摘要
针对电网中存在分数次谐波的情况,本文简单分析附加小电感的并联混合式有源滤波器的拓扑结构,采用电流复合控制策略时的补偿性能。在此基础上主要分析了含分数次谐波下混合式滤波器的补偿影响。提出附加单调谐支路、判断是否含有分数次谐波和直流侧电压稳定等相应解决方案。最后利用电力系统仿真软件PSCAD对所提方案进行了仿真研究,证明了所提方案的正确性。本文所提解决方案对进一步研究分数次谐波的影响有一定的借鉴价值。
According to the situation of non-integer harmonics in power system, taking a topology of shunt hybrid active power filter （HAPF） with a little inductance as example, this paper simply analyzes the performance of harmonic compensation of HAPF with current compound control. Based on this, the paper mainly proposes the influences of HAPF with non-integer harmonics. Then the scheme including adding single tuning road, judging whether it contains non-integer harmonic and the stability of DC voltage is given. At last, the experimental results used by PSCAD soft-ware show the validity of the method. The conclusion is helpful to further research on noninteger harmonics for HAPF in power system.
