Abstract
An electrical power system architecture and method for allocating power includes a power distribution bus configured to receive power generated by a first engine having a first generator and a second generator, a first set of electrical buses connected with the power distribution bus and associated with the first engine, and a second set of electrical buses configured to selectively connect with the power distribution bus.
Claims20
A method for restarting a non-operational engine of a flying aircraft, the method comprising:
- disabling a set of electrical loads associated with the non-operational engine from a power distribution bus except for a subset of essential electrical loads associated with the non-operational engine;
- selectively allocating a combined power output between at least two generator systems driven by at least one operational engine of the flying aircraft;
- and
- restarting the non-operational engine by way of a mechanically connected starter/generator supplied with at least a portion of the combined power output;
- wherein the selectively allocating the combined power output is based at least on a summation of a first power demand for a set of electrical loads associated with the operational engine, a second power demand for the subset of essential electrical loads associated with the non-operational engine, and a third power demand for the restarting the non-operational engine.

An electrical power system architecture, comprising:
- a power distribution bus configured to receive power generated by a first engine having a first generator system and a second generator system;
- a first set of electrical buses connected with the power distribution bus and associated with the first engine;
- a second set of electrical buses configured to selectively connect with the power distribution bus, including at least an essential bus, and associated with a second engine;
- and
- a share regulator configured to provide a set of share ratios values to the first generator system and the second generator system, and configured to receive an operational status of the second engine;
- wherein, upon receipt of non-operational status of the second engine, the power distribution bus is configured to selectively disconnect the second set of electrical buses except for the essential bus, and the share regulator is configured to provide the set of share ratio values to the first generator system and second generator system selected to enabled the first and second generator systems to share allocation of power generation sufficient to:
- energize the first set of electrical buses, energize the essential bus, and to restart the non-operational second engine.
