摘要

针对大容量非线性负载的谐波补偿问题

提出了一种模块化有源电力滤波器并联组合系统。研究了多模块并联组合系统的结构及其工作原理

在此基础上建立小信号模型加以分析

并引入模块容量差异化情况下的控制策略作为对比

提出了相同容量模块间基于均流系数实时更新的均流控制及冗余控制策略。各个模块内则采用数字比例-积分(PI)和重复控制构成的复合电流控制策略

保证系统的稳态补偿精度和动态响应速度。最后

搭建了单台容量为50 kVA的双模块有源电力滤波器并联组合系统

对比了不同模块间控制策略及不同模块内控制策略的补偿效果

实验结果证明了所提出的控制策略的可行性和有效性。

Abstract

For the harmonic of large capacity nonlinear load

a parallel combinatorial system of modular active power filter is proposed and its system structure and operating principle are researched. Based on this

the corresponding small signal model is set up and a control strategy in the case of different module capacities is introduced for comparison. Then an average current control and redundancy control strategy is put forward. In order to guarantee the steady and dynamic performance

a compound control strategy including digital proportional-integral control and repetitive control is adopted. Finally

a device including two modular 50 kVA active power filters is constructed and the effects of different control strategies among modules and different control strategies inside modules are compared. The feasibility and efficiency of the proposed control strategy is validated by experimental results. This work is supported by National Natural Science Foundation of China (No. 51177147).
