摘要：

Fault location, isolation and service restoration (FLISR) in the feeder automation (FA) is usually used to improve the power supply reliability and provide outage management. The FLISR failure mechanism was analyzed based on the programmed sequences and intervals of the feeder terminal units (FTUs), master station of distribution automation system (MS-DAS) and the communication channel. Zero-failure reliability demonstration test was used to evaluate the FLISR reliability. Different from traditional evaluation in the pass/fail verification, normalized FLISR reliability assessed value was identified according to several FLISR test result scenarios, which include normal operation, isolation area expansion, whole system failure and fault area expansion scenarios. The final FLISR reliability was evaluated based on the statistical assessed value data of each test samples. The case study helps to prove the effectiveness of the proposed FLISR reliability assessment method. The research results could be used to evaluate the FLISR practical value in the field. © 2020, Politechnica University of Bucharest. All rights reserved.
