摘要
本文对一个含两台水轮发电机组的输电系统进行暂态稳定性研究仿真演示。为提高系统的暂态稳定性和阻尼振荡能力,该系统中配置了静止无功补偿器(SVC)以及电力系统稳定器(PSS)。介绍了电力系统稳定器(PSS)和静止无功补偿器(SVC)的基本功能,利用MATLAB仿真软件的Simulation工具箱对一个双机系统进行了建模和仿真,将系统的工作过程及有关波形准确直观地显示出来。
This paper introduces a system of two-turbine generator＇s transient stability simulation. In order to improve transient stability and damping oscillation ability of the system, the system is configured with static var compensator（SVC） and power system stabilizer（PSS）.Including the basic function of power system stabilizer（PSS）and static var Compensator（SVC）.With using Simulation toolbox of MATLAB, simulates a two-machine power system. This software can demonstrate the systematic work process and the related waveform intuitively and accurately. According to simulation result, it analyzes the impact of PSS and SVC on the voltage stability when a single-phase fault or three-phase fault happens.
