摘要:
提出一种基于参考电流动态预测的选择性补偿方法。通过滑窗迭代DFT法提取与参考电流相关的特定次谐波；把动态预测算法植入补偿电流控制环节，预测下一拍的指令电流信号，并引入误差修正器提高预测精度,在此基础上计算逆变器的参考电压矢量；利用空间矢量脉宽调制法获得PWM信号，驱动三相变流器从而输出三相电压，实现选择性补偿。仿真和实验证明了该方法的正确性和可行性。
Abstract:
To improve the compensation performance and efficiency of active power filters, a selective harmonic compensation method was proposed based on the dynamic forecast of reference current. Firstly, the specific harmonics associated with the reference current signal was extracted via sliding window iterative DFT method; then the dynamic forecast algorithm was implanted into the compensation current control link to estimate the reference current signal value at the following sampling period, and an error corrector was introduced to improve the prediction accuracy; and then the reference voltage vector of the inverter was calculated; Finally, the PWM signals to control the output voltage of the three-phase converter were obtained by the space vector pulse width modulation method, realizing the selective harmonic compensation. The simulation and experimental results confirm the correctness and feasibility of the proposed method.
