Wind energy conversion system using PMSG

The applications of wind energy develops much more rapidly than the other renewable resources such as solar, geothermal etc. in the 21
^st
century. It becomes the third core energy resource following non conventional fuels as oil and chemical. Electrical energy generated by wind power plants is the fastest developing and most promising renewable energy source. The wind is a clean, free and inexhaustible energy source. The origin of wind is simple. Wind turbines are classified into two types as fixed speed and variable speed wind turbine. A variable speed wind turbine provides more energy than the fixed speed wind turbines, reduce power fluctuations and improve reactive power supply. Basically direct drive PMSG (Permanent Magnet Synchronous Generator) and DFIG (Double Fed Induction Generator) are used in variable speed wind turbine generator. In this paper, the Matlab simulations of a Wind Energy Conversion System with PMSG and variable-speed wind turbine have been discussed.
