同塔四回路输电线的三维空间电磁干扰
Investigation on the Electromagnetic Interference of Four-circuit Transmission Lines
摘要
Abstract
In order to solve the growing urban grid load and the growing tension in the land resources, more and more four-circuits transmission lines have been built in China. In the paper, the calculation of electric field and magnetic field considering the influence caused by the sag is investigated. To a- void the shortcoming in current calculation method, the method to analyze the influence caused by the transmission lines sag is presented in the paper. A 110 four-circuits transmission lines in Chongqing was taken as an example, the electric field and magnetic field in 2D space and 3D space were calcu- lated respectively, and comparison was conducted. Results indicate that the electric and magnetic fields obtained in 2D space have an error of 11.2% for electric field, and 7.1% for magnetic field.In addition, because of the change of the parameters of multi-circuit transmission line, the interfer- ence between different loops in one tower is analyzed, and results indicate that the interference be- tween different loops should be calculated for line accident.关键词
