nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...

This paper describes the modeling and simulation of a wind energy conversion system in Matlab/Simulink environment. The wind energy conversion system consists of a wind turbine, gear box, and induction generator. The dynamic model of a 30 kW induction generator is used for performance testing of the proposed system. Simulink models of the individual components of wind energy conversion are form...

In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...

In this paper the Space Vector Control Scheme is implemented for a Wind Energy System using Three Level Impedance Source Inverter (ZSI). The wind energy system uses a Self Excited Induction generator (SEIG) which is the most emerging application in the field of Wind Energy Conversion System (WECS). The proposed system is modelled with a generator-side Diode Bridge Rectifier and a Stand-Alone si...

More than one hundred countries are using wind energy due to their easy implementation, cheap energy, and high energy efficiency. Implementation of FACTS devices in Wind Energy Conversion Systems (WECS) has been dramatically improved due to cooperative and accurate performance of FACTS devices. However, dealing with wind turbine faults promptly is crucial. Short-term and long-term faults may ha...

This paper proposes a new technique of using Axial Flux Induction Machines (AFIMs) for wind energy conversion systems. The Power Generation by wind is found to be enhanced by using a Twin Rotor Axial Flux Induction Machine (TRAFIM). By using Axial Flux Induction Machines, the gear box ratio can be reduced. The Single air gap and TRAFIM have been mathematically modeled in the environment of MATL...

This paper examines optimum selection of wind turbines between site and wind turbine generators. An analysis methodology is done at the planning and development stages of installation of wind power stations will enable the wind power developer or the power utilities to make a judicious and rapid choice of suitable wind energy conversion system from the available potential sites. The methodology...
