Hybrid PV-wind generation shows higher availability as compared to PV or wind alone. For rural electrifications, researches are focused on hybrid power system which provides sustainable power. The variable voltage and frequency of the self excited induction generator (SEIG) is rectified through Vienna rectifier (three switches) to the required D.C voltage level and fed to common D.C bus. The variable output voltage of PV module is controlled by DC/DC converter using proposed fuzzy logic controller and fed to common D.C bus. The DC bus collects the total power from the wind and photovoltaic system and used to charge the battery as well as to supply the A.C loads through inverter. A dynamic mathematical model and MATLAB simulations for the entire scheme is presented. Results from the simulations and experimental tests bring out the suitability of the proposed hybrid scheme in remote areas.

考虑到不平衡电网条件下，传统锁相环的局限性，这里比较了几种基于正负序分离的锁相环着重基于陷波器的提取方式(Taking into account the unbalanced grid conditions, the limitations of the traditional PLL, where positive and negative sequence based on comparison of several separate PLL trap of focusing on ways to extract)
