An Isolated Wind?Hydro Hybrid System with Two Back-To- Back Power Converters & Battery

P. Mahamood Khan , G. Avinash Kumar

This paper presents a three phase four wire local loads connected two squirrel cage induction generators (S.C.I.G) , one driven by a variable wind turbine and another driven by a constant power hydro turbine. The proposed system has a battery at the middle of the two back-to-back connected PWM controlled IGBT based voltage source converters(VSCs).The two VSCs are used to achieve maximum power tracking (M.P.T) at the machine side (Wind power generation side) and to regulate the magnitude and the frequency of the load voltage at load side(Hydro power generation).
