Abstract: Described are techniques for electrical grid origination determination using Power Line Disturbance (PLD) characteristics. The techniques include detecting a first PLD in a first voltage feed of a first power unit at a first time. The techniques further include comparing the first PLD to other PLDs aggregated from multiple power units. The techniques further include determining that the first voltage feed of the first power unit originates from a same source as a second power unit based on a similarity between the first PLD and a second PLD of the second power unit satisfying a similarity threshold and occurring within a same timeframe proximate to the first time. The techniques further include recording that the first power unit and the second power unit receive power from a same source.

Abstract: A signal-analysis-based process for detecting and correcting power feeds is provided. The process includes obtaining voltage waveform data for power feeds connected to a system, and determining for the power feeds, using the obtained voltage waveform data, at least one respective signal characteristic. Further, the process includes comparing the respective signal characteristics of the power feeds to ascertain at least one signal characteristic difference between the power feeds. Based on the at least one signal characteristic difference not exceeding at least one respective difference limit, the process determines that the power feeds are not separately-sourced redundant power feeds connected to the system, and based on determining that the power feeds are not separately-sourced redundant power feeds, the process initiates a corrective action to ensure that the system is connected to separately-sourced redundant power feeds.

Abstract: A technique for determining an electrical grid power source using a power line signal which includes electronic communication using a power line between a host device and power supply units (PSUs) on an electrical power grid. The host device can designate a PSU as a signal generator and designate remaining PSUs as signal receivers. The host device generates a signal onto the power line used by the PSUs. The signal is detected at each of the receivers on the power line. A response by one of the receivers to the host device, is in response to the detection of the signal at the receiver. An electronic communication device receives communication from the host device that the signal is detected by the receiver.

Abstract: A power distribution unit (PDU) of a disclosed embodiment comprises a configurable PDU architecture providing phase redundancy. The configurable PDU architecture comprises a switch bank having power inputs Phase A, Phase B, Phase C, and Neutral and providing respective phase outputs to respective connected loads. A switching control receives sense inputs and provides configuration controls to the switch bank. The switch bank switches in an alternate phase input when a primary phase fails providing phase redundancy and continued reliable operations with the loss of a single input phase. The PDU of one or more disclosed embodiments enables universal input power configurations including Single phase, Delta, and Wye configurations.

Abstract: Selective discharging of a rechargeable battery pack across a power supply system load is provided, which includes determining occurrence of a condition within the power supply system, the power supply system including a power supply circuit and a backup energy source. The power supply circuit receives main input power, and the backup energy source is operatively coupled to the power supply circuit to supply backup power to the system load when main power input to the power supply circuit is unavailable. Based on determining occurrence of the condition within the power supply system, a controller actively discharges a rechargeable battery pack of the backup energy source. The actively discharging includes controlling the power supply circuit to force discharging of power from the rechargeable battery pack to the power supply system load by suspending the main input power within the system from powering the system load.
