Abstract
In this paper, a partial discharge location model of power transformer is proposed, and the solution method of partial discharge fault location equation is studied. The location accuracy analysis considering time difference, sensor position and sound velocity measurement error satisfying different probability distributions is also presented. A new location algorithm based on grid search is proposed, the algorithm has high positioning accuracy, but its calculation is too large. Through the simulation analysis of MATLAB programming, compared with the previous algorithm, the improvement measures for the new algorithm are proposed.
