Abstract

A power generation/distribution system includes a RAM air turbine (RAT) generator and an emergency integrated control center (EICC) that selectively applies either primary power provided by a primary power source or emergency power developed by the RAT generator to an alternating current essential bus (AC ESS bus) for distribution to one or more essential loads. The EICC monitors the primary power and in response to a loss of primary power selectively disables the supply of power from the AC ESS bus to the essential loads and manages subsequent loading of the RAT generator by the essential loads.

First claim

The invention claimed is:

1. A power generation/distribution system comprising:
a primary power source configured to generate primary electrical power;
a RAM air turbine (RAT) generator configured to generate emergency electrical power when deployed into an airstream;
an emergency integrated control center (EICC) configured to transition a plurality of electrical loads from the primary electrical power to the emergency electrical power, the plurality of electrical loads includ…
