PROBLEM TO BE SOLVED: To provide a gas turbine power generating equipment, capable of ensuring power supply for critical loads by maintaining the operation thereof, when an voltage is instantaneously lowered or an excessively large torque occurs in a generator for a short time due to power failure, and reducing the size thereof by shortening the length for installation. SOLUTION: A planetary gear speed reducer 10 is installed between a gas turbine 1 and the generator 5. The planetary gear speed reducer comprises an elastic deforming means 12 on the output side thereof. In the elastic deforming means, strain energy within the limit of the elasticity thereof is set larger than the variable torque energy of the generator, when the voltage is instantaneously lowered. The elastic deforming means 12 is formed of an elastic member for elastically connecting the output shaft 10a of the planetary gear speed reducer to the outer ring 10b thereof. |
