Abstract: A method is provided for operating a power system (16). The method includes receiving an operator request for a propulsion direction change. The method also includes selecting a power boost map in response to the propulsion direction change request. The power boost map increases the power rating of a power source (34) of the power system. In addition, the method includes directing power into the power source. The method further includes regulating the power system and accelerating a power source speed according to the power boost map when the power is no longer being directed into the power source.

Abstract: A method for operating an electrical system (20) for a machine (10) is provided. The electrical system may include at least one power source (30) connected to a power-distribution network (21). The power-distribution network may include a first portion (26) with one or more power loads (34) connected thereto and a second portion (28) with one or more power loads connected thereto. The method may include repeatedly executing a load-priority cycle including operating in a first load-priority mode and subsequently operating in a second load-priority mode, during a power deficit. Operating in the first load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the first portion. Operating in the second load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the second portion.

Abstract: A method is provided for operating a power system (16). The method includes receiving an operator request for a propulsion direction change. The method also includes directing power into a power source (34) and reducing a supply of fuel to the power source while directing power into the power source. The method further includes basing a first threshold speed on a speed of the power source produced by directing power into the power source and increasing the supply of fuel to the power source when the speed of the power source falls below the first threshold speed.
