Abstract: A distributed fault management system includes at least one sensor associated with a fuel cell system and at least one first fault management computing device coupled to the at least one sensor. The at least one first fault management computing device is configured to receive data associated with a first fault condition. The at least one first fault management computing device is further configured to generate a resolution to the first fault condition and transmit at least one resolution command signal to at least one second fault management computing device. The at least one resolution command signal configures the at least one second fault management computing device to use the resolution to resolve a second fault condition in a similar manner.

Abstract: A fuel cell system is disclosed, which includes an anode recirculation loop including a fuel cell stack for generating power, a fuel supply device for providing a fuel to the anode recirculation loop, an air supply device for providing air to a cathode of the fuel cell stack, a voltage monitoring device for monitoring a voltage of the fuel cell stack, and an anode protection controller. The anode protection controller decreases a current drawn from the fuel cell stack by a predetermined amount whenever the voltage of the fuel cell stack drops below a predetermined voltage threshold and decreases a fuel flowrate provided to the anode recirculation loop based on the decreased current, so as to maintain a steam to carbon ratio in the anode recirculation loop above a predetermined steam to carbon ratio limit. A shutdown method for the fuel cell system are also disclosed.

Abstract: A power system includes a first power asset include a first power source and a first power controller. The first power controller includes a first filter configured to receive an error amount at a first frequency range and a second power controller includes a second filter configured to receive the error amount at a second frequency range. The first power controller is configured to instruct the first power source to produce a first amount of power, adjust the first amount of power based on the error amount received by the first filter until the error amount received is substantially zero. When the error amount received is substantially zero, the first power controller is configured to determine a first desired operating amount of power based on the first power source, and adjust the first amount of power based on the first desired operating amount of power.
