abstract={This report deals with an electrical system for variable-speed wind power
plants. It consists of a synchronous generator, a diode rectifier and a
thyristor inverter. The aim is to discuss the system design and control, to
model the losses and to compare the average efficiency of this variable-speed
system with the average efficiency of a constant-speed and a two-speed
system. Only the steady state operation of the system is discussed. Losses in
the system are modelled, and the loss model is verified for a 50 kVA
generator. The proposed simple loss model is found to be accurate enough to
be used for the torque control of a wind turbine generator system. The most
efficient generator rating is discussed, and it is shown how the voltage control
of the generator can be used to maximize the generator and converter
efficiency. The average efficiency of the system is calculated. It depends on
the median wind speed of the turbine site. It is found that a variable-speed
system, consisting of a generator and a converter, can have an average
efficiency almost as high as a constant-speed or a two-speed system. Three
different control strategies and their effect on the system efficiency are
investigated.},
