摘　　要：为了解决中短波发射台供配电系统的故障问题,提高系统运行的稳定性,提出中短波发射台供配电故障定位方法。在中短波发射台供配电系统中安装感知传感器,并利用该设备获取供配电信息,分别从数据、特征和决策3个层级实现信息融合。将直接故障事件和潮流配电量设置为判据,确定供配电故障识别结果,综合配电侧故障的故障类型和故障线路等信息,得出最终的中短波发射台供配电故障定位结果。为了验证设计的中短波发射台供配电故障定位方法的综合性能,进行实验,结果表明,该方法的定位结果更精准、耗时更短,验证了该方法的可行性。To solve the power supply fault problem and improve the system operation stability of the medium-and shortwave transmitting station,a new fault location method is proposed in this paper.The sensor is installed in the power supply and distribution system of the station to obtain the power supply and distribution information.Information fusion is realized from three levels of data,characteristics and decision.Direct fault events and power flow distribution capacity are set as criteria to determine the fault identification results of power supply and distribution,and the final fault location results of power supply and distribution are obtained by integrating the fault types and fault lines.An experiment is conducted to verify the comprehensive performance of the designed fault location method for power supply and distribution,and the results show that the location results by this method are more accurate and the time consumption is shorter,which has verified the feasibility of this method.
