摘　　要：互联电网的传输能力和安全运行与电力系统稳定性密切相关,提高电力系统的稳定性一直是电网发展的重点。论文基于Matlab构建电网的仿真模型,模拟调速系统和励磁系统对发电机的控制作用。仿真结果表明,调速系统和励磁系统能对电力系统中的发电机进行有效的稳定控制,为实现抑制低频振荡,进一步提高电力系统的稳定性奠定了基础。Transmission capacity and operation safety of the interconnected power grid is closely related to the stability of power system, so how to improve power system stability has always been the focus of power grid development. In this paper, the simulation model of power grid is based on Matlab to simulate speed control system and excitation system which controls generator. The simulation results show that speed control system and excitation system can effectively control the generators stability in the power system. It lays a foundation for further improving the stability of power system to achieve the suppression of low frequency oscillation.
