电气化铁路牵引供电变相原理研究综述

General Descriptions on Phase Transformation of Traction Power Supply for Electrified Railway

为探索解决电气化铁路牵引供电系统中存在的负序、无功、谐波、电分相等问题,基于相位变换方式,以交流电机作为研究起点,提出了一变一、二变一、三变一交流变相电机的概念及模型,并以变相电机研究为基础提出XT接线结构的变电所模型及其供电系统结构。

For discussion and settlement of problems of negative sequence,reactive power,harmonics and neutral section existed in traction power supply system of electrified railway,depending on the phase transformation route,and with the study of AC electric motor as the starting point,a concept and models for AC phase transformation electric motor transformed from one phase-to-one phase,two phase-to-one phase and three phase-to-one phase have been put forward,and with the study of phase transformed electric motor as a basis,the substation model with XT wiring and its power supply system structure have been proposed as well.
