以分布式同步串联补偿器为研究对象,以补偿电压的反馈控制为研究问题,深入研究了比例谐振控制策略在补偿电压控制中的应用。针对分布式同步串联补偿器的特点,以补偿电压跟踪误差的时域解析表达式为基础,探索了补偿电压控制器参数的设计方法。实验结果证明:应用比例谐振控制策略能够保证分布式同步串联补偿器的安全稳定运行,获得高精度的补偿电压。

In this paper,the application of proportional resonance control strategy on compensation voltage control is studied deeply with distributed synchronous series compensator as study object and the feedback control of compensation voltage as the study subject.In view of the features of distributed synchronous se-ries compensator,the time domain analytical expression the tracking error of compensation voltage is taken as the base to explore the design method of parameters of the compensation voltage controller.It is shown by the experimental result that use of proportional resonance control strategy can assure safe and stable op-eration of the distributed synchronous series compensator and obtain high precision compensation voltage.
