Abstract

本发明涉及电力系统中的静态同步无功补偿装置及控制方法,该补偿装置包括基于全控型电力电子器件的电压型逆变器、连接逆变器和电力系统的容性阻抗以及控制装置,所述容性阻抗包括一个为了补偿无功而设定的电容和一个为了抑制电流波动而加的电感。由于采用了容性阻抗连接,逆变器直流部分的电压大大降低,减小了无功补偿的成本和开关损耗,该控制方法包括:首先计算三相的瞬时无功,再由瞬时无功计算出每相需要的无功补偿电流,根据补偿电流的基频有效值和容性阻抗计算逆变器补偿基频无功所需输出的基波电压,动态补偿无功。由于各相无功功率独立计算从而实现了动态的不对称无功补偿,并且在三相三线和三线四线系统中都适用。
