Gas turbine power generation system comprising an emergency power supply system

摘要

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.

主权项

1. A gas turbine power generation system, comprising:
a hydrogen-cooled generator; a plant hydrogen storage; generator auxiliaries configured to receive hydrogen from the plant hydrogen storage, process the hydrogen, and feed the hydrogen to the hydrogen-cooled generator for cooling of the generator; and an emergency power supply system that comprises a fuel cell; the fuel cell directly connected to the hydrogen-cooled generator via at least one supply line such that hydrogen is feedable to the fuel cell during purging of hydrogen from the hydrogen-cooled generator that occurs during a failure or disruption in operation of the gas turbine power generation system such that hydrogen purged from the hydrogen-cooled generator is fed to the fuel cell, the fuel cell configured to generate electricity from the hydrogen received from the hydrogen-cooled generator.
