Abstract
A static exciter system () for the field winding () of a generator () which is connected to a grid system via a busbar () includes a first device () for production of a DC voltage, which is connected to the field winding () and together with the field winding () form an exciter circuit, as well as a second device (, C, . . . , C) for emission of electrical energy, which second device (, C, . . . , C) briefly feeds additional energy into the exciter circuit when required. An exciter system such as this results in the capability to briefly increase the excitation in a simple, functionally reliable and space-saving manner, by inserting a forward-biased diode () into the exciter circuit, and by the capability to connect the second device () to the diode (), in the reverse-bias direction, in order to feed the energy into the exciter circuit.
