Gas turbine generator load level control system

A method comprising:

• rotationally driving a generator with a gas turbine engine;
• outputting electric power to a load bus with the generator to supply a load demand present on a the load bus;
• energizing a first load with the load bus and increasing an output torque demand of the gas turbine engine in accordance with an increase in the load demand on the load bus;
• cycling between energizing, with the load bus, the first load and a second load to substantially maintain the increase in the load demand on the load bus as the first load and the second load are sequentially energized and deenergized;
• and
• maintaining the output torque demand of the gas turbine engine substantially unchanged during the cycling.

A system comprising:

• controller circuitry configured to:
• monitor an operational parameter of a gas turbine engine;
• control a load demand of a generator to output electric power on a load bus, the generator rotatably driven to generate electric power by output torque of the gas turbine engine;
• control energization and de-energization of a first load as a load on the load bus;
• control energization and de-energization of a second load as the load on the load bus;
• transition between the load on the load bus being the first load and being the second load;
• and
• maintain the load on the load bus substantially unchanged by timing the transition between the load on the load bus being the first load and being the second load.
