摘要
针对矿用提升机变流器产生的电流谐波信号,提出了基于改进型希尔伯特-黄(HHT)变换方法的检测分析方法以及改进型有源滤波器的设计方法。通过MATLAB/Simulink软件建立并联APF+SPWM逆变器的混合型有源滤波装置仿真模型,进行谐波动态检测和抑制仿真。结果表明此设计方法可以实时检测提升机变流器产生的的谐波,并可对系统电流进行补偿,对谐波进行有效抑制。
Aiming at the current harmonic signal generated by mine hoist converter, the detection analysis method based on Hilbert - Huang Transform （HHT） and the design method of improved active power fiher were proposed. A simulation model was established using MATLAB/Simulink about shunt APF ＋ SPWM inverter hybrid active filter device for harmonic motion detection and suppression simulation. The results show that, this design method can detect harmonic of hoist converter real -time, compensate the system current, and suppress harmonic.
