Abstract:

 

The wind turbine generator system is the only generator unit in utility network where mechanical stiffness is lower than electrical stiffness or synchronizing torque coefficient. The inertia constants of the wind turbine and generator system have significant effects on the transient stability of the wind generators and the wind farm. This paper investigates the effects of two-mass drive train parameters in a doubly fed induction generator (DFIG) variable speed wind turbine (VSWT). Extensive simulations were carried out using PSCAD/EMTDC considering two strategies. In the first strategy, different values of the wind turbine and generator inertia parameters were investigated. The wind turbine and generator inertia parameters that give best response during transient in the first strategy were used to determine the best shaft stiffness in the second strategy. The simulation results show that high values of the wind turbine and generator inertia parameters could lead to more oscillations, hence takes longer time for the VSWT to become stable during and after the transient. However, the larger the shaft stiffness parameter of the two-mass drive train system for VSWT, the better the response of the VWST and the wind farm system during transient.
