Modeling and simulation of a wind turbine-generator system

A detailed electrical model of a wind turbine system equipped with a permanent magnet alternator (PMA), diode rectifier, boost dc to dc converter and inverter is presented. The power conversion system topology is explained and the electrical model of each component is presented. Based on this electrical model, a Simulink model of the system is constructed. The simulation was implemented in the power system simulation tools in MatLab SIMULINK. The output curves of the Simulink model (currents, power and voltages) and the actual measurement at the same wind speed taken from the actual operation of the 2.4 kW wind turbine installed at UMass-Lowell are in good agreement. The analysis of the results demonstrates the effectiveness of the constructed Simulink model which can be used to predict the performance of the wind turbine generator system. The steady state performance of the said wind turbine is also presented.
