TLDR
In this article, a multi-spool gas turbine engine with at least first and second spools is used for electrical power generation. And the auxiliary generator/motor can operate in either a generator mode to extract power from its spool or a motor mode to inject power into the spool.Abstract:
An electrical power generating system is driven by a multi-spool gas turbine engine including at least first and second spools The first spool comprises a turbine and a compressor mounted on a first shaft; the second spool has at least a turbine mounted on a second shaft that is not mechanically coupled to the first shaft A main generator is coupled with one of the spools, and an auxiliary generator/motor is also coupled with one of the spools Speed control of each of the generators is employed for controlling operation of the engine The auxiliary generator/motor can operate in either a generation mode to extract power from its spool or a motor mode to inject power into its spoolread more
