Özet:

 

Long-term shaft-induced voltage could harm synchronous   generators, specifically their bearings and insulators. This paper   investigates the reduction of shaft-induced voltage using both a passive   filter and an active voltage regulator. An RLC circuit is used as a passive   filter, and a DC-DC buck converter is used as an active voltage regulator.   As a result, they remove high-frequency spikes, leading to the reduction of   shaft-induced voltage. Buck converters show minimum-phase behavior and can   pose as stable-casual converters. A 5 kW synchronous generator was   considered for the laboratory setup in which a static excitation system   using a 6-pulse thyristor rectifier supplies the rotor winding. Active and   passive filters were placed between the rectifier and the excitation winding   of the synchronous generator. Both simulations and experiments show that the   suggested filters are capable of efficiently removing the parasitic   capacitance, significantly mitigating shaft-induced voltage. However, the   active voltage regulator performs better than the passive filter in reducing   shaft-induced voltage. This reduction can increase the lifespan of bearings   in a generator.
