APCS of the power-generating unit No. 1 of Krasnoyarsk CHPP-3
Specialists of CJSC "Tornado Modular Systems" company are finishing adjustment of APCS of the power-generating unit No. 1 of Krasnoyarsk CHPP-3. The system is designed for automation of monitoring and control of the technological processes and operating modes of the thermotechnical and electrotechnical equipment of the power-generating unit No. 1 and the plantwide equipment in the thermotechnical and electrotechnical section of the power-generating unit No. 1 of Krasnoyarsk CHPP-3.
The system is designed as a technically distributed system, which follows the principle of centralized automated monitoring and control of the power-generating unit from the facility control desk with participation of the operational staff.
The System is based on DCS “Tornado” and consists of a programmable microprocessor-based technologies and non-programmable automation tools (sensors, actuators, traditional monitoring and control tools and power actuating devices of different purposes)
Expedient number of the monitoring and local control desks of a package supply with the technological equipment, which do not require a constant presence of the operational staff can be kept at some technological units of the power-generating unit.
In general, two distributed control systems (DCS) are allocated in the system:
- DCS of the power-generating unit No. 1, including the plantwide thermotechnical section (DCS-Unit1);
- DCS of the plantwide electrotechnical section (DCS-Electrical).
DCS-Unit1 and DCS-Electrical are autonomous and can work independently of each other.
The information exchange between the DCS-Unit1 and DCS-Electrical is performed via the local network.
Automation object
The automation objects are:
- The power-generating unit No. 1 consisting of:
- Boiler unit of Ep-670-13,8-545 BT type;
- Turbine of T-185 / 220-12,8-2 type;
- Generator of TSFP 220-2U3 type;
- Auxiliary equipment of the power-generating unit;
- Plantwide thermotechnical equipment of the main building of the start-up complex of the power-generating unit No. 1;
- Plantwide electrotechnical equipment of the start-up complex of the power-generating unit No. 1 as part of the main scheme.
