摘要

无变压器并联混合有源电力滤波器(TLS - HAPF)由于其有源部分几乎不承担基波电压，可用于中压配电系统中进行谐波和无功补偿。此外，TLS-HAPF还可以抑制电网中现有无源无功补偿装置与线路电感之间的串并联谐振。基于电网侧谐波检测和电容电流反馈，提出了一种新的tlshapf控制策略，可同时补偿非线性负载谐波和并联功率因数校正电容器与线路电感之间的阻尼谐振。仿真结果表明，所提出的控制策略可以提高滤波性能。

A New Control Method for Harmonic Compensating and Resonance Damping in Hybrid Filter

Transformerless Shunt Hybrid Active Power Filter (TLS - HAPF), benefiting from its active part undertake almost no fundamental voltage, can be used in medium-voltage power distribution system for harmonic and reactive power compensation. Besides, the TLS-HAPF can also damp out the series/parallel resonance between the existing passive reactive compensation device and line inductance in the power grid. Based on the grid-side harmonic detection and the capacitve current feedback, this paper proposes a novel control strategy for TLS - HAPF to compensate harmonics from nonlinear loads and damp resonance between shunt power-factor-correction capacitors and line inductance simultaneously. Simulation results have confirmed that the filtering performance can be improved by the proposed control strategy.
