Adaptive Gain Scheduling Control of Doubly Fed Induction Generator Based Wind Turbines to Improve Fault Ride Through Performance

Ahmad Khajeh; Zahra Shabani

Volume 1, Issue 1 , June 2018, , Pages 61-70


  The Doubly-Fed Induction Generators (DFIG) based Wind Turbines (WT) are widely used in WTs connected to power systems. Traditionally the back-to-back converters are used in order to control the DFIG. In this paper, an Indirect Matrix Converter (IMC) is utilized. Compared with back-to-back converters, ...  Read More
