电站仿真系统中的发电机异常运行建模

现役的电站仿真系统多集中于正常运行和操作的培训仿真。结论科研生产要求，设计和建立一类具有异常运行和故障工况仿真功能的培训系统是当前电站仿真建模发展的需要，文中结合国内某水电站培训系统的一发，将异常运行模块引入护真培训系统，重点讨论了异常运行中最常发生的失磁异步运行和机组甩负荷模块的机理、算法和计算实例。联调结果显示，与实际运行相吻合。

MODELING OF GENERATOR''S ABNORMAL RUNNING MODE IN POWER STATION SIMULATION

At present the plant simulators mostly concern normal running and operation sim ulation.With the dem ands of research and production,it is an urgent requirement of power station development to design and establish a type of new training system including abnormal running and fault condition sim ulation. So based on the development of the simulation training system for a domestic hydroelectric power station,this paper introduces the abnormal running model in simulation system and m ainly analyzes the theories,m ethods and instances of two accidents which m ostly often occur:losing excitation and load- shedding.The results show the agreement with the practical situations.
