基于有限元法的±500 kV同塔双回线路电磁环境仿真计算
Simulation calculation of electromagnetic environment of ±500 kV double-circuit transmission line based on finite element method
摘要
Abstract
In order to study the influence of electromagnetic environment of ±500 kV double-circuit transmission line on live working , and provide the theoretical and numerical simulation studies of safety protection of live working , this paper takes the Z101 line tower of ±500 kV double-circuit transmission line as the research object , and establishes a three-dimensional model of the line tower with the mixed modeling techniques based on COMSOL and Soild Works .Ac-cording to the six different topical live working positions , the study of simulation is carried out towards the electric field and potential distribution of Z 101 line tower by using COMSOL .The results show that the potential difference of NO .5 position is the maximum, and the potential differences of all the other positions except No .4 and No.5 are similar, be-sides, the maximum electric field strength of human organs apears on the neck and limbs , and the electric field strength of human organs of No .5 position is the strongest , which generally exceeds the limit value of safety operation .There-fore, the worker should wear screen clothes and make other safety precaution efforts before live working in the double -circuit DC transmission line , and the results of this paper could provide the technical reference of other projects .关键词
