Patent DE-19523302-A1 (DE)
Title: Electrical generator excitation control method
Inventor: HOPFNER FRANK DIPL ING
IPC: H02P9/10
Filed: 1995-06-27
Abstract: The excitation control method uses a control characteristic for excitation of the generator in dependence on the actual generator loading, for rapid response to load variations of the electric motor, supplied by the generator via a current regulator.  Pref. the actual generator loading is determined from the current loading of the generator, measured directly at the generator, or calculated from the control characteristics of the current regulator and the sum load DC, with corresponding regulation of the generator excitation current between min. and max. rev values.
