摘要:为了更合理地设计滤波器,并验证其滤波效果,创建了一种基于实测谐波数据、按无功容量补偿法计算各滤波支路参数,并用Matlab仿真对滤波效果进行验证的新方法。该方法以电流源叠加原理模拟谐波源,并结合滤波器支路的仿真电路,可以准确模拟谐波情况和滤波器的滤波效果,显示滤波前后的电流电压波形。最后,以某实际电力用户为例进行了各种滤波方案的对比设计,提出了无源滤波器实际工程实施时需要注意的重要事项。研究结果表明,该方法具有很强的通用性,简单方便,较好地解决了滤波器设计效果的模拟问题。

Abstract: In order to design a more reasonable filter and testify its effects, a new strategy was presented, the filter branches and their parameters were designed according to the actual harmonic data and by means of the reactive power compensation capacity , the filtering effects were evaluated by a developed Matlab simulation circuit . Combining with the harmonic current sources simulation based on the superposition principle and the filter branches, the conditions of harmonics and the filtering effects can be simulated exactly, and the current and voltage waveforms can be displayed. Several solutions of the filter were designed and compared for a real power consumer. In the end, some key engineering experiences of the passive filter were presented. The results show that the design strategy is universal and simple ,and has given a good solution for filtering effects simulation.
Key words: harmonics; passive filter; Matlab simulation
