    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.

    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 electrical power system may comprise an AC generator and a generator control unit (GCU) for varying AC output voltage of the AC generator. A DC bus may be connected to the AC generator via a Transformer Rectifier Unit (TRU) so that DC voltage on the DC bus is directly proportional to the AC output voltage. A battery may be connected directly to the DC bus. A control loop may be connected to receive battery current information and provide control signals to vary the AC output voltage so that battery charge may be maintained without battery damage.

    摘要： A power management system may employ a power source, a distribution system between the power source and electrical loads and an energy accumulator. The accumulator may comprise a plurality of energy processing blocks. Each block may have a limited number of energy storage cells connected in series to produce first voltage. A second higher output voltage from the accumulator may be achieved though integrated DC-DC, DC-AC and AC-DC conversion with intermediate boost of AC voltage through high frequency transformers. Bidirectional power flow may be achieved with high efficiency during charge and discharge of the accumulator. Secondary windings of the transformers may be connected with one another in series so that the accumulator can transfer energy between the distribution system and any one or all of the energy processing units in a fault-tolerant and efficient manner.

    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).
