Modeling and performance analysis of a direct driven PMSG for variable speed wind energy conversion system
Abstract
The main purpose of this work is to develop a wind energy conversion system model to analyze the behavior of a permanent magnet synchronous generator (PMSG) for variable speed application. The PMSG modeling in this study is done using the approach of state space representation of the d-q models theory for AC machines. In this work, the MATLAB/Simulink programming and graphical environment has been used to develop the wind energy conversion system modeling and simulation. This modeling includes the wind turbine and the PMSG models. Using this simulation tool, the dynamic analysis and performance evaluation has been achieved for a 1KW PMSG. All the system components and system response have been observed closely under different wind speeds. This research analyzes the model of a variable speed wind turbine equipped with 1 KW PMSG. The wind energy conversion system is emulated with a complete test-bed to validate the theoretical and simulation results. The test-bed includes the PMSG, a Three-phase induction motor, a rectifier, sensors measuring the generators line-to-line voltages, two phase currents, the rectifier's output DC current and the rotational speed of the shaft. A variable frequency drive (VFD) is used to control the motor for providing variable speeds to the PMSG for analyzing the behavior. A charge controller is used for a battery charging application of the system.
