导储能系统用电流型变流器控制超设计和实验

Design and Experiments of Current Source Converters Power Control for Superconducting Magnetic Energy Storage System

本文推导了SPWM控制下的电流型变流器的有功功率、无功功率和调制比、相位角的关系,设计了一种基于瞬时功率理论的电流型变流器功率闭环控制方法。结合变流器实验样机,对超导储能系统用电流型变流器四象限功率控制方法进行了验证,给出了试验波形。

The paper introduces the structure of Superconducling Magnetic Energy Storage System （SMES）, analyses the theory of Cun＇ent source converter and gives the design of the converter for SMES. A 23kMA prototype multi-modular converter has been developed. At last the paper gives experimental results of the above practical four-module current source converter. The research has shown that it can control active power and reactive power independently and rapidly.
