摘要
在检测有源电力滤波器谐波电流、指令电流计算和基于PWM逆变电源的补偿电流输出过程中产生的有源电力滤波器延时对APF的补偿特性造成不利影响。为了保证有源电力滤波器具有良好的动态补偿性能,针对单相并联有源电力滤波器提出了基于ARMA(p,q)和LMS自适应滤波器的延时解决方案。通过MATLAB进行仿真验证,结果表明所提出的解决方案具有良好的补偿效果。
The delay of the active power filter which occurs in detecting the harmonic current and in calculating the control current and in the process of the output of the compensation current of the inverter based on PWM exerts adverse impacts on the compensation of the APF.To ensure the dynamic compensa-tion performance of the APF,this paper presents a delay scheme based on ARMA(p,q) and LMS adaptive filter against Single-Phase Shunt Active Power Filter(SSAPF).Verification by MATLAB simulation shows that the delay...
