摘　　要：基于核电机组汽轮机与火电机组汽轮机的相似性,结合核电机组汽轮机特有的结构特点,分析了其工作特性。采用机理建模方法,并参考火电机组汽轮机特性建立了核电机组汽轮机参与一次调频的模型,使用该模型构建了汽轮机功频控制系统。采用Simu-link软件对该控制系统的仿真结果表明,汽轮机功频控制系统可较好地缓解电网频率的实际波动速率,实现对电网负荷的初步跟踪。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.
