摘　　要：在特高压交流变电站设计过程中,确定变电站空间电场尤其是设备附近电场的分布是相当重要的。针对变电站附近设备电场分布的复杂性,提出了三维边界元法对荆门1 000 k V变电站设备附近电场进行模拟研究,推导了三维空间合成电场极值的计算公式,并通过ANSYS仿真软件建立相应的仿真模型,对此方法进行验证,其理论计算结果与仿真结果基本一致,证明了该算法的正确性和有效性。In the process of UHV substations design, it is very important to determine the distribution of space electric field especially near the substation equipment. For the complexity of the electric field distribution near the substation equipment, the three-dimensional boundary element method is proposed for Jingmen 1 000 kV substation equipment to simulate the electric field research, the formula of the extremum of three-dimensional synthetic electric field is de- duced, and the corresponding simulation model is established through the ANSYS simulation software, for validation of this method, the theoretical calculation results and simulation results are basically identical, which proves the correctness and validity of the algorithm.
