摘　　要：基于抽水蓄能电站机组运行于水泵抽水时的同步电动机相量图和电机线性化Philips-Heffron模型,分析同步电动机线性化模型中各参数特征,从而推导同步电动机励磁调节力矩传递函数及其相频特性,得到同步电动机励磁调节正阻尼力矩的条件,并提出获得附加正阻尼力矩方法,给出一个基于PSS2B的模型框图和工程应用结果。Based on the phasor diagram of synchronous motor and the linearized Philips-Heffron model of synchronous motor when the unit of pumped storage power station is running when the pump is pumping,the parameter characteristics in the linearized model of synchronous motor are analyzed,the transfer function and phase frequency characteristics of excitation regulation torque of synchronous motor are deduced,and the conditions of positive damping torque of excitation regulation of synchronous motor are obtained,A method to obtain additional positive damping torque is proposed,and a model block diagram based on pss2b and engineering application results are given.
