Analysis of Z/ Y Wire and Phases of Grounding Transformer

接地变压器Z/Y接线与相位的分析

The Y connection and delta connection of transformer in DVR is simulated with Matlab and the three-phase four-wire structure with Y connection is used in the experiment, which can compensate zero voltage component of source voltage by approved SVPWM algorithm.

分别对变压器不同的连接方法进行了Matlab系统仿真，并对变压器星形连接的三相四线结构和改进的SVPWM控制方法作了实验，解决了系统中存在电压零序分量问题。

Based of the experience in the technical transformation engineering, the two winding methods for Z/ Y wire of grounding transformer are discussed.

基于技改工程的经验，探讨接地变压器Z/Y接线的两种绕线形式，分析了该变压器相位变化的原因。
