Automatic Process Control System of a power plant is a three-level system. 

   1. Low level provides: 
  • Direct control of technological equipment of a power plant. 
   2. Medium level provides: 
  • power plant technological equipment automatic control; 
  • Technological process parameters control of all the modes of Gas Turbine Power Plant operation, including starting sequence and shut down of certain equipment; 
  • realization of all level safety automaton and its software hardware backup; 
  • automatic start and shutdown of the main power equipment; 
  • passing all the collected data to the top level control system. 
   3. Top level, realized at HMI and servers, provides: 
  • integration of all the automatic control subsystems of the plant (UCP, compressors, associated substations, firefighting automation, Gas Turbine Power Plant electrical equipment, common plant equipment); 
  • plant equipment remote control; 
  • power plant control system parameter adjustment; 
  • backup of technological parameters, technological equipment status, trips, operator and other personnel actions. 
  • reporting to the operating and technical personnel on all the technical data; calculation of the parameters, preparation of protocols and other operating documents for printing; 
  • Control access ranging. 

Automatic Process Control System completes the following power plant operation management tasks: 

When Gas Turbine Power Plant operates online with the grid: 
  • Control of the active power balance between the power system and Gas Turbine Power Plant; 
  • Active power spread between power units working in parallel; 
  • Reactive power balance between the power system and Gas Turbine Power Plant; 
  • Reactive power spread between active power units operating in parallel. 
When Gas Turbine Power Plant operates offline: 
  • Voltage adjustment, reactive power spread between the power units working in parallel, reactive power control; 
  • Frequency control, active power spread between the generators, active power adjustment. 
  • Automatic switching from offline to online operating mode: 
  • Electric circuit setup (auto synchronizer input/output connection); 
  • Automatic and manual synchronization of 6kV and 110KV breakers. 
Automatic Process Control performs parametric diagnostics, technical and economical analysis of GTPP performance. On operator request the following functions can be performed at the set intervals: 
  • actual GTPP performance parameters comparison with the calculated values; 
  • calculation of GTPP performance; 
  • gas consumption calculation; 
  • calculation of fuel utilization coefficient; 
  • heat generation calculation.
