摘要
三相电压源型PWM整流器被广泛地应用于新能源发电、电气传动、高压直流输电、有源电力滤波、静止无功补偿等领域。在大功率场合,三相电压源型PWM整流器常使用LCL滤波器来滤除PWM整流器开关频率处的高频谐波。针对LCL滤波器传统设计方法的不足,提出了应用遗传算法来设计LCL滤波器的方法。仿真结果表明,因此遗传算法是一种更为有效更加简单的设计方法,实验结果也证实了此方法的正确性。
Three-Phase PWM Voltage Source Rectifier is widely used in the new energy power generation, electric drive, HVDC transmission, active power filter, static var compensation and other fields. Three-Phase PWM Voltage Source Rectifier uses an LCL filter to reduce the harmonic distortion at switch frequency situation. According to the deficiency of the LCL filter traditional design method, a new method with genetic algorithm （GA） is presented in this paper. The simulation result proved that genetic algorithm （GA） is more effective and simple than traditional methods. And the experimental results also confirmed the correctness of this approach.
