Abstract

The self-excited wound-rotor induction generator excited with condenser can be used for the small capacity wind power generator as independent source.
Under constant exciting condenser capacity, the secondary circuit power of the induction generator is returned to its primary through a converter, an inverter and a transformer, and also its power is controlled at the inverter so that the generator voltage is maintained always a constant value in spite of the change of generator speed and its load. Under above mentioned conditions, generator basic characteristics are analyzed.
The fundamental waves of both the main circuit and the feed back circuit are found. Using these results the equations of various portions of the generator are established, and solving simultaneous equations performance characteristics of the generator are analyzed and compared with experimental results.
