A method for monitoring fuel quality of a power system used in transport is provided. The method includes a controller of the power system determining that the prime mover is actively running. The method also includes the controller monitoring an output of a water-in-fuel (WIF) sensor configured to measure an amount of water accumulated in a water collection reservoir of a fuel/water separator that separates water from fuel passing there through. Also, the method includes the controller determining an amount of fuel passing through the fuel/water separator. Further, the method includes the controller calculating a fuel quality score of the fuel based on the output of the WIF sensor and the amount of fuel having passed through the fuel/water separator. The method further includes the controller triggering different alerts based on the calculated fuel quality score.

Methods and systems for monitoring fuel quality and service issues for a power system used in transport

A generator set for a transport climate control unit is provided that is operable at a first frequency and a second frequency. The generator set includes a generator, a prime mover configured to operate at a first non-zero speed and a second non-zero speed that is less than the first non-zero speed, and a genset controller configured to control operation of the generator set. When operating at the first non-zero speed, the genset controller is configured to monitor a prime mover load parameter to determine whether the prime mover is approaching or has exceeded an overload or stall situation. The genset controller is configured to reduce the speed of the prime mover from the first non-zero speed to the second non-zero speed to prevent the overload or stall situation.

Prime mover load control on multi-speed generator set

A method for controlling a power system that powers a load is provided. The power system includes a prime mover, an electrical machine coupled to the prime mover, a battery source, an inverter coupled to the battery source, and a power system controller configured to control operation of the power system. The method includes monitoring a power demand on the power system from the load. The method also includes comparing the monitored power demand with a load threshold value. Also, the method includes determining that the monitored power demand is less than the load threshold value. Further, the method includes upon determining that the monitored power demand is less than the load threshold value: inactivating the prime mover, and instructing the battery source with the inverter to supply power to the load.
