| Abstract |
In the last two decades renewable energy systems have become of major interest all over the world.
Besides the well established generation of electrical energy by hydropower, wind energy systems have
proved to be a technical and economical alternative to the conventional thermal power stations. Different
concepts of wind turbine systems are on the market, which differ not only in total power and
mechanical design, but also in the way the mechanical energy of the rotating turbine is converted to
electricity. The increasing power of the wind converters and their integration into wind parks demands
for a higher control level, for an efficient control of the speed as well as the active and reactive power
of the generator. In the present paper the asynchronous slipring generator with inverter control in the
rotor circuit is presented in detail. The major characteristics of the system are discussed. |
