Patent CA-2304356-A1 (CA)
Title: Excitation controller and excitation control method for stabilizing voltage in electric power system
Inventor: SHIMOMURA MASARU
IPC: H02P9/14
Filed: 2000-04-06
Abstract: An excitation controller sets an output terminal reference voltage of a synchronous machine from a reactive current output from the synchronous machine and a high side reference voltage of a transformer, and controls the field current to be supplied to the field winding of the synchronous machine in response to the deviation between the reference voltage and the output terminal voltage.      This makes it possible to solve a problem of a conventional excitation controller in that although it can maintain the transmission voltage on the transmission bus at a fixed value, an expensive PD is needed for detecting the transmission voltage on the transmission bus, which increases the manufacturing cost of the excitation controller.
