摘　　要：为了实现最优路线规划,促进架空地线节能降损,研究基于多目标进化算法的输电线路架空地线节能接地技术。以架空地线路线遭受地质灾害风险最低、运行安全系数最高为目标,搭建输电线路架空地线路线优化模型;采用多目标进化算法求解模型,获取路线优化方案;依据实际地质情况选择单回或多回线路架空地线节能接地技术。实验结果表明:采用所提技术可获取符合目标函数及约束条件的输电线路架空地线路线优化方案,选取节能接地方式为单回线路两根架空地线,每段架空地线的节距为6.4 km,接地点选在各段地线的中间点,该接地方式较上一年度电能损耗下降60%~69%,节能效果突出。In order to realize the optimal route planning and promote the energy-saving and loss reduction of overhead ground wire,the energy-saving grounding technology of overhead ground wire of transmission line based on multi-objective evolutionary algorithm is studied.Aiming at the lowest risk of geological disasters and the highest operation safety factor of overhead ground wire route,an optimization model of overhead ground wire route of transmission line is established.The multi-objective evolutionary algorithm is used to solve the model and obtain the route optimization scheme.The energysaving grounding technology of single circuit or multi circuit overhead ground wire is selected according to the actual geological conditions.The experimental results show that the proposed technology can obtain the optimization scheme of overhead ground wire route of transmission line in line with the objective function and constraints.The energy-saving grounding mode is selected as two overhead ground wires of single circuit line,the pitch of each section of overhead ground wire is 6.4 km,and the grounding point is selected at the middle point of each section of ground wire.Compared with the previous year,the power loss of this grounding mode is reduced by 60%~69%,and the energy-saving effect is outstanding.
