The amount of energy extracted from the wind energy system not only depends on the wind regime but also the control strategy incorporated. This paper presents the concept of extracting maximum power from a wind turbine generating system. An ANN based wind speed estimator is designed which would give the desired wind speed required to deliver maximum power. The proposed control strategy would deliver...
A different topology for brushless doubly-fed induction generators is presented. A power conditioning system is mounted onto two coaxially connected wound rotors. Carbon brushes and slip rings are replaced by the wound rotors and the rotor-mounted power condition system, which bi-directionally exchanges power to the grid with appropriate amplitude and phase difference between the voltages applied...
During recent years the market for small wind turbine generators (SWTG) has been continuously growing. In this context, the supply of components for this product has also been increasing. The main components of SWTG are the rotor, the generator and the wind energy conversion system (WECS), typically formed by a rectifier plus an inverter. The settings of WECS affect the SWTG behaviour, especially...
The recent development of power electronic technology encourages to use variable speed wind turbine (VSWT) driving a doubly fed induction generator (DFIG), wound field synchronous generator (WFSG) or permanent magnet synchronous generator (PMSG) for wind power generation. Among those, stability analysis of DFIG type of VSWT has already been reported in many literatures. On the other hand, stability...
