A power generation system (300) is provided with a main turbine (6) which operates while the system is in operation, and one or more sub-turbines (4A, 4B) which operate or stop according to the situation while the system is in operation, a main speed reducer (50) further comprises an idle gear (53) that lies between a main drive gear (51) and a main driven gear (52) and transmits the rotation of the main drive gear (51) to the main driven gear (52), and the output shaft of a first sub-turbine (4A) included in the one or more sub-turbines (4A, 4B) is connected to the main driven gear (52) via a clutch (66). The first sub-turbine (4A) and the main turbine (6) are disposed axially on the same side with reference to the main speed reducer (50), and the main turbine (6) and a power generator (2) are disposed axially on the opposite sides to each other with reference to the main reducer (50). |
