According to the characteristics of the prime mover and its governor, this paper sets up the dynamic simulation system of the prime mover and its governor based on the microcomputer, converter technology and DC electric machine. As the application of the microcomputer, the dynamic simulation system is flexible and can be used to simulate different types of prime movers conveniently. One special integrated circuit module is adopted to perform phase shifting and triggering of the converter. At the same time, a simple speed detector based on infrared ray is proposed which is reliable and can be installed easily. The test results of its dynamic simulation are satisfactory.
