- Abstract
The active frequency shift islanding detection method with traditional inverter structure has great influence on power quality. Due to this problem, the structure of the traditional inverter and the principle of the island effect are explained. The principle of Z source inverter and the principle of hybrid island detection method are analyzed successively. Above all, a hybrid island detection method based on Z source inverter is proposed. The inverter structure adopts a modified Z-source inverter, and the blind zone discriminant model is used to automatically select the detection method and to determine the island occurrence. The simulation results show that the hybrid method proposed in this paper can detect the occurrence of islanding effect under various load conditions and reduce the impact on power quality.
