Electrical power system with automatic transfer switch failure protection

摘要

A data center includes electrical loads and an electrical power distribution system. The electrical power system includes a primary power source, one or more secondary power sources, and one or more groups of automatic transfer switches. Each automatic transfer switch and its corresponding load define a branch of the group. Each of the groups of automatic transfer switches includes a power cross-coupling system that cross-couple the branches in the group such that a load coupled to the output of the automatic transfer switch in one branch in the group is coupled to the output of an automatic transfer switches in the other branches of the group.

1. A data center, comprising:
a plurality of loads; and an electrical power distribution system, comprising:
a primary power source;one or more secondary power sources; andone or more groups of automatic transfer switches, wherein each of at least two of the automatic transfer switches comprises a first input coupled to the primary power source, a second input coupled to at least one of the one or more secondary power sources, and an output coupled to a corresponding one of the loads, wherein the automatic transfer switch is configured to switch the output to the load between the first input and second input, wherein each automatic transfer switch and its corresponding load define a branch of the group;wherein each of at least one of the one or more groups of the automatic transfer switches comprises a power cross-coupling system configured to cross-couple at least two of the branches in the group such that a load coupled to the output of the automatic transfer switch in at least one branch in the group is coupled to the output of an automatic transfer switch in at least one other branch of the group.
