Abstract
Systems and methods are provided for continuously and automatically monitoring, controlling, and combining shore-based AC power sources for waterborne vessels while the vessels are at dock or in port. The systems can allow a one or more shore AC power AC to power the entire vessel, and automatically and safely join multiple power sources to power a single higher-current-capacity electrical distribution bus on the vessel. The systems can automatically monitor and evaluate the characteristics of multiple shore power sources to determine when it is possible to safely combine the sources. Also, the systems can recognize the disconnection/disablement of a shore power source, and can un-combine that power source from the other power sources feeding the system. The systems can automatically evaluate the phase, current and voltage of multiple AC sources, and combine the sources only after a specific set of conditions are satisfied.
