Performance Analysis of Grid Coupled Doubly Fed Induction Generator in a Wind Power System
Authors: ,
Abstract: Wind power is one of the alternative renewable energy sources free from Co2 emission to the environment and best complement for other sources to meet the energy demand of one’s country. The Doubly Fed Induction Generator (DFIG) is the most commonly used types of machines in wind power system due to its variable speed of operation, reduced converter size, better power quality, and the ability of independent power control. This paper analyses its performance under various operating regions by modeling the machine and designing a Proportional-Integral (PI) controller for tuning the parameters at reference points. The Pulse Width Modulation (PWM) strategy is used for controlling the converters. The results are get compared with factory test reports of the machine, numerical analysis, and simulations. They are found to match each other and hence the study can be an important input to a further insight of induction generators in wind power system. Matlab/Simulink software is used for modeling and simulations. The stability of the machine is also analyzed and found to be stable.
