Abstract
A gas turbine power generation system is configured by a gas turbine, a main power generator which is coupled to a rotor of the gas turbine through a rotation shaft, a rotation rectifier which converts a three-phase AC current into a DC current and transfers the DC current to a field magnet winding wire of the main power generator, an AC exciter which is configured by an armature winding wire, a d-axis field magnet winding wire, and a q-axis field magnet winding wire, and transfers the three-phase AC current generated at the armature winding wire to the rotation rectifier, an excitation device which drives the AC exciter at the time of start-up of the main power generator, and an excitation power supply which supplies a current to the excitation device.
