| 摘 要： | 针对测向交叉定位法在对放电信号进行分析以获得放电源位置信息时,存在多放电源情况下大量的虚假定位问题,利用3个传感器阵列,采用基准线最小距离法来排除交叉定位中的虚假点:首先使用多重信号分类对多个局部放电源进行观测和计算,得到各个信号源的方位;然后利用基准线最小距离法去除交叉定位中的虚假点.仿真结果表明了该方法的有效性和实用性.

| Abstract: | How to remove the mendacious location during the direction-finding is the key problem in the location of discharge of sources.In this paper,three sensors and the base line least distance method were used to remove the mendacious locations in the cross-location.In the proposed method,firstly the observation and calculation of multi-local discharge sources by multiple classification(MUSIC) algorithm was adopt,and azimuth of each signal source was obtained.The mendacious location was removed by the base line l... |
