Abstract
In one embodiment, a method is used to provide dynamic electrical power management which may minimize the potential for overload conditions and may ensure that system performance limits are maintained. The method may dynamically limit the primary load system power draw in response to the net power draw of all other electrical power users on the aircraft which may ensure that the total power levels remain below critical limits. The method may also provide predictive controls to handle rapid load transients. Additionally, if vital functions are not being met, the method may shed other selected aircraft electrical loads which may ensure that adequate power is provided to the primary load system.
Claims25
A method for dynamically managing electrical load comprising:
- continually measuring total electrical load power consumption;
- and progressively and proportionately reducing electrical power to a primary load system whenever the total electrical load power consumption at least one of exceeds and is about to exceed a threshold electrical power limit.
A method for managing predicted electrical power load comprising:
- predicting a secondary load system electrical power load;
- and
- reducing electrical power to a primary load system to avoid exceeding a threshold electrical power limit.
A method for managing electrical power overload comprising:
- severing electrical power to a primary load system after a pre-determined time limit after a large secondary load system electrical power load occurred which was not anticipated and which resulted in an electrical power overload.
