Hydrogen purge system, computer program product and related method

Various embodiments of the invention include systems, computer program products, and related methods for managing the purging of a hydrogen-cooled dynamoelectric machine (4). In various embodiments, a system is disclosed including at least one computing device (104) configured to perform the following: obtain an indication of a fault in an alternating current (AC) power supply (12) to a hydrogen-cooled dynamoelectric machine system (4); determine a reserve power characteristic of a reserve energy storage device (14) in response to obtaining the indication of the fault in the AC power supply (12); and extend a pre-purge cycle for the hydrogen-cooled dynamoelectric machine system (4) based upon the reserve power characteristic of the reserve energy storage device (14).
