- Abstract
- We describe modeling and control methods for a variable speed squirrel-cage asynchronous (induction) generator with power electronic converters. A comprehensive dynamical model of the SCAG wind turbine and its control scheme is presented. The control scheme consists of wind turbine control and power converter control. Wind speed variations, local load variations, and voltage sag are simulated. Through these simulations, the capabilities of the proposed reactive power control design, which can adjust the voltage variations in a point of common coupling (PCC. Bus 4) to preset values when connecting wind power generation systems, are evaluated and discussed. (C) 2011 Elsevier Ltd. All rights reserved.
