| 摘 要： | 电网电压不对称条件下配电网静止同步补偿器（DSTATCOM）采用传统检测方法提取的指令电流存在误差,导致其补偿性能变差.针对这个问题,研究了DSTATCOM的基本工作原理,提出一种新型指令电流检测方法,从指令电流检测、电流跟踪控制和直流侧电压稳定方面设计控制系统.一台10kVA的样机实验表明,DSTATCOM能够在电网电压不对称时对谐波和无功功率进行有效补偿.

| Abstract: | In the case of unsymmetrical grid voltage,there exist errors in the reference compensation current detected by traditional ip--iq method which affects the performance of DSTATCOM To overcome the drawback, this paper researchs the basic working principle of DSTATCOM, introduces a novel reference current detection method and then designs control system from reference current detection, current tracking control and DC voltage control. Results obtained by a 10kVA prototype experiment show that the DSTATCOM can compensate harmonic and reactive currents effectively under unsymmetrical grid votage. |
