摘要
为了得到更好的电能质量环境,比较了LLCL型滤波器、LCCL型滤波器以及混合型滤波器在模拟制动再生馈电系统中的性能,从所观测参数当中的并网三相电压、滤波前后电流及谐波分析(FFT分析),得出最优组合滤波器(LCL滤波器+LLCL型滤波器),可实现制动再生馈电系统的良好谐波抑制效果及获得较低的THD值。
In order to get a better power quality environment, a comparison has been made between the performance of LLCL filters, LCCL filters, and hybrid filters in an analog brake regenerative power feed system. Based on the analysis of three-phase voltage, current before and after filtering and harmonic (FFT) among the observed parameters, the optimal combination filter (LCL filter + LLCL filter) can achieve a good harmonic suppression effect of the brake regenerative feeding system with a lower THD value.
