An analysis of transient characteristics of interconnected DFIG with hydro governor synchronous generator

Abstract

With increasing the penetration of wind power into electrical grids, DFIG wind turbines are largely developed due to the variable speed feature and hence influencing system dynamics. A detailed mathematical model of DFIG with a closed-loop vector control system is developed. Based on this, objective functions of the transient conditions are implemented and to optimize the controller parameters of both the rotor and grid-side converters. This paper deals the behaviour of interconnected DFIG with hydro-governor synchronous generator with the transient and post-transient operating conditions. During these conditions, the variations of real and reactive power flows of synchronous and asynchronous generators are analysed by PSCAD/EMTDC software.
