dc.description.abstractDirect grid coupling of permanent magnet synchronous generators (PMSG) for wind energy conversion systems provides certain advantages with the penalties of maximum power point tracking (MPPT) and reactive power control. This article proposes a novel PMSG design philosophy such that optimizing PMSG design at the initial stage would compensate for the drawbacks arising from the lack of an MPPT algorithm. Also, the ability to maintain a high PF across a wide range of operating power levels is investigated by considering reactive power in the design process. In this article, optimization of slot/pole combination is described for direct grid coupled PMSGs to extract as much energy as possible according to wind data. A new benchmark, adequacy factor, is presented to determine the slot/pole combination. Variation of the reactive power is theoretically analyzed. A relationship is established between induced electromotive force, synchronous inductance values of machines, and the PF. Fixed and variable speed operations of PMSGs are compared in terms of annual energy yield. Finally, theoretical analyses are validated through laboratory testing of prototype generators.
