en.Wedoany.com Reported - KRUG Company (КРУГ) has integrated the automatic control subsystem of the electrical part of the control system (ЭЧСР) into the existing process control system (АСУ ТП).

The АСУ ТП for the turbine unit, including the ЭЧСР subsystem, is a standard technical solution from the Scientific and Production Firm «КРУГ» (KRUG Research and Production Company), which has been implemented in multiple projects.

Ufa Thermal Power Plant-4 (Уфимская ТЭЦ-4) is a branch of Bashkir Generating Company (Башкирская генерирующая компания), supplying energy to the industrial zone of Bashneft-Ufaneftekhim (Башнефть-Уфанефтехим), a subsidiary of Bashneft Oil Company (АНК «Башнефть»). It has an installed capacity of 270 MW and a thermal capacity of 792 Gcal/h. The primary fuel is natural gas, with heavy fuel oil as a backup.

The ЭЧСР is an integral part of the turbine electrical control and protection system, responsible for the following tasks: controlling the steam distribution mechanism nodes of the turbine; maintaining operational parameters of the turbine unit; implementing optimal logic control algorithms, process protection and interlock algorithms, and regulation algorithms; maintaining the specified rotor speed of the turbine with a defined regulation unevenness.

All equipment and software used in the system are domestically produced. The АСУ ТП and ЭЧСР subsystem for the turbine Р-50-12,8/1,5 (Unit No. 9) operate based on the domestic hardware and software (program-technical) complex ПАК ПТК КРУГ-2000®. The upper-level software uses the domestic SCADA system КРУГ-2000. The automatic control of the electrical regulation system for turbine operating parameters is implemented using the microprocessor-based industrial controller TREI-5B-04 Standard (programmable logic controller), which is pre-installed with the controller real-time system (СРВК).

The main feature of this system is the use of a unified platform for a comprehensive automation solution for the turbine unit (including ЭЧСР), thereby achieving a higher quality level. This allows operational and maintenance personnel to view the complete picture of the technological process and perform control and adjustments from a single system and a single automated workstation.
