MODELLING AND CONTROL OF STANDALONE WIND ENERGY CONVERSION SYSTEM

In this paper, a Wind Energy Conversion System (WECS) is discussed. The power conversion system consists of a Permanent Magnet Synchronous Generator (PMSG), a rectifier and an inverter connected to the grid. An intermediate DC bus exists between the rectifier and inverter. This conversion system use the PMSG because of its high performances, small size and its low weight compared to induction generators. The generator torque is controlled according to the generator speed and thus the power from a wind turbine settles down on the maximum power point by the MPPT control method. Modeling and Simulation of all the components has been done in MATLAB/Simulink.
