STATCOM在电力系统故障时的动态特性仿真研究

The Application of the Protective Control on the SATCOM

采用MATLABPSB建立了STATCOM的时域仿真模型,以实例对STATCOM在系统故障时的动态运行特性进行了仿真研究。结果表明,当控制器采用常规的算法时,STAT COM的运行可能会严重偏离其正常运行条件,此时STATCOM无论是退出运行或继续存在于系统都可能加剧系统的故障状态。

A simulation model of a simple power system with STATCOM is built by MATLAB PSB. The dynamic characteristics of the STATCOM in the fault of power system are studied by simulation. The simulation results show that under large disturbance, the normal condition of the power system with STATCOM cannot be maintained. Whether STATCOM maintains in or retreats from the power system, in both cases STATCOM could aggravate the fault status.
