首发时间:2009-02-20
摘要:近年来,随着大功率电力电子器件等非线性负载的大量应用,给电网带来了严重的谐波污染。在谐波治理污染问题上,无源的交流调谐滤波器成为电力系统中最普遍的谐波抑制设备。但这种调谐滤波器在使用中也存在着如失谐、过流、不能进行无功优化等缺点,文中提出了基于电抗率可调的交流调谐滤波器的改进方案,并采用了PSCAD/EMTDC进行了模拟仿真,证明了这种滤波器改进方案是切实可行的。

Research on Simulation of Reactance-adjustable AC Tuned Filter
Abstract:Recent years, power gird is being seriously polluted by harmonic with the mass use of non-linear load such as electronic power devices. Passive AC tunable filter is the most common harmonic suppression equipment in solving the harmonic pollution problems. However, this tunable filter has some disadvantages, such as detuning, over-current, reactive power optimization. This paper proposes an improved AC tunable filter based on adjustable reactance and carries out simulations under PSCAD/EMTDC. Simulation results show that this improved scheme of reactance-adjustable AC tuned filter is practicable.
Keywords: reactance adjustable tunable filter PSCAD/EMTDC
