摘　　要：我国西北地区因冬季寒冷,对取暖的需求更大,因此电锅炉的使用越加频繁,但是输电走廊用地越来越紧缺。基于这种情况,提出对西北地区交直流线路进行优化,使其可以直接输入电锅炉。为了解决输电线路的混合电场问题,对混合电场的各种参数和影响条件进行分析,建立模型进行测量电场数据。实验数据选取西北地区近几年冬季的气温,基于气温、离子迁移率、起晕场强等分析各种情况下线路的情况,计算冬季并行线路混合电场的分布情况和冬季并行路线合成电场的数据,证明了研究的可行性,以及交流线路会对直流合成电场产生一定的屏蔽作用。The northwest region has a greater demand for heating due to the cold winter,so the use of electric boilers is more frequent,but the land for power transmission corridors is more and more scarce.Therefore,this paper proposes to optimize the AC and DC lines in Northwest China so that they can be directly input to electric boilers.In order to solve the problem of the hybrid electric field of the transmission line,various parameters and influence conditions of the hybrid electric field are analyzed,and a model is established to measure the electric field data.The experimental data select the temperature in winter in the northwest region in recent years,and temperature,ion mobility,and halo field strength,etc are used to analyze the line situation.The distribution of the hybrid electric field of the parallel lines in winter and the data of the combined electric field of the parallel lines in winter are calculated by experiments,which proves the feasibility of the study and the AC line will have a shielding effect on the DC synthetic electric field.
