摘　　要： 设计了一套能有效判断电网复电后低压脱扣器重合闸情况的智能分析系统,以进行配网管理。利用计量自动化系统的测量功能,对配电网用户端断电和复电后的电流、电压变化进行实时监测,通过低压脱扣器在供电端复电后的工作状态分析,从而得出重合闸结果的准确判断。所开发的系统能够有效解决低压脱扣器在运行中存在的不利因素,为配网管理提供辅助参考依据,便于为客户提供可靠的供电信息,同时减少运行维护人员的重合闸工作量。通过具体案例分析,证明了本设计能较为准确地判断重合闸是否成功。 This paper designed an intelligent analysis system to get an accurate judgment of reclosing conditions of low vohage release device for distribution network management. Firstly, the working state of low voltage release after energization was analyzed by the measurement data of recovery voltage and current on the basic function of metering automation system. Then the designed software could judge whether the low voltage release device was reclosed successfully. And the designed system can solve the disadvantages of low voltage release operation on the power system and provide assisted foundation for distribution management, as well as reduce the workload for electric maintenance personnel. The validity of the software and the system was verified by the applications.
