摘要
为提高滤波性能,改善滤波器输出电流波形,设计了一种新型有源电力滤波器。通过采用基于傅立叶变换的谐波电流检测算法快速准确地检测三相谐波电流,利用LCL滤波器有效滤除高频谐波及开关纹波。在Matlab/Simulink仿真平台中构建了系统仿真模型,仿真结果表明,该系统具有良好的谐波跟踪和补偿性能,验证了该方案的可行性。
In order to improve the filtering performance and the eurrent waveform outputted,a novel active power filter is designed. A detecting algorithm of harmonic current based on fourier transforms is adopted to detect three-phase harmonic currents quickly and accurately, and a LCL filter is utilized to filter the high-frequency harmonic and switching ripple effectively. The simulation model of this system based on Matlab/Simulink is constructed. Simulation results show that the performance in harmonic tracking and compensating of the system is good which validated the feasibility of the scheme.
