。The present invention provides a turbine generator with a large inertial force.While a turtle-like turning device inevitably requires a large capacity, the present invention uses a jack that supplies high-pressure oil to each shaft of the turbine generator during turning operation. Since the turning operation is performed, if this effect is good, compared to the driving force on the turning device side,
The various losses that occur in the turbine generator shaft are small, and as a result, when performing turning operation, the driving force on the turning device @ side becomes excessive, and conversely, the turbine generator shaft side overspeeds, making it impossible to perform stable turning operation. In this system, excessive driving force on the turning device side is absorbed by a brake device provided on the turbine engine shaft.
