单相混合型电力滤波器的研究

Study on single-phase hybrid power filter

针对电气化铁道谐波特性以及无功综合治理要求,设计了一种新型的可以很好补偿由交-直流型电力机车供电系统所产生的无功功率以及谐波电流的单相混合型滤波器(HAPF),由有源电力滤波器(APF)和无源滤波器(PF)共同组成。通过对此混合滤波器谐波的有关补偿原理研究,制定了一个通过反馈来实现的控制策略。并且基于MATLAB的SIMULINK环境,进行了仿真模型构建,其结果显示此策略有效,HAPF能够很好地改进电气化铁道系统的无功以及谐波。

In view of the requirements and characteristics of the comprehensive treatment of harmonic and reactive power in electrified railway, a novel single-phase hybrid power filter composed of active power filter （APF） and passive filter （PF） was proposed to compensate the harmonic current and the reactive power caused by AC-DC type of electric locomotive in power system. By analyzing the compensation principle, this paper presented a new feed- back control strategy. The simulated model was established by using of simulink in matlab, study results illustrated that the HAPF has a good performance in harmonic suppression and reactive power compensation.
