摘　　要：针对不平衡负荷电纳补偿原理的不足,采用不平衡负荷补偿电流的优化算法,并结合滑模变结构控制方法,以实现单相桥STATCOM对不平衡负荷的优化补偿。最后对该控制系统进行了计算机仿真,结果表明所采用的控制策略能够体现不平衡负荷补偿电流优化算法的优越性,并且使受控系统具有较好的动态性能和稳态性能,对负载不平衡的变化适应能力强。Aiming at the shortages of unbalanced load compensation of admittances（L or C） principle,the optimization algorithm about current compensation of three-phase unbalanced load is adopted,and then it combines with sliding mode variable structure control theory to achieve the compensation optimization of unbalanced load by the single-phase bridge STATCOM.At last,the computer simulation for the control system is carried out,and the simulation results verify that the proposed control strategy reflects the superiority of compensation optimization to unbalanced load,and the controlled system has a better dynamic and steady quality,moreover,a good adaptive performance to reactive changes of the unbalanced load.
