摘要： An ungrounded electrical power distribution system may experience a single line to ground fault. Such a fault may not disrupt operation of the system, but its presence may raise a risk of additional problems if left uncorrected. A system for progressively grounding the ungrounded system may be initiated when a line to ground fault is suspected. As grounding through successively lower impedance proceeds, fault current may increase and detection of severity of the line to ground fault may be more readily achieved, thus facilitating localization of the fault.

摘要： An ungrounded or floating DC electrical power distribution system may experience a single line to ground fault. Such a fault may not disrupt operation of the system, but its presence may raise a risk of additional problems if left uncorrected. A system for progressively grounding the ungrounded system may be initiated when a line to ground fault is suspected based on the voltage difference measured to a common chassis point. As grounding through successively lower impedance proceeds, fault current may increase and detection of severity of the line to ground fault may be more readily achieved, thus facilitating localization of the fault. Localization may be achieved through an analysis of direction of capacitive currents in isolatable zones of the system.

摘要： Methods for active power management, i.e., the power management method may be activated in response to changes in the supply and demand of power in a system, are disclosed. The power management method may use dynamically collected data reporting levels of electrical power utilized by systems while matching them to the available power. One embodiment of the present invention may be applied in smaller or medium sized systems. Another embodiment of the present invention may be implemented making use of additional aircraft resources, such as an integrated modular avionics (IMA) line replaceable unit (LRU) in larger sized systems. Both of these embodiments may make use of data collected from systems utilizing or generating electrical via the bus power control unit (BPCU) LRU, the data processing taking place either locally in the BPCU (small or medium sized systems) or in the IMA (larger systems).

摘要： An electrical power system may be provided with temporary power from a bank of supercapacitors connected to a bus of the power system. The supercapacitors may be charged from an output from a primary power source of the system during start-up of the power source. Output voltage of the primary power source may progressively increase and capacitor charging may occur at this progressively increasing voltage. Dedicated current-limiting devices are not required during charging. When temporary power is required the supercapacitors may be discharged sequentially in a series combination so that a high internal voltage of each capacitor is maintained and so that virtually all of the stored energy of the capacitor may be discharged to the bus at a usable voltage.

摘要： The present invention provides an electrical power distribution system that includes a first primary distribution panel (PDP) connected to a first source of electrical power and a second PDP connected to a second source of electrical power. The second PDP is connected to the first PDP by a conductor. A first ELCU receives signals corresponding to the flow of current through the first PDP to a load. A second ELCU receiving signals corresponding to the flow of current between the first PDP and the second PDP and a third ELCU receives signals corresponding to the flow of current between the second PDP and the first PDP. The first, second and third ELCUs protect the electrical power distribution system from a variety of fault conditions.
