摘要
该文首先介绍了电力系统中三种常用无源滤波器的工作原理,然后利用电磁暂态仿真软件PSCAD/EMTDC搭建了这三种无源滤波器模型并分别进行了仿真,最后对仿真结果进行了对比分析,得出这三种无源滤波器在滤波性能和特征谐波阻抗方面的优缺点。此研究对钢铁公司变压器二次侧的谐波抑制和无功补偿的参数设计具有一定参考价值。
Firstly,this paper mainly introduced the principle of three kinds of passive filters commonly used in the power system.Then based on the simulation of electromagnetic transient simulation software PSCAD/EMTDC we built three filter models and the simulation results were compared in order to get the ad-vantages and disadvantages of the filter characteristics and the characteristic harmonic impedance of the three kinds of passive filters.This research is of certain reference value to design of parameters of reactive power compensation and harmonic control of the secondary side of the steel company transformer.
