Abstract:
Purpose.Renewable energy sources coupled with a rational use of energy can reduce the fossil fuel consumption and, thus, reduce environmental and socioeconomic effects regardless of the energy demand. This study proposes a control of PMW converter scheme for a doubly-fed induction generator at variable speed wind power generation.
Methodology. The research considers three main feeding techniques of DC Bus: 1) ideal continuous (DC) voltage; 2) the use of an uncontrolled rectifier; 3) the use of a PMW controlled rectifier.
Findings. The results show that switching a three-phase inverter in a wind turbine conversion chain is the key to improving the power quality and ensuring maximum participation of the chain in the service-system.
Originality. Surveillance and control of the effect of the DC bus in the objective ensure the active and reactive decoupled power control so that wind turbines are controlled to provide constant active and reactive power during certain periods for contributing to the service system taking into consideration the particular wind speed in Algeria.
Practical value. With the approach suggested, the controlled PMW converter should have wider applications in a great variety of wind power generation using a doubly-fed induction generator.
