摘要
本文提出一种基于超高频与超声波信号的变压器局部放电定位方法,该方法利用两种信号的时延计算出距离,再采用改进MUSIC算法对超声阵列信号进行测向,最终可确定放电源的几何空间位置。仿真结果表明该方法对局放源有良好的定位效果。
In this paper,a partial discharge location method of transformer based on UHF and ultrasonic signals is proposed.The distance is calculated by using the delay of the two signals,and then the direction fi nding of the received ultrasonic array signal is carried out by using the improved MUSIC algorithm.Finally,the geometric position of the discharge power supply can be determined.The simulation results show that the method has a good positioning effect on the local discharge source.
