A Study on Energy Saving of Condensate Pump Speed Regulation improvement for CPR1000 Nuclear Power Unit

Abstract To reduce the energy consumption of nuclear power plants, this paper studies control mode changing condensate pump frequency to variable speed regulation, using permanent magnet flexible transmission technology change pump, and strategy deaerator water level outlet pressure is redesigned achieve purpose saving. Through study strategy, process design analysis, theoretical calculation, simulation full-range simulator, feasibility proposed method confirmed, which provides an important reference for improvement saving regulation auxiliary machines in plants.
