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
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 and the essential bus.

A method for allocating power in an electrical power system architecture, comprising:
- determining an operational status of a first engine system;
- and
- in response to determining the first engine system is non-operational:
- selectively disconnecting a first set of electrical loads associated with the first engine system from a power distribution bus except for a subset of essential electrical loads associated with the first engine system;
- providing a set of share ratio values to a second operational engine system having at least a first generator and a second generator;
- and
- operating the first and the second generators in accordance with the set of share ratio values such that the first and the second generators allocate a desired combined power output to the power distribution bus sufficient to energize a second set of electrical loads associated with the second engine system and the subset of essential electrical loads associated with the first engine system.
