摘　　要：传统机械式有载分接开关存在切换过程中产生电弧、动作速度慢等问题。为解决这一问题,需研究新型无弧有载调压分接开关。本文在PSACD/EMTDC中建立机械式有载分接开关和电力电子式有载分接开关模型,对两者的调压过程进行分析比较,计算出两种方式下有载调压过程中的能量损耗,为新型有载分接开关的研究提供了参考。The traditionally mechanical on-load tap-changer exist many problems such as producing electric arc on switching process, slow movement speed etc. A new no arc on-load tap-changer is needed to developed to solve the above problems. Mechanical on-load tap-changer and power electronic type on-load tap-changer PSCAD model are established in this paper. The energy loss of those two type on-load tap-changer is calculated from simulation which provides reference for further development of on-load tap-changer.
