针对非线性负载引起的谐波污染问题,提出一种不对称拓扑的单调谐混合有源滤波器(Hybrid Active Power Filter,HAPF)。该不对称拓扑结构包含一个三相电压型变流器与两相LC式无源滤波器。通过分析新拓扑的工作原理和特点,构建滤波等效电路,利用含无源滤波器的两相电流构造不对称第三相电流的控制量,实现对电网三相谐波电流的有效抑制和滤波器直流电压的控制,直流侧电压采用比例积分(Proportional Integral,PI)控制其稳定。利用仿真和实验对拓扑电路及控制策略进行验证,实验结果验证了所提出的拓扑结构及控制方案的可行性。
To address the harmonic pollution caused by nonlinear loads
a single-tuned hybrid active power filter (HAPF) with asymmetric topology is proposed
which consists of a three-phase voltage converter and a two-phase LC passive filter. By analyzing the operating principle and characteristics of the new topology
a filtering equivalent circuit is designed. By analyzing the working principle and characteristics of the new topology
a filter equivalent circuit is constructed. The two-phase current with passive filter is used to construct the control quantity of asymmetric third-phase current
which can effectively suppress the three phase harmonic current of the power grid and control the DC-link voltage of the filter. The DC-link voltage is stabilized by Proportional Integral (PI) . The topology circuit and control strategy are tested by conducting simulations and experiments
and the experimental results validate the feasibility of the proposed topology and control scheme.
