Claims20
A gas turbine engine, comprising:
- a high pressure spool;
- a low pressure spool;
- and
- an electrical system configured to supply power in parallel to a first electrical bus and a second electrical bus, including:
- a first controller configured to control operation of the gas turbine engine;
- a second controller coupled to the first controller;
- a first electrical machine in mechanical communication with the high pressure spool;
- a second electrical machine in mechanical communication with the low pressure spool;
- a first inverter/converter controller coupled to the second controller, the first electrical machine and one the first electrical bus and the second electrical bus, and configured to provide electrical power to the one the first electrical bus and the second electrical bus under direction of the second controller;
- a second inverter/converter controller coupled to the second controller, the second electrical machine, the other of first electrical bus and the second electrical bus, and configured to provide electrical power to the other of the first electrical bus and the second electrical bus under the direction of the second controller;
- an energy storage system configured to supply power to and absorb power from at least one of the first electrical bus and the second electrical bus;
- and
- a converter controller coupled to the energy storage system, the second controller and the at least one of the first electrical bus and the second electrical bus, wherein the converter controller is configured to control the amount of electrical power supplied to the at least one of the first electrical bus and the second electrical bus from the energy storage system under the direction of the second controller;
- and to control the amount of electrical power received from the at least one of the first electrical bus and the second electrical bus and supplied to the energy storage system under the direction of the second controller.
