基于受控哈密顿系统模型的含间谐波的有源电力滤波器电流跟踪策略研究

摘要

The Port Controlled Hamiltonan( PCH) system model of three-phase three line shunt Active Power Filters ( APF) is derived.Based on the model and the characteristic of PCH system, the outer current tracking strategy of three-phase three line shunt active power filters is designed using the passive theory, which is also proved the stability of this strategy.The problem of tracking complex current with inter harmonics by three-phase three line shunt active power filters can be achieved by this strategy.At last, the simulation platform of system is build by matlab/simulink, which verifies that inter harmonics current can be tracked by this strategy.%推导了三相三线并联型有源电力滤波器( APF )的受控哈密顿系统( PCH )模型,基于该模型以及受控哈密顿系统的特点,利用无源性理论设计了三相三线并联型有源电力滤波器的外层电流跟踪策略,并且证明了该控制策略的稳定性. 该控制策略能够实现三相三线并联型有源电力滤波器对含间谐波信号的复杂电流跟踪问题,最后通过Mat-lab/Simulink搭建了系统的仿真平台,仿真结果说明该控制策略确实能实现间谐波电流的跟踪.
