Abstract:
An overview is presented of the international standard committees, ECdirectives and prescriptions, and of the EC, Dutch and Czech standards
concerning the electrical interface from wind turbine to grid. A number of
electrical systems is listed together with some relative price indications.
From some of the systems the physical laws of the generators used therein are
given. Also listed are the most common and practical power electronic
converter-generator combinations, together with the machine efficiencies and
semiconductor device ratings in some sets. Furthermore, the different design
methods are summarised for the (electrically excited and permanent magnet)
synchronous machine, the induction machine and the switched reluctance
machine. Finally, the 'WindGen' design programme for the design of generators
for wind power stations is discussed as well as a methodology to compare
different (synchronous machine types and the induction machine) generator
concepts of different power and speed. 126 figs., 47 tabs., 4 appendices, 39
