Optimization Method of Active Rush-Repair for Distribution Network Based on the “Marketing-Distribution-Dispatch” Integrated Rush-repair Network

Abstract

at present, the rush-repair schedule of distribution network becomes an important factor which affects the reliability of power grid.The four problems that affect the process of rush-repair are as follows: 1) Failure to receive complete failure information; 2) Fault diagnosis depending on personal experience; 3) The process of dispatching is cumbersome; 4) Lack of experience summary after rush-repair. The above factors affect the fault judgment of dispatchers, slowing down the command response speed and prolonging the rush-repair progress and outage time of power failure.To solve the above problems, this research is put forward. An active rush-repair strategy based on association relation method is proposed. An intelligent fault diagnosis based on BP algorithm is proposed. To optimize the process of dispatching command, "Marketing-Distribution-Dispatch-Repair" rush-repair database is proposed. The case analysis shows that the research plays a positive role in the rapid judgment of fault causes, the acceleration of rush-repair command speed and the shortening of fault outage time. This research will help to improve the power supply reliability of power grid.
