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.
