Transformer PD Location Data Error Analysis and Analytical-gridding Algorithm

本文研究了局部放电定位的误差空间分布特性,提出了局部放电定位方程组的解析求解方法,减少了计算时间。以解析算法求解结果的实部为中心进行网格搜索,获得更加精确的局部放电实数坐标。

In this paper, the error spatial distribution characteristics of partial discharge lo calization are researched, and the analytical solution method of partial discharge local ization equations is proposed, which reduces the calculation time. The grid search is centered on the real part of the analytical algorithm to obtain more accurate partial dis- charge real coordinates.
