摘　　要：本文提出了一种模拟电荷法和边界元法相结合的方法,将变电站内设备的影响考虑进去,可更加准确地确定变电站内工频电场分布,并且本文采用了合理简化剖分的方法,减少了冗长的叠加过程,在保证了计算精度的同时,大大缩短了计算时间,为变电站内工频电场计算提供了一种快速有效的方法。本文仿真结果与变电站实测结果基本一致,证明该方法能够用于变电站工频电场分布的预测。This paper used a hybrid technique combining the charge simulation（CSM） and boundary element method（BEM） to calculate the electric field.In this method,the influence of circuit breaker,insulating switch,tower and other elements in the substation is taken into account.In order to shorten computing time,this paper used the direct integration approach.The simulation results are basically consistent with the measured results and proved that the method can be used to forecast the power frequency electric field distribution in the substation.
