Abstract

PURPOSE:To remove the variation of the vibration of a shaft at the time of starting by a method wherein a rotor is turned at the rated number of revolution and preheated, the number of revolution is decreased, and a wedge is extended during the time when centrifugal force not apply. CONSTITUTION:When starting the turbine generator, the speed of revolution of the generator is increased up to the rated number of revolution nc, and the rated number of revolution is maintained for a fixed time. The excess of a gas temperature B in the generator over a limit temperature TL set previously is identified at that time. And the speed of the generator is decreased up to the speed of turning at once, and increased again to reach the rated number of revolution nc, and the generator is brought to a normal operation. Accordingly, the starting method for the turbine generator hardly causing the vibration of the shaft vibration at the time of starting can be obtained.
