| 摘 要： | 在三相四线制条件下,采用三角形联结和星形联结的补偿网络,对不平衡电流的负序和零序分量进行了补偿,并将功率因数提高到1,而且使补偿电流最小。同时,对补偿公式进行了优化,简化了动态无功补偿的采样。最后通过仿真,验证了本文的正确性。

| Abstract: | For three-phase four-wire system,the delta-connection and star-connection compensation devices have been adopt to balance negative sequence and zero sequence current.The power factor has been improved to 1 and the three-phase compensation currents are smallest.The reactive power compensation formula is optimized,which make the sampling for dynamic reactive power compensation simple.At last,MATLAB simulation demonstrates the theory is correct. |
