摘要

In the research of power system simulation, the accuracy of machine electricity transient study mainly depends on the precision of prime mover and governor system simulation, which plays important role in the power system research on transient stability and static stability when disturbance occurs. Based on the equation of motion, the torque was calculated by method of digital simulation to control the government system. The engine inertia and government system was simulated by the method of hybrid simulation. The results show that this simulation can fulfill the requirements of faster responds and higher accuracy.%模拟电力系统的模拟研究中,柴油机及其调速系统直接影响系统机电暂态过程的准确性,对于判别系统受到大扰动后的暂态稳定和受到小扰动后的静态稳定性具有重要意义.从电站柴油发电机组的运动方程出发,在柴油机及其调速器数学模型的基础上,利用数字仿真计算机实时计算模拟转矩指令,用以控制一套高性能交流调速系统,从而实现电站柴油发电机组中柴油机及其调速器与系统转动惯量的数模混合模拟.实验表明,该模拟系统通用性强,响应速度快,准确性较高.
