Abstract
An electrical power system includes an electrical power generating system (EPGS); one or more constant power loads powered by the EPGS; and a power management and distribution (PMAD) center located between the EPGS and the one or more constant power loads, the PMAD center comprising a plurality of load management channels, each of the plurality of load management channels corresponding to a respective constant power load, wherein each of the plurality of load management channels comprises a load management function and a decoupling filter.
Claims20
An electrical power system comprising:
- an electrical power generating system (EPGS);
- one or more constant power loads powered by the EPGS;
- and
- a power management and distribution (PMAD) center located between the EPGS and the one or more constant power loads, the PMAD center comprising a plurality of load management channels, each of the plurality of load management channels corresponding to a respective constant power load, wherein each of the plurality of load management channels comprises a load management function and a decoupling filter;
- wherein each load management function comprises a positive rail contactor located on a positive rail, a negative rail contactor located on a negative rail, and an inrush-current limiting contactor.
A power management and distribution (PMAD) center comprising:
- at least one load management channel, the at least one load management channel comprising a load management function and a decoupling filter, the at least one load management channel configured to power a respective constant power load;
- wherein the load management function comprises a positive rail contactor located on a positive rail, a negative rail contactor located on a negative rail, and an inrush-current limiting contactor.
A method of operating a load management channel located in a power management and distribution (PMAD) center located between an electrical power generating system (EPGS) and a constant power load, the load management channel comprising a load management function and a decoupling filter, the load management function comprising a positive rail contactor located on a positive rail, a negative rail contactor located on a negative rail, and an inrush-current limiting contactor, wherein the inrush-current limiting contactor is in series with a resistor, and wherein the inrush-current limiting contactor and the resistor are in parallel with the positive rail contactor on the positive rail, the method comprising:
- during a power-up built-in test mode of the load management channel, opening the positive rail contactor, the negative rail contactor, and the inrush-current limiting contactor;
- during a pre-charge mode of the load management channel, opening the positive rail contactor, and closing the negative rail contactor and the inrush-current limiting contactor;
- during a load on mode of the load management channel, closing the positive rail contactor and the negative rail contactor;
- and
- during a load off/fault isolation mode of the load management channel, opening the positive rail contactor, the negative rail contactor, and the inrush-current limiting contactor.
An electrical power system comprising:
- an electrical power generating system (EPGS);
- one or more constant power loads powered by the EPGS;
- and
- a power management and distribution (PMAD) center located between the EPGS and the one or more constant power loads, the PMAD center comprising a plurality of load management channels, each of the plurality of load management channels corresponding to a respective constant power load, wherein each of the plurality of load management channels comprises a load management function and a decoupling filter;
- wherein each decoupling filter comprises an inductor in series with a parallel resistor and inductor located on a positive rail, and an inductor in series with a parallel resistor and inductor located on a negative rail.
A power management and distribution (PMAD) center comprising:
- at least one load management channel, the at least one load management channel comprising a load management function and a decoupling filter, the at least one load management channel configured to power a respective constant power load;
- wherein the decoupling filter comprises an inductor in series with a parallel resistor and inductor located on a positive rail, and an inductor in series with a parallel resistor and inductor located on a negative rail, and wherein the decoupling filter further comprises a capacitor connected between the positive rail and the negative rail.
