摘　　要：基于模块化建模方法．对独立存在的厂用电继电保护系统仿真模块进行了分析和建模，给出了电流互感器、中间继电器、时间继电器、电流继电器等的仿真模型；建立了典型断路器控制回路和电流速断保护仿真数学模型。将所建模型应用到某火电厂培训仿真机上，取得了满意的效果。Based on the module modelling methods,the relay-protect simulation modules of a power plant auxiliary power system is analyzed in this paper.Some mathematical simulation models are presented,such as the current transformer's model,mid-relay's model,time-relay's model,current-relay's model etc.A typical breaker's controlling circuit mathematical model and an instantaneous cut-off current relay-protect simulation model are also obtained.It is shown that the simulation results of Fularji General Power Plant's full-scale power plant training simulator are quite satisfied.
