MODELING AND SIMULATION OF WIND TURBINE COUPLED WITH A PERMANENT MAGNET SYNCHRONOUS GENERATOR UNDER GRID CONNECTED SYSTEM

The objective of this paper is to model and simulate the grid connected wind mill using MATLAB/SIMULINK. Wind energy is a renewable energy and its running cost negligible as wind is freely available. The non -renewable energy are being exhausted and therefore there is a need to switch to renewable sources of energy. For utilizing wind energy, wind turbines are used and different parameters like, shape and size of the blades, wind speed, generator characteristics etc. are considered in calculating the efficiency of the turbine. This paper deals with the performance study of the output from the permanent magnet synchronous generator PMSG coupled with the wind turbine. In this case performance test is conducted with two variable speeds and the reactive power, active power, voltage and current waveforms of the inverter is plotted using SIMULINK.
