摘要

预装式变电站一般安装在公众易于接近的地点。为确保人身安全，需要评估预装式变电站对外辐射的工频电场强度与工频磁通密度。与现场测量相比，基于计算电磁学的仿真方法具有更高的评估效率。文中使用有限元法对10 kV户外变电站进行电磁环境仿真分析，并将仿真结果与现场实测数据进行比对，仿真结果与实测数据一致性较好，验证了有限元法仿真计算的准确性。

Abstract

Prefabricated substations are generally installed in locations which are easily accessible to the public. For personnel safety

it is necessary to assess the power frequency electric field strength and power frequency magnetic flux density radiated externally by the prefabricated substation. Compared with on-site measurements

the simulation methods based on computational electromagnetics have higher assessment efficiency. The finite element method is used in this paper to perform electromagnetic environment simulation and analysis of 10 kV outdoor substation. The simulation result is compared with the measurement data at site with a good agreement

which verifies the accuracy of the simulation calculation of finite element method.
