摘　　要：由于基于电力电子逆变技术的无功补偿装置——静止同步补偿器(STATCOM)采用了GTO,IGBT等大功率全控型器件,因此能够更快速、更有效地补偿系统中的无功功率,而且补偿容量不受装置容量限制,调节特性更优。通过以含有STATCOM的风电系统为例,结合电流间接控制方法,仿真分析了STATCOM在系统暂态故障过程中的调节作用。仿真结果表明,STATCOM在维持系统电压稳定和提高电力系统的暂态稳定极限上发挥了很大的作用。The STATCOM based on the electrical adverse convert technology applied the high power components such as GTO,IGBT, as a result, it can be more quickly and more efficiently for compensating the active power of the power system, and the compensator capacity is not limited by its own capacity, so it has an excellent regulator characteristics. By the research on the STATCOM included wind power system, and combining with the approach of indirect current control, the simulation analyzed the effect of the STATCOM in the process of the transient fault controlling in the power system. The simulation result shows that the STATCOM has a big influence on maintaining the level of voltage and improving the transient stability of the power system.
