This paper describes the control of squirrel cage induction generator (SCIG) and its responses to grid voltage unbalance. The paper presents the vector control of SCIG. On the SCIG side converter, the control strategy enables the independent control of flux and electromagnetic torque. On the grid side converter, the control strategy is implemented to… (More)

Wind farms WF connected to the power network are frequently subjected to grid faults, a large rotor current rising proportion happens during grid voltage sags. These faults may cause damages to rotor windings, converters, DC Link capacitor or induce drive train mechanical stress due to torque fluctuations. This paper develops a crowbar and chopper… (More)

In this paper, nonlinear control of permanent magnet synchronous generators (PMSG) for wind energy conversion system (WECS) is investigated in order to maximize the generated power from wind turbine. The control strategy combines the technique of maximum power point tracking (MPPT) method and sliding mode (SM) nonlinear control. A speed and pitch control… (More)

This paper presents a nonlinear control method to track the maximum power point of wind turbine equipped with Squirrel Cage Induction Generator (SCIG). Since the mechanical power of wind turbine is function of its shaft speed at a given wind velocity, the proposed controller provides the desired voltage at the output of Voltage Source Converter (VSC) so as… (More)

This study presents a comparison of linear and nonlinear control to regulate the DC-link voltage and power factor correction of a wind farm equipped with squirrel cage induction generators (SCIGs), connecting to a 22-kV distribution network. Both active and reactive powers are employed in 2 independent control laws. The proposed control strategies are… (More)

A wind farm with variable speed wind turbines usually consists of a large number of wind turbine generators (WTGs) connected and operating simultaneously. The study of a wind farm with permanent magnet synchronous generators (PMSG) is presented. The 10 MW wind farm consists of 5 PMSGs based 2MW generators connected to a common DC-bus. Each PMSG of the wind… (More)

The efficiency of the variable speed wind energy conversion systems (WECS) can be greatly improved using an appropriate control strategy. In this paper, nonlinear control for wind energy conversion system (WECS) based on the permanent magnet synchronous generator (PMSG) is investigated in order to maximize the generated power from wind turbine. The control… (More)

This paper expands a nonlinear fuzzy based control strategy applied to a variable speed Wind Energy Conversion System WECS founded on Doubly Fed Induction Generator DFIG. As power network assists a high wind energy emergence, the studied WECS represents a wind farm WF of 500MW connected to the Grid and dispatched in such a way that it can contribute to grid… (More)
