Abstract

There is provided a planetary reduction gear 10 between a gas turbine 1 and a generator 5. The planetary reduction gear includes elastic deformation unit 12 on an output side, and for the elastic deformation unit, a strain energy within an elastic limit is set to be larger than a fluctuation torque energy of the generator of a momentary voltage drop time. The elastic deformation unit 12 includes an elastic member which elastically connects an output shaft 10a of the planetary reduction gear to an outer ring 10b. Thereby, when an excessive torque is generated in the generator by a momentary voltage drop, service interruption, and the like for a short time, it is possible to maintain the operation of a power generation facility, and secure a power supply of an important load, and an installation length is shortened and the facility can be downsized.
