Abstract
A bus conditioner for an electrical power system having at least one bus couplable to an electric power generation device driven by a prime mover includes a first energy storage device, a bi-directional power converter including a first converter input electrically connected to the first energy storage device and a converter output for connection to the bus, and a controller operatively coupled to the bi-directional power converter. The controller is configured to maintain a substantially constant load on the power generation device by commanding the power converter to divert excess power into the first energy storage device or use energy from the first storage device to provide power to the bus.
Claims20
A bus conditioner for an electrical power system having at least one bus couplable to an electric power generation device driven by a prime mover, comprising:
- a first energy storage device;
- a bi-directional power converter including a first converter input electrically connected to the first energy storage device and a converter output for connection to the bus;
- and
- a controller operatively coupled to the power converter, the controller configured to maintain a substantially constant load on the power generation device by commanding the power converter to divert excess power into the first energy storage device or use energy from the first storage device to provide power to the bus.
A method of improving engine efficiency for an engine drivably coupled to an electric power generation device, the method comprising maintaining a substantially constant load on the power generation device by providing energy from a first energy storage device to the bus or storing energy from the bus in the first energy storage device.
A method of improving efficiency for a power source operatively coupled to an electric power generation device, the method comprising maintaining a substantially constant load on the power generation device by providing energy from a first energy storage device to the bus or storing energy from the bus in the first energy storage device.
