Abstract: In an embodiment, a system includes multiple power management mechanism operating in different time domains (e.g., with different bandwidths) and control circuitry that is configured to coordinate operation of the mechanisms. If one mechanism is adding energy to the system, for example, the control circuitry may inform another mechanism that the energy is coming so that the other mechanism may not take as drastic an action as it would if no energy were coming. If a light workload is detected by circuitry near the load, and there is plenty of energy in the system, the control circuitry may cause the power management unit (PMU) to generate less energy or even temporarily turn off. A variety of mechanisms for the coordinated, coherent use of power are described.

Abstract: A system and method for identifying an earth fault in a resonant grounded medium voltage network that employs a REFCL compensation system. The method derives a zero-sequence real power from a phase voltage to ground on each phase and a current on each phase and aligns the zero-sequence real power in time with a magnitude of a zero-sequence voltage provided by the REFCL compensation system. The method determines when the zero-sequence real power and the zero-sequence voltage exceed predetermined thresholds. The method delays the magnitude of the zero-sequence voltage for a predetermined period of time when the zero-sequence voltage exceeds the threshold and determines that the fault is occurring when both the time aligned zero-sequence real power exceeds the threshold and the magnitude of the zero-sequence voltage exceeds the threshold for the predetermined period of time at the same time.
