摘要
配电网静止同步补偿器(D-STATCOM)是一种重要的电能质量校正设备,控制系统是它的关键组成部分,直接影响了D-STATCOM的动态补偿效果。基于PSCAD搭建了改进双闭环控制系统下的D-STATCOM仿真模型,省去了交流电压外环,在简化了控制系统的同时,保证了其补偿性能。仿真结果表明,所提出的控制策略是可行的,具有良好的动态补偿效果。
Distribution Static Synchronous Compensator ( D-STATCOM ) is an important power quality correction device, the control system is a key component of its direct impact on the dynamic compensation effect of D-STATCOM. Based on PSCAD build simulation models to improve the D-STATCOM under the dual-loop control system, eliminating the need for an AC voltage of the outer ring, at the same time simplifying the control system to ensure that its compensation performance. Simulation results show that the proposed control strategy is feasible and has good dynamic compensation effect.
