500kV同塔双回紧凑型输电线路电磁环境分析
Analysis on Electromagnetic Environment of 500 kV Compact Transmission Line with Double Circuits on the Same Tower
摘要
Abstract
To effectively analyze the electromagnetic environment of 500 kV compact transmission lines with double circuits on the same tower,the charge simulation method and the moment method are combined to calculate the electric field,Biot-SaUart principle is employed to calculate the magnetic field,and the excitation function method as well as the BPA-recommended prediction method is adopted to calculate the audible noise and radio interference.As a result,the electric and magnetic field strength,audible noise and radio interference of the 500 kV compact transmission line with different sub-conduetor types,phase spacing and the lowest height of lower phase conductor are obtained and analyzed.Results show that in order to meet the requirements for the electromagnetic environment under the transmission line,the smallest height of the lower phase conductor adjacent to houses ought to be not less than 16 m,in public area and across-road area the smallest height of the lower phase conductor ought to be not less than 12 m,the smallest height of the lower phase conductor across farmland ought to be not less than 10 m,and the spacing of phase conductors is recommended 6.7 m.关键词
