An excitation controller controls excitation of a synchronous machine, which is connected to a power transmission system through a transformer, so that a high-side voltage of the transformer is maintained at a target voltage with high accuracy. An output terminal target voltage of the synchronous machine is set to precisely compensate for a voltage drop in the transformer, corresponding to the transformer phase angle variation. To achieve this result, the excitation controller detects an output terminal voltage and an output current of the synchronous machine and calculates active and reactive currents of the output current, sets the output terminal target voltage of the synchronous machine from the active and reactive currents, the high-side voltage of the transformer, and the reactance of the transformer, and controls excitation of the synchronous machine to compensate for the voltage drop in the transformer corresponding to phase angle variation of the transformer.

Excitation controller and excitation control method for stabilizing voltage in electric power system

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 supplied to the field winding of the synchronous machine in response to the deviation between the reference voltage and the output terminal voltage. Although a conventional excitation controller can maintain the transmission voltage on the transmission bus at a fixed value, an expensive potential detector is needed for detecting the transmission voltage on the transmission bus, which increases the manufacturing cost of the excitation controller.
