Abstract
There is provided a planetary reduction gearbetween a gas turbineand a generatorThe planetary reduction gear includes elastic deformation uniton 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 unitincludes an elastic member which elastically connects an output shaftof the planetary reduction gear to an outer ringThereby, 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.
