摘要

研究了H桥级联5电平结构的电压质量调节装置，在分析装置工作原理的基础上，对系统中出现的典型电压质量问题提出了多目标控制策略，能综合解决电压暂降、谐波等问题。同时，在负荷侧发生短路故障时，还能实现限制短路电流的控制目标。基于PSCAD/EMTDC仿真软件建立了多目标电压质量调节器的仿真模型，仿真结果验证了所提出的主电路拓扑和控制策略的正确性和有效性。

Abstract

A new type of voltage quality conditioner with 5-level H bridge cascaded multilevel connection is studied. On the basis of working principle， a multi-objective control strategy is proposed which can resolve the typical power quality problems， such as voltage sag， voltage swell， and harmonic. The short circuit current can also be limited on the load side. Simulation results based on PSCAD/EMTDC show that the main circuit topology of voltage quality conditioner is correct and the multi-objective control strategy is valid.
