Abstract

Based on the similarity of steam turbine in nuclear power unit and in thermal power unit

working characteristics of the former one was analyzed

combining with its specific structure.By using mechanism modeling method

the primary frequency modulation model for steam turbine on nuclear power unit was established

with reference to the characteristics of steam turbine on thermal power unit.This method was used to build the power frequency control system for steam turbine.Simulation results for this control system by employing Simulink software show that

this power frequency control system can effectively reduce the actual fluctuation rate of grid frequency

and realize the initial tracking of grid load.
