, signaling and registration of parameter deviations from the set limits

    Notifications about the status and violations of the technological process, about violations of the state of system elements are issued to operational personnel with the help of video frames on automated workplaces and to the printer.Notifications of deviations of a warning and emergency nature are issued proactively. The algorithm for generating warning and emergency signals provides:- turning on the flashing of the element on the mnemonic and turning on the sound alarm;- confirmation by the operator of sound and flashing;- illumination after confirmation with even light, if the situation persists;- registration of the time of appearance and confirmation of the alarm.

  • • Manual data entry

    Manual setting parameters are entered as follows:- the values ​​of the control task setting parameters (start and end of the scale, lower and upper limits of the warning alarm, lower and upper limits of the emergency alarm) are entered in real time;- coefficients and constants (filtering coefficient, zero cut-off, alarm hysteresis) are entered in real time.It is possible to protect individual parameters from entering impermissible values.It is also possible for the operator to manually enter an event into the event log on the automated workplace screen (replacing the paper event log).

  • • Mnemonic diagrams reflect the current state of the object in dynamics

    The following information is displayed on the mnemonics:
    - the name of the mnemonic scheme;
    - scheme of the technological equipment section;
    - value of measured parameters.

  • • Displaying trends

    Two types of trends are expected:
    - historical graph - the history of the parameter over a long period of time with archiving in non-volatile memory;
    - operational graph - the history of the parameter in a relatively short period of time with storage in RAM.

  • • Formation and printing of reporting documents

    The system provides for the formation and display on the monitor, as well as printing in the form of a separate document "Message Protocol" - a reporting document in which the following events are recorded in chronological order:
    - deviation of parameters from permissible limits;
    - returning the parameters to the regulatory limits;
    - information about turning on and off engines, mechanisms;
    - information on issuing control commands;
    - diagnostic messages;
    - activation of emergency event recorder signals.
    When recording an event, the time of appearance and confirmation of the event is indicated.

  • • Auxiliary functions

    Auxiliary functions include:
    - testing and self-diagnosis of the state of system elements;
    - verification of the reliability of information signals;
    - registration of errors, failures, malfunctions;
    - setting a ban or permission to pass information through measurement and signaling channels;
    - time server settings;
    - restricting access to changing the settings of system parameters at the "operator" and "engineer" levels by setting passwords.

Designing

We carry out design and construction documentation in the following sections:
AK – automation and control of production processes;
EM – power electrical equipment, networks 0.4 kV;
EO - electric lighting;

Designing can be one- or two-stage.
One-stage project: RP stage (working project)
Two-stage project: stage P (project), stage P (working documentation)

All our projects are carried out in accordance with the norms and rules of DBN and PUE, comply with DSTU and ISO standards.
When developing CHP projects, we use the European equipment classification and coding system KKS (Kraftwerk-Kennzeichensystem).

The main software we use for designing is EPLAN Software & Service GmbH & Co., additionally Autodesk Autocad.
The main modules of the EPLAN platform that we use are:
EPLAN Electric P8 is a modular and scalable solution for electrical engineering design, automatic creation of project and work documentation.
EPLAN Fluid - software for the design of pneumatic/hydraulic automation, lubrication and cooling systems and the automatic creation of the corresponding design and work documentation
EPLAN ProPanel - 3D design of electrical cabinets with data transfer to production. Virtual three-dimensional modeling, creation of two- and three-dimensional drawings, three-dimensional image of leading and route diagrams, availability of templates for the operation of drilling equipment and integration with CNC machines
EPLAN FieldSys - work with track plans
EPLAN PrePlanning - software for preliminary (sketch) design of objects and generation of project documentation. It is used to create functional automation schemes.

The principles used in the construction of the ASK TP:
ASK TP is a PTC consisting of sensors, actuators, controllers, servers, operator workstations, active and passive local computer network equipment, as well as standard basic and application software used to create modern distributed control systems.
The control and automation system is usually distributed and multi-level. It provides control of parameters with the help of converters and secondary devices installed on the KVP and A panels, as well as the operator's workstations (automated workplaces). Management of executive mechanisms is possible both manually on site, and remotely from the APM or automatically according to programmed algorithms.
1st level - "Field" (sensors, converters and actuators installed on site near the equipment);
2nd level - "Lower" (PLCs installed in an air-conditioned switchboard; remote distributed input-output stations, which can also be installed locally near the equipment, to save on cable and wire products; frequency converters, operator touch panels); As a PLC, we use controllers from well-known manufacturers: Siemens, Schneider, ABB. Siemens, Delta Electronics operator panels.
Level 3 - "Upper" (a client-server structure can be applied (duplicated servers installed in the server rack and operator ARMs installed in the main operator room), and individual workstations (standalone) can be used. As a SCADA program of the upper level, Simatic WinCC Professional is used as a part of "TIA PORTAL". The possibility of connecting to the Internet is also provided, which allows monitoring the processes of the station remotely, through the web interface or the software product "WinCC Webnavigator".
The software of the controller and the upper level of the system provides the possibility of developing, modifying and debugging programs both in OFF-LINE and ON-LINE modes, that is, without interrupting the functioning of the system.
In PTK, reservation of lower and upper level networks is established. The underlying network of the lower layer is usually with "Profinet" data transfer protocol, 100Mbps data rate, copper cable, device-to-device ring network topology. When the distributed input/output stations are separated by more than 100m, an optical data transmission medium is used. The upper-level network is usually built on the basis of Ethernet with a data transfer rate of 1000Mbps and is implemented using industrial switches with the function of network redundancy. Hybrid topology: ring and star-shaped. The switches are powered by a redundant power source (two independent inputs with an automatic switching circuit and power supply through a UPS).
In agreement with the customer, to reduce the number of cable products in the automation system, frequency converters with a hybrid control scheme can be used: via the PROFINET network and, in the event of its complete interruption, control by discrete signals.
Automatic adjustment, protection and blocking are implemented at the PLC level and in case of complete loss of communication with the ARMs - they always remain in operation.
Touch control panels are used for the possibility of controlling some equipment on site and to increase the reliability of the system (in case of loss of control due to ARMs).
When designing PTK, the principle of standardization and unification is applied, which consists in the rational application of typical, identical, unified and standard circuit solutions, structures and equipment components.
When designing, the required number of input/output channels and reserve channels is assumed to be at least 10% for each type of signals.
PTK equipment is placed in industrial electrical cabinets with a level of protection not lower than IR54.
