分布式电源条件下故障定位与快速恢复供电技术

Research on Fault Location and Rapid Power Restoration Technology under Distributed Power Conditions

为解决配电网络接入分布式电源后,潮流变为双向流动,无法使用传统馈线自动化技术进行故障处理的问题,提出在分布式电源条件下定位故障区域的简单方法,并提出分布式电源因故障切除后,非故障区域快速恢复供电的计算方法。通过某地区配电环网算例,证明了两种方法的正确性及实用性。

To solve the problem of two-way flow of the trend connected with distributed power and cannot use the tradi- tional feeder automation technology for troubleshooting, a simple method is proposed to locate the fault area in the distributed generation conditions. When distributed power causes failure after resection, a calculation method of non-fault zone quickly re- store power is proposed. Through an example of regional power distribution ring network, the correctness and practicability of both methods are proved.
