& Sciences Publication Pvt. Ltd. Performance, Analysis and Simulation of Wind Energy Conversion System Connected With Grid

Abstract- This paper deals with permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) integrated with grid with two back to back connected converters with a common DC link. The machine side converter is used to extract maximum power from the wind. In this paper a study of WECS is done by using a constant speed wind turbine and 2 mass drive train in Matlab. Moreover, by maintaining the dc link voltage at its reference value, the output ac voltage of the inverter can be kept constant irrespective of variations in the wind speed and load. An effective control technique for the inverter, based on the pulse width modulation (PWM) has been developed to make the line voltages at the point of common coupling
