摘要:
针对输配电系统中的PWM整流变频系统谐波危害问题,文章基于输配电系统主电路拓扑,介绍了PWM整流控制和SPWM调制的基本原理,并基于二重傅里叶变换详细分析了PWM整流系统谐波产生的主要机理及谐波频带的分布,推导出调制比、变压器漏抗对网侧谐波的影响。仿真结果验证了该PWM整流变频系统谐波特性理论分析的正确性。
Abstract:
In order to solve the problem of harmonic harm of PWM rectifier variable frequency system in power transmission and distribution system, it introduced the basic principle of PWM rectifier control and SPWM modulation according to the main circuit topology of the system, analyzed the main generation mechanism of harmonics and the distribution of harmonic frequency spectrum in the PWM rectifier system through the double Fourier transform, and deduced the influence of modulation depth and transformer leakage inductance on grid side harmonics. Simulation results verified the correctness of the harmonic characteristics analysis.
