GAS TURBINE ENGINE AND ELECTRICAL SYSTEM COMPRISING ELECTRICAL BUSES

摘要

A gas turbine engine includes an electrical system that includes a controller coupled to a first inverter/converter controller, a second inverter/converter controller, and a converter/controller that is coupled to an energy storage device. The system is configured to provide electrical power to a first electrical bus and a second electrical bus, from first and second electrical machines, under the direction of the controller. The converter controller is configured to control the amount of electrical power supplied to the first electrical bus and the second electrical bus from the energy storage system. The amount of electrical power received from the first electrical bus and the second electrical bus, and energy supplied to the energy storage system are under the direction of the controller.
