Among the existing renewable sources, wind energy is reaching production rates that are becoming important on the worldwide energy scene. Since the control of these wind generators is a very technical discipline, practical teaching methodologies are of special relevance. Paradoxically, in the past, the training of engineers specializing in this area has lacked the practical component represented by...
Dual stator-winding induction generator scheme based on excitation converter has been proposed for new-style integrating power system as tank. The dynamic model of dual stator-winding induction generator system with a diode bridge rectifier in the stationary reference frame is setup. The simulations of dynamic performances based on stator voltage oriented of control winding with variable speed under...
This paper addresses the representation of a wind power plant, based on wound rotor asynchronous generators, with a centralized voltage controller, by an equivalent transfer function, valid for small signal voltage control studies. This representation allows to investigate the influence of the centralized plant control gain and short circuit ratio on the system stability, for instance, by analyzing...
This paper presents control of doubly fed induction generator for variable speed wind power generation. The control scheme uses stator flux-oriented control for the rotor side converter and grid voltage vector control for the grid side converter. A complete simulation model is developed for the control of the active and reactive powers of the doubly fed generator under variable speed operation. Several...
The doubly-fed induction generator (DFIG) is a 'special' variable speed induction machine widely used in modern large wind turbines. It is a standard, wound rotor induction machine with its stator windings directly connected to the grid and its rotor windings connected to the grid through a back-to- back PWM converter. The DFIG power generation consists of power delivered from two paths, one from...
