Abstract:
The study on the title subject involves 5 different design concepts ofvariable speed wind turbines without gear box and with approximately 300-1500
kW nominal shaft power: the electrically excited and the permanent magnet
synchronous machine, the induction machine (radial and axial field) and the
switched reluctance machine. For the selected concepts, design programmes
have been developed, including specific electromagnetic generator models as
well as material and construction costs in order to optimise them for maximum
cost-to-performance ratio's. As a result, the different concepts can be
mutually compared with respect to their ratio of investment costs to yield.
Detailed cost-to-performance calculations have been carried out for 500 kW
direct drive wind turbines. 4 figs., 2 tabs., 8 refs.
