| 摘 要： | 目的分析电力系统中静止同步补偿器(D-STATCOM)进行无功补偿的意义及其与传统无功补偿装置的区别。方法通过对其工作原理的分析、电流间接控制方法的使用以及不平衡负载补偿方法原理的介绍,可看出D-STATCOM的补偿性能优于传统的无功补偿器。结果通过对文中提到的控制策略的分析比较,确定了采用双变量协调控制的控制方式来提高动态补偿效果,同时提出了对不平衡负载电流补偿的新方法,该方法可以节省装置的硬件资源。结论D-STATCOM补偿器对用户电力的电能质量动态补偿和静态补偿效果比较好。

| Abstract: | Aim The significance of distribution static synchronous compensator(D-STATCOM) compensating reactive power in power system and the distinction between traditional reactive power compensator and D-STATCOM have been introduced.Methods The performance of D-STATCOM is superior to that of traditional reactive power compensator according to analyzing the working principle of D-STATCOM.Results By comparing the control scheme mentioned,we made the conclusion that bivariate coordinated control system would upgrade the dynamic compensating effectiveness of D-STATCOM.At the same time,the solution of compensating unbalance load current is proposed,which could save the hardware source of the service.Conclusion D-STATCOM has preferable transient performance and static performance. |
