The modelling and control of a wide-range variable speed wind turbine based on a synchronous generator are presented. Two different methods to control the operation of the synchronous generator are investigated, i.e. load angle control and instantaneous vector control. The dynamic performance characteristics of these control strategies are evaluated and compared using three model representations of the generator: a non-reduced order model including both stator and rotor transients, a reduced order model with stator transients neglected, and a steady-state model that neglects generator electrical dynamics. Assessment on the performance of grid-side controller is shown during network fault and frequency variation. A simplified wind turbine model representation is also developed and proposed for large-scale power system studies. Simulation results in Matlab/Simulink are presented and discussed.
