中文摘要:

近年来随着我国电网的飞速发展，电磁环境问题引起了社会的广泛关注，特别是变电站的工频电场问题越来越受到人们的重视。本文基于模拟电荷法提出了一种改进的算法，通过对变电站进行整体建模，仿真计算离地1.5m处的电场分布。通过与CDEGS软件仿真结果及现场实测数据的比较，验证了本文算法的正确性。最后对某220kV变电站进行计算分析，讨论了设备高度、进出线相间距和相序排列对变电站工频电场分布影响，结果表明提高导线对地高度、减小相间距、合理的线路相序排列都能降低变电站内的电场强度，为变电站工频电场强度的分析与设计提供了参考。

英文摘要:

The electromagnetic environment has gained much interest in recent years， especially power frequency electromagnetic field， as the development of domestic power grid. As for such an issue， a kind of improved algorithm based on charge simulation method is proposed in this paper， with which the holistic modeling is implemented and the electric field distribution at the height of 1.5m is identified via programming calculation. And the algorithm is proved to be of validity by comparison with simulation of CDEGS software. Eventually， the specific electric field of a 220kV substation distribution is calculated meanwhile three influencing factors are studied， which can be utilized as credible guidance for substation construction.
