- To study the influence of woods on electric field distribution of 500kV EHV Transmission lines, the Solidworks software was applied to create the simplified model of 500kV transmission lines, and the ANSYS software based on finite-element method was applied to calculate space electric field intensity of transmission lines. This paper chooses the electric field intensity of transmission lines and span central cross section as the research object. The calculation result shows that the maximum electric field intensity is about 1808v/m without woods and 1916v/m with 12m high woods and 2055v/m with 16m high woods in the middle of the span cross section 20 meters high above the ground. Woods around transmission lines can distort the space electric field of lines, and the higher of woods, the larger of the maximum of electric field over the woods. And using the method of unmanned aerial vehicle (uav) carrying measuring instruments to measure the cases with woods and without wood, respectively, and compare which with the calculation results to find that results of analysis are in agreement with the experimental datas basicly.This paper studies the space electric field intensity distribution of transmission lines under different height and location of woods, such can provide preference for reasonable erection of 500kV EHV transmission lines.
