Abstract: An abnormality detection system for a combustor for a gas turbine, includes: a sensor for detecting whether an ignition plug is located at an insertion position in a combustion tube of the combustor for the gas turbine, the ignition plug being disposed movably between the insertion position and a retracted position retracted from the combustion tube; and a diagnostic unit configured to diagnose an abnormality in an ignition device including the ignition plug, based on a detection result by the sensor.

Abstract: A power transmission apparatus includes an input shaft inputting power, an output shaft outputting power, an energy storage portion arranged between the input shaft and the output shaft and configured to store energy sent from the input shaft, and a power transmission portion allowing a difference between a rotation speed of the input shaft and a rotation speed of the output shaft, the power transmission portion including a portion serving as an elastic body that is configured to store torsional deformation, the energy storage portion converting a kinetic energy into a different energy from the kinetic energy and storing the converted energy to achieve power transmission between the input shaft and the output shaft including different rotation speeds from each other.

Abstract: During an inertial energy storage operation, electric power conversion at an inverter is controlled such that a direct current electric power from an electric power storage device is converted into an alternating current by the inverter so as to be supplied to stator windings, such that torque in the direction of engine rotation is applied to an output side rotor from a stator to rotatively drive the output side rotor in a state where power transmission from the output side rotor to a drive axle is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter is controlled to permit application of the alternating current to rotor windings, such that a torque in the direction of engine rotation is applied to an input side rotor from the output side rotor, thereby rotatively driving an input side rotor to crank the engine.
