Wpływ kompensacji indukcyjności uzwojenia na napięcie wyjściowe wolnoobrotowej prądnicy do elektrowni wiatrowej

The paper presents the construction of multipole low speed generator destined to wind power plant of vertical axis. Due to low rotational speed - 125 rev/min and necessity of generation of voltage of 230V,winding of this generator consists of many coils causing a significant increase of its inductance. At the load of generator, a high voltage drop in the winding reactance takes place what in turn causes the significant reduction of output voltage generated by the generator. The voltage drop in the reactance can be compensated by parallel connection of capacitors, however it cause an increase of current being drawn from the generator and heating of winding. The paper presents also the influence of the capacitance on the output voltage of generator.
