Hydro unit automated control system supplied by Rakurs Group has been commissioned at Novosibirskaya HPP after overhaul of hydro unit No. 1 and replacement of Kaplan turbine to a new one. The system has been based on Siemens industrial controllers series SIMATIC S7-400.
The system contains the following hardware and software complexes (PTC):
MNU – control of oil pressure unit;
EHR – electrohydraulic regulator providing Kaplan turbine regulating bodies drive control;
ASUG – hydro unit automated control system performing control of hydro unit, hydromechanical protection and alarm system modes of operation;
TC – thermal control providing temperature control of hydro unit main connection joints and auxiliary equipment;
VC – vibration control providing technological control of hydro unit vibration parameters.
Automated control system (ASUG) provides hydro unit operation in the following modes:
· Turbine idle run
· Generator idle run
· Generator mode
· Synchronous compensator mode
This is a standard list of modes typical for a majority of HPP hydro units. Rakurs has gained a rich experience in similar systems designing.
Successful completion of hydro unit No. 1 automated control system start-up and adjustment has resulted in Rakur’s possibility to conclude a new contract for hydro unit automated control system supply for the rest 6 units of Novosibirskaya HPP. The contract’s performing is planned till 2018.
