The accurate calculation of electric field intensity under transmission lines is more and important with the expansion high voltage engineering, which largely determines site selection design projects. In order to get results, a methodology charge simulation method (CSM) combined an intelligent optimization algorithm for 3D model proposed in this paper. Three key points are emphasized special mention optimized (OCSM). First, number sub-segments on finite length conductor, position simulating set sub-segment taken as parameters unified calculation. Secondly, fitness function constructed by two values, relative error error. Thirdly, element (FEM) was used obtain intensities, compared results algorithm. A case carried out 220 kV lines, verify effectiveness OCSM solves parameter problem CSM computational model, considers physical shape wire span, has advantages strong global search ability higher accuracy.
