Comparative study among different wind turbines used for wind energy system

Abstract

The global electrical energy consumption is steadily increasing and the installed classical high power stationeries cannot fulfill the demand on the other hand, continuous decrement of fossil fuels make incentives to invest alternative energy sources like wind power. Generally Squirrel Cage induction generator (SCIG), Doubly Fed Induction Generator (DFIG) and Permanent Magnet Synchronous generator (PMSG) are used in the wind power generating systems. Individual power coefficient is calculated for different tip speed ratio at fixed rotor speed for the above mentioned generators. A comparative efficiency performance has also been carried out in this paper and the most efficient turbine generator is found.
