摘要：To enhance furtherly the current of compensation performance, a novel strategy of gray prediction and voltage vector controlling APF is proposed. This method produce leading current instruction based on gray predicting of nonlinear load current, moreover, this instruction implementated the optimal voltage vector controlling of double hysteresis-current control for APF. As far as voltage vector controlling is concerned, including the concept of target region, weak controlling region and strong controlling region, clearly and compactly describing voltage vector controlling basing on current error; As for gray prediction of load current and formation of APF leading current instruction, determining gray forecast parameters for APF experimental system. The contrast and analysis of simulation of pure dynamic resistance and unbalanced load show that gray forecast and voltage vector controlling can improve furtherly compensation precision and decrease THD of current in power source side, besides the advantage of maintaining conventional voltage vector controlling APF.
