Beschreibung:
<jats:p> This paper considers constant-speed electricity generation using induction generators. Taking typical wind-farm site data, a case study allows performance evaluation of the previously proposed delta-star induction generator feeding power to the grid. By making an annual estimation of energy fed to the grid and reactive power drawn from the grid, advantages of this multi-stage generator are shown. A method for studying the effect of variation in wind speed pattern, on the annual reactive power drawn from the grid is indicated. A performance comparison with some other wind-driven constant-speed induction generator systems is also made. </jats:p>
