【摘要】 介绍电力系统动态模拟过程中采用物理模拟与数字模拟的模数混合模拟的方法：对主设备如发电机、输电线路、负荷等采用物理模拟，而对调节器如励磁、调速等采用数字模拟；重点介绍了数字模拟过程中，电压、电流、功率、转速、转矩、功率因数角及负荷等测量接口电路的实现方法更多还原

【Abstract】 In this paper,a hybrid simulation System of Motor Generator model is described.The main facilities such as generator,transmission line and load are simulated by scale-down physical models,the control systems such as the exciter and governor are presented by the microcomputer-based digital models. A variety of power system phenomena and behaviors can be conducted with flexibility and directly perceived through the senses in this lab. A detail description is given in the paper with emphasis on the design of different type of transducers and interface circuits with the control system.更多还原
