在输电系统中发生单相，三相故障时对电力系统稳定性影响较大。因此，故障切除后，引起系统电压和功率振荡。本文在Matlab／simulink环境下对简单的电力系统安装TCSC模块进行单相，三相接地故障仿真，分析了TCSC模块对电力系统暂态稳定性的影响。仿真结果表明安装TCSC模块后系统稳定性明显提高，负载电压和功率很快恢复到稳定状态。

The power system stability will be effected when a single phase or three phase fault occurred in the transmission system .As a result,it will cause the oscillation of system voltage and system power .In this pa-per , the Single phase and three phase grounding fault simulations have conducted to simple power system in -stalled TCSC modules in the Matlab/simulink, analyzed the effect TCSC module on the power system transient stability .The simulation results show that the system stability improved obviously and The load voltage and power soon reverted to its steady state after installing TCSC modules .
