phase-shifting autotransformer

The analysis of zero phase sequence differential protection for 750kV single-phase autotransformer;

750kV单相自耦变压器零序差动保护分析

A novel three-phase VSG is built by three-phase autotransformer and IGBT based bidirectional switch,can easily control the types of voltage sags,sag duration,sag depth and sag phase.

基于三相自耦变压器和由可控器件IGBT构成的双向开关实现的新型三相VSG,可以方便地控制跌落类型、跌落持续时间、跌落深度和跌落相位。
