3) fault direction
故障方向
1.
Based on the character that some bus nodes can judge the fault direction by current measurement in DG system, this paper presents an adaptive searching algorithm for dividing relevant fault area.
结合多DG接入下的配电网部分母线节点可以通过电流量来判断故障方向的特点,提出了一种具有较强自适应性的故障相关区域划分方法,而这种分布式的、缩小上传保护电流数据范围的算法减少了保护数据在信道上排队避让的时间,保护装置只需得到故障相关区域内的故障电流数据即可正确动作,实现了保护的选择性及速动性,降低了对通信系统的依赖性。
