    摘 要:針對電氣化鐵路牽引變電站存在無功波動大、功率因數低的問題,提出了應用晶閘管控制高阻抗變壓器(TCT)型靜止無功補償(SVC)進行動態無功補償的解決方法。分析了TCT型SVC的補償原理,以某鐵路牽引變電站動態無功補償為例,說明TCT型SVC投運后能快速跟蹤負荷無功變化需求,功率因數明顯提高,電壓穩定性得到改善,并取得良好的經濟效果。
    關鍵詞:晶閘管控制高阻抗變壓器(TCT);靜止無功補償(SVC);鐵路牽引變電站;功率因數;動態無功補償

    Abstract: For the existing problem of great reactive power fluctuation and low power factor in the electrified railway traction substation, this paper proposed to use the thyristor controlled high impedance transformer (TCT) type static var compensation (SVC) to compensate reactive power dynamically. The compensation principle of TCT type SVC was analyzed. The dynamic SVC of certain railway traction substation shows that TCT type SVC can fast track the load reactive power, the power factor is improved obviously, the voltage stability is improved and the economic effect is well achieved.
    Key words: thyristor controlled high impedance transformer; static var compensation; railway traction substation; power factor; dynamic reactive power compensation
