Abstract: A method for positioning a rotor of a gas turbine automatically is provided that includes gathering data with a control unit, and processing this data to bring the rotor to a desired position which is set according a Human Machine Interface (HMI). The indication of the lay of the rotor to the control unit is done by a key phasor, which includes a sensor which gets a digital pulse for each revolution of a phasor cam wheel. This digital pulse is used to give the information of the lay of the rotor to the control unit.

Abstract: A device for positioning the rotor of a gas turbine by linearly actuating a piston rod that actuates on its end a ratched wheel that moves the rotor of the gas turbine. The device includes an eccentric wheel and a synchronous motor. The piston rod is moved through the eccentric wheel, which is connected to the synchronous motor. The device also includes an incremental counter controlling the angular position of the synchronous motor. The device can permit accurate positioning of the rotor for boroscopic inspection.

Abstract: The present invention relates to a gas turbine power generation system, that includes a hydrogen-cooled generator having hydrogen as coolant, a plant hydrogen storage, generator auxiliaries and an emergency power supply system. The power generation system includes a fuel cell using hydrogen as fuel. The fuel cell is supplied via a line with hydrogen fuel from the hydrogen filling of the hydrogen-cooled generator in case of failure or disruption of the power supply from the gas turbine power generation system. In a preferred embodiment the fuel cell is supplied with additional hydrogen via a line from the plant hydrogen storage and/or with additional hydrogen via a line from generator auxiliaries in case of failure or disruption of the power supply from the gas turbine power generation system.
