摘要

无源电力滤波器存在以下问题:(1)源阻抗可能强烈影响滤波特性;(2)它可能引起串联谐振和/或并联谐振以扭曲电压。无源电力滤波器的这些缺点可以通过有源和无源电力滤波器的组合使用以及适当地协调它们的操作来改善。对非线性负载产生的谐波，用有源滤波器补偿变化频率分量，用无源滤波器补偿固定频率分量。这为非线性负载产生的不规则变频谐波电流在整个工作范围内提供了良好的谐波补偿。此外，这种安排抑制平行和串联共振。本文对所提出的混合电力滤波器的运行控制策略进行了分析和仿真。

Operation strategy of hybrid harmonic filter in demand-side system

The passive power filter has the following problems: (1) the source impedance may strongly affect the filtering characteristics; and (2) it may cause a series resonance and/or a parallel resonance to distort voltages. These disadvantages of the passive power filter can be improved by the combined use of active and passive power filters and by appropriately coordinating their operations. To harmonics generated by the nonlinear load, the varying frequency components are compensated by the active power filter and the fixed frequency components by the passive power filters of the proposed method. This provides a good harmonic compensation over the entire operation range for the irregularly varying frequency harmonic current generated by the nonlinear load. In addition, this arrangement suppresses parallel and series resonances. In this paper, an operation and control strategy for the proposed hybrid power filter is analyzed and simulated.
