Capacitor for generator excitation
WebExcitation of Induction Generator: As a generator, induction machine has severe limitations. Because it lacks a separate dc field current, an induction generator needs ac excitation current. There are two ways to provide this required AC excitation as 1) Grid Excitation 2) Self Excitation – capacitor excitation Webgenerator was developed [8, 9]. The synchronous generator self-excitation systems described in [10-13] have a lot of disadvantages as, for example, complexity in production and low level of residual magnetism. The capacitor activated self-excitation system was developed to allow self-excitation without generator rebuilding, but the testing of ...
