          摘 要:串補工程所涉設備繁多,在布置上與常規站有明顯差別,其對電站電磁環境有較大影響。采用三維有限元分析計算方法,結合國外某 400 kV 串補工程,建立三相完整模型,對串補站近地工頻電場分布及其影響因素展開研究。通過模型的對比分析表明:設計尺寸下的串補站近地電場分布滿足限值要求,單一因素的變化僅對相關設備鄰近區域的電場分布有顯著影響;在一定范圍內,平臺及圍欄越高,線路距離越近,近地電場分布所受影響越趨積極。
          關鍵詞: 串補裝置;工頻電場分布;有限元法;三相完整模型

          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
