mode thus when the heating system is required and turned on the system starts and provides the heat using the rejected heat from the gas turbine simultaneously the system produces electricity in parallel with the facility 39 s electric system and can reduce the amount generated by and purchased from the electric utility if the power produced is more than the facility is consuming the additional power can be delivered to the utility for sale or for credit against future or past purchases of electricity fig3 illustrates the preferred embodiment of the concept the solid lines terminating in arrowheads show fluid flow the dashed lines show control wires and the three solid lines between electric load 40 and breaker 38 and between breaker 38 and motor generator 30 show power wires breaker 38 which connects the electric load 40 to induction motor generator 30 is normally open as the electric load 40 is connected to the facility 39 s electrical system and or the electric utility grid it becomes a source of power for motor generator 30 to act as a motor and start the system motor generator 30 is mechanically connected through shaft 36 to the low speed shaft of gearbox 34 the high speed shaft of gearbox 34 is mechanically connected through shaft 32 to compressor 12 which is mechanically connected through shaft 24 to turbine 22 if breaker 38 was closed and no further actions were taken motor generator 30 would accelerate to its synchronous speed less its slip angle thus as an example if motor generator 30 had two poles and was operating on.
