Simulation Study on Electromagnetic Environment of AC Double-circuit Transmission Lines in Heavy Icing Area
摘要
Abstract
With the increasing voltage levels and growing coverage of transmission lines,the problems of electromagnetic environment and icing become worse.However,less attention has been paid to the electromagnetic environment of transmission lines in icing condition.Therefore,a simulation analysis on the electromagnetic environment of 220 kV AC double-circuit transmission lines in heavy icing area is conducted in this study by means of the software SES-EnviroPlus.The effects of the parameters,such as phase distance,split number,conductor diameter,bundle interval and conductor height,on the electromagnetic environment are investigated,and the characteristics of the electromagnetic environments with and without icing condition are compared.The results show that among the four environmental parameters,only electric field intensity is beyond the limit.A conclusion is drawn that the electromagnetic environment becomes worse in icing area,but the effect rules of the parameters on the electromagnetic environment remain the same.In addition,some suggestions for the design of 220 kV AC double-circuit transmission line in heavy icing area are offered in respect of electromagnetic environment.关键词
