Abstract

The generation of electrical power in isolated remote areas depends on the utilization of renewable energy resources such as wind, solar and geothermal energies. Self-excited induction generators (SEIG) have been widely used in electric power plants utilizing wind energy. This paper introduces a digital simulation and a control technique of a stand-alone SEIG scheme driven by a wind turbine as an external mechanical prime mover. The SEIG scheme will be simulated under the PSCAD/EMTDC environment. The proposed control scheme consists of two parts. The first pan controls the turbine blades pitch angle (β) to compensate the variations in the rotor speed due to the variations in the wind velocity. The second part regulates the load voltage waveform in magnitude and frequency within the acceptable limits using a PWM inverter. Two PI controllers will be used to provide the control signal for each of the two parts, Results are presented in the paper to demonstrate the effectiveness of the proposed control scheme.
