Abstract: The present application provides a doubly-fed induction generator system for a multi-shaft gas turbine engine. The doubly-fed induction generator system may include a first doubly-fed induction generator in communication with a first shaft of the multi-shaft gas turbine engine, a first rotor of the first doubly-fed induction generator in communication with a converter via a first rotor bus, and a first breaker on the first rotor bus. The first doubly-fed induction generator acts as a generator or a motor depending in part upon the position of the first breaker.

Abstract: Methods and systems for operating a gas turbine engine including a fuel delivery system and a plurality of combustor assemblies are provided. The fuel delivery system comprises a primary fuel circuit configured to continuously supply fuel to each of the plurality of combustor assemblies during a first mode of operation and a second mode of operation. At least one secondary fuel circuit of the fuel delivery system is configured to supply fuel to each of the plurality of combustor assemblies during the second mode of operation. The secondary fuel circuit includes at least one isolation valve coupled in flow communication with each of the plurality of combustor assemblies. The at least one isolation valve facilitates preventing fluid flow upstream into the secondary fuel circuit during the first mode of operation. The fuel delivery system, using the isolation valve, replaces a purging system in the gas turbine engine.
