| 摘 要： | 在基于超高频和超声波相控接收原理的局部放电定位法基础上融入MUSIC算法,以达到对电力变压器气局部放电点的准确定位,并对其进行了仿真研究。基于超高频和超声波相控接收阵的局部放电定位法,可得出局部放电源的几何位置。但该方法不能区分一个波束宽度内的多个放电源,因此应用改进MUSIC算法对接收信号进行空间谱分析,完成变压器内一个及多个局放点的方位估计,并确定相近的多个信号源个数。

| Abstract: | The paper showed the MUSIC algorithm was integrated to the method of UHF and ultrasonic Reception Principle of Phase Array to the purpose of accurate location of power transformer partial discharge （PD）, and make a research on the simulation. The location method can lead to the positions of the PD dimensional position. But the method can not distinguish several PD in one beam width .So a Improved MUSIC algorithm was applied for Space Spectrum Analysis of received signal, DOA estimation of one or more PD in transducer would be finished, and confirm the close source number. |
