利用电力弹簧消除三相不平衡系统中负序和零序电流的综合分析与控制策略

This paper presents a general analysis and a control strategy that enables electric springs (ES) to mitigate the negative-sequence and zero-sequence currents in unbalanced three-phase power systems. The analysis indicates that under certain load conditions, power balance can be restored without the need for active power from the ES. Outside such conditions, the theory can pinpoint the precise oper...
