Abstract

An example engine-driven power system includes: an engine; a generator configured to convert mechanical engine power to electrical power; first and second power subsystems configured to convert the mechanical or electrical power to first and second power outputs, wherein the first and second power subsystems are configurable to output the first and second power outputs simultaneously; an input device configured to control a load management priority, wherein the load management priority comprises at least one of an adjustable ranking, an adjustable balance, or bus voltage thresholds; and control circuitry configured to: control the first and second power subsystems to output the first and second power outputs based on first and second demands; and, in response to determining that a total demand exceeds a capacity, control the first or second power subsystems to reduce the power outputs or the demands based on the load management priority.

Dependent claims

An engine-driven power system, comprising:

an engine;
a generator configured to convert mechanical power output by the engine to electrical power;
a first power subsystem configured to convert at least one of the mechanical power or the electrical power to a first power output;
a second power subsystem configured to convert at least one of the mechanical power or the electrical power to a second power output, wherein the first power subsystem and the second power subsystem are configurable to output at least a portion of the first power output and at least a portion of the second power output simultaneously;
an input device configured to control a load management priority associated with the first power subsystem and the second power subsystem, wherein the load management priority comprises at least one of an adjustable ranking of the first and second power subsystems, an adjustable balance between the first and second power subsystems, or bus voltage thresholds for the first and second power subsystems;
and
control circuitry configured to:
control the first power subsystem to output the first power output based on a first demand;
control the second power subsystem to output the second power output based on a second demand;
and
in response to determining that a total demand, including the first demand and the second demand, exceeds a capacity of the engine, control at least one of the first power subsystem to reduce the first power output or the first demand or the second power subsystem to reduce the second power output or the second demand based on the load management priority.
