要約(日本語): This paper presents a method for locating the position of partial discharge (PD), which occurs on distribution line, by estimating the direction-of-arrival (DOA) of electromagnetic (EM) waves. The DOAs (azimuth and elevation angles) are estimated by using the two-dimensional improved coherent signal subspace method (2D I-CSM). The position of PD can be located as the intersection of DOAs estimated at two points. It is shown that the proposed method is useful for locating the position of single PD.
