<p>A static exciter system (20) for the field winding (17) of a generator (16) which is connected to a grid system via a busbar (19) includes a first device (12, 18, 21) for production of a DC voltage, which is connected to the field winding (17) and together with the field winding (17) form an exciter circuit, as well as a second device (23; 29, C1, . . . , C3) for emission of electrical energy, which second device (23; 29, C1, . . . , C3) 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 (22) into the exciter circuit, and by the capability to connect the second device (23) to the diode (22), in the reverse-bias direction, in order to feed the energy into the exciter circuit.</p> |
