Patent attributes
A ring bus Shared Resource electrical System (SRS) has at least an essential electrical power ring bus and a critical electrical power ring bus as well as multiple SRS electrical power distribution platforms. Each SRS distribution platform includes one or more interconnected essential switchboards and two or more interconnected critical switchboards. Each essential switchboard is coupled through the essential electrical power ring bus to essential switchboards of two other SRS distribution platforms, and each critical switchboard is coupled through the critical electrical power ring bus to critical switchboards of two other SRS distribution platforms. Each SRS distribution platform directs power to one nominal load group and as well is configured to distribute power to a load group nominally supplied by another SRS distribution platform. One or more controller in each SRS distribution platform synchronizes the output voltage of SRS distribution platforms.
