    摘 要:串补工程所涉设备繁多,在布置上与常规站有明显差别,其对电站电磁环境有较大影响。采用三维有限元分析计算方法,结合国外某 400 kV 串补工程,建立三相完整模型,对串补站近地工频电场分布及其影响因素展开研究。通过模型的对比分析表明:设计尺寸下的串补站近地电场分布满足限值要求,单一因素的变化仅对相关设备邻近区域的电场分布有显著影响;在一定范围内,平台及围栏越高,线路距离越近,近地电场分布所受影响越趋积极。

    Abstract: The series compensation project involves many kinds of equipment, which is obviously different from the conventional station in layout, and has a great influence on electromagnetic environment of the substation. In this paper, a three-phase complete model is established by using the three-dimensional finite element analysis calculation method and combined with a 400 kV series compensation project abroad, and the distribution of near-ground power frequency electric field and its influencing factors are studied. Through the comparative analysis of the models,it is shown that the near-ground electric field distribution of the series compensation station under the design size meets the limit requirements, and the change of a single factor only has a significant impact on the electric field distribution in the adjacent area of the related equipment; In a certain range, the higher the platform and fence, the closer the line distance, the more positive the influence of near-earth electric field distribution.
    Key words: series compensation equipment; power frequency electric field distribution; finite element method; three-phase complete model
