摘要
为了满足大功率场合对电网谐波治理的需求,建立了基于预测电流控制和空间矢量调制的二极管箝位型三电平并联有源电力滤波(Shunt APF)实验装置,对基于旋转坐标变换的谐波提取方法和预测电流控制方法进行了阐述。提出了通过增加饱和环节来减小插值运算产生的补偿电流超调问题。介绍了三电平SVPWM在DSP中的实现方法。算法仿真和实验结果说明该装置具有较好的谐波补偿效果,应用前景良好。
An equipment of diode-clamped three-level shunt active power filter（APF） based on predictive current control and space vector modulation is built to meet the needs of harmonic elimination.Harmonic extraction based on rotating coordinate transformation and predictive current control methods are discussed.Saturation loop is adopted to minimize the compensation current error caused by interpolation algorithm.Realization of three-level space vector pulse width modulation in DSP is introduced.The computer simulation and experimental results show the good compensation effect and application prospect.
