Robust Fault Isolation and Restoration for Distribution Systems
摘要
Abstract
To realize the reliable fault isolation and restoration in case of mis-reporting or failed-reporting of fault information for distribution systems, a Bayes analysis based approach is proposed. The correlation of fault information of various phases is utilized to commit the robust fault location. As for the overhead feeder with permanent fault, the fault information during the reclosing process is merged to improve the result of fault location. In case of mistaken fault location and isolation, the fault information during the restoration process is merged for fault relocation and correction control is performed. Based on above-mentioned priciples, a flow chart of robust fault isolation and restoration is proposed and described indetail by three real cases to which the proposed method is applied. Application results show that the proposed method possesses fault tolerant ability under mis-reporting or failed-reporting of fault information, therefore it is favorable to restore power supply for healthy sections as much as possible.关键词
