摘要
谐波治理非常重要的手段之一是采用各种形式的电力滤波器滤除相应谐波,滤波器参数设计不合理就会与电网发生谐振,产生谐波放大的情况。针对以往设计过程中存在参数调整困难、无法及时得到滤波效果的直观显示等问题,设计了一种基于MAT-LAB GUI的电力滤波器设计与软件仿真平台,友好的人机界面下能实时便捷输入或修改系统参数,通过软件计算与分析,可以立刻得到系统的阻抗曲线、滤波前后谐波电压和电流的THD值,通过适当调整,可以获取最佳设计参数,有效克服以往设计过程中容易发生的谐波电流放大问题。多项具体工程应用中良好的仿真效果证明了该仿真平台的有效性和可靠性。
One of basic measures for harmonic elimination is to adopt the various forms of power filter.if parameters are designed unrea-sonable,power filter and grid would occur harmonic oscillation,resulting in the harmonic amplification.In view of parameters adjustment difficulties and the problem unable to get a visual display in actual design process and etc.A designing software and simulation platform for power filter in MATLAB GUI environment is proposed in paper.With Friendly man-machine interface it is convenient and real-time to enter or modify system parameters,calculation and analysis can immediately get the system resistance curve and harmonic voltage and cur-rent THD value before and after filtering,by adjusting,you can obtain the optimal design parameters and be effective to overcome the problem of harmonic current amplification in the past design process.The actual effectiveness and reliability of software is verified in multi-ple practical Engineering applications.
