    摘 要:串補(bǔ)工程所涉設(shè)備繁多,在布置上與常規(guī)站有明顯差別,其對(duì)電站電磁環(huán)境有較大影響。采用三維有限元分析計(jì)算方法,結(jié)合國(guó)外某 400 kV 串補(bǔ)工程,建立三相完整模型,對(duì)串補(bǔ)站近地工頻電場(chǎng)分布及其影響因素展開研究。通過模型的對(duì)比分析表明:設(shè)計(jì)尺寸下的串補(bǔ)站近地電場(chǎng)分布滿足限值要求,單一因素的變化僅對(duì)相關(guān)設(shè)備鄰近區(qū)域的電場(chǎng)分布有顯著影響;在一定范圍內(nèi),平臺(tái)及圍欄越高,線路距離越近,近地電場(chǎng)分布所受影響越趨積極。

    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
