System and method for fault ride through

A power distribution system for providing fault ride through whereby the power distribution system continues to operate through periods of faults, wherein the system is in operative association with a source and a plurality of loads, the system comprising:

• a converter configured to receive a first power and convert the first power to a second power, the converter having a current demand threshold defining a maximum second power providable;
• a power distribution unit comprising a plurality of solid state power controllers and configured to provide the second power from the converter to the plurality of loads;
• one or more energy supplying units selectively coupled to at least one of an input terminal and the output terminal of the power distribution unit and configured to supply a third power;
• a fault protection unit operatively coupled to the converter, the power distribution unit, or both, wherein the fault protection unit comprises:
• a sensor configured to sense a current at an output terminal of at least one of the power distribution unit and the converter;
• a controller configured to:
• compare the sensed current with a corresponding threshold value of current;
• identify presence of a fault in at least one of the plurality of loads, the power distribution unit, and the converter based on the comparison;
• and
• activate a desired protection scheme to provide the fault ride through during the presence of the fault, wherein the fault ride through includes supplying the third power to the at least one of the input terminal or the output terminal of the power distribution unit such that the provided second power does not exceed the current demand threshold of the converter.
