Research on Current Control Strategy of APF Based on Indeterminate Frequency Hysteresis

Full Text(PDF, 1805KB)

Author: Hui Qi, Cong Zhao

Abstract: Harmonics in the grid is widespread. Active power filter (APF) is currently the primary means to control the harmonic pollution in the grid. In order to improve the current tracking performance of active power filter, a current control strategy of space vector pulse width modulation (SVPWM) based on indeterminate frequency hysteresis has been proposed in this paper with the combination of hysteresis control and the space-vector modulation. In this way, the optimal voltage space vector could be determined and the current high performance control was obtained as well. In this study, the Simulink software was used to simulate the strategy referred above. The results of simulation showed that as compared with the control strategy of space voltage vector based on the command voltage vector, the strategy proposed in this paper has some advantages in improving the control effect and reducing the harmonic pollution.
