摘要
针对变电站内母线周围存在的自由电荷与大地感应电荷产生的电场强度分布的计算问题,以及站内主要设备的表面自由电荷、极化电荷产生的电场分布的计算问题,提出一种将三维模拟电荷法和边界元法相结合的计算方式。以500kV变电站为例,通过这2种方法对变电站周围工作区域的工频电场进行计算,为特高压变电站的设计提供电场分布的估算方法。
This paper uses three-dimensional charge simulation method to calculate the distribution of free charge in substation bus and electric intensity generated by the earth induced charge,and uses the boundary element method to calculate the field distribution of substation equipment surface free charge and polarization charge.Taking 500kV substation for an example,this paper calculates the power frequency electric field in the work area around,provides a method for estimating frequency electric field distribution in UHV substation design.
