基于混频电源运行的模块化多电平矩阵式换流器阀段试验系统
Test System for Valve Section of Modular Multilevel Matrix Converter Based on Mixed-frequency Power Supply Operation
摘要
Abstract
Modular multilevel matrix converter(M3C)is currently the main power electronic equipment for frequency conversion in flexible low-frequency transmission systems.M3C contains 9 bridge-legs and is widely used in high-voltage and high-power situations with a large number of series modules,which poses the special testing requirements for the production of its equipment submodules.On the basis of analyzing the steady-state voltage and current of M3C bridge-legs,a pull-push operation test system is designed for several series bridge-leg submodules(valve sections),which can perform equivalent power operation tests to assist in the production and factory testing of M3C equipment.A control strategy for the pull-push test system is proposed,and a valve section push-push test system consisting of two sets of four series submodules is constructed and verified through relevant experiments.The experimental results show that the proposed test system can meet the equivalent power operation test of M3C bridge-leg series submodules,and does not require high power consumption from the power source.关键词
