摘要
为了提高静止无功发生器向电力系统输送无功功率的实时性与精确性,提出了一种基于数字信号处理(DSP)的电流间接控制方法,并利用这种方法设计了静止无功发生器的控制器.把采用该控制方法的静止无功发生器投入到一个出现故障的单机无穷大系统进行分析和研究.仿真结果表明,这种电流间接控制方法可以在系统出现故障后大约6 s内快速、有效地改善电力系统的暂态稳定性,效果良好.
In order to improve real-time performance and the accuracy of STATCOM, a method of current indirect control based on DSP is proposed and the controller is designed with this strategy. The property of control with STATCOM is analyzed and discussed with the example of STATCOM put into an infinite bus system with fault. The simulation results show that the method of current indirect control can improve the transient stability after the fault appeares within about 6 seconds and the effect is good.
