Abstract: Systems and methods are described herein to accommodate different settings associated with an inverter-based electric power generator and an inverter-based electric power generator for electric power generation within an electric power delivery system. The electric power delivery system may provide electric power generated by a bulk electric system to the loads via distributed substations using a first operating frequency. Moreover, the distributed substations may include inverter-based electric power generators to supply the electric power demand of downstream loads in an islanded configuration. That said, the inverter-based electric power generators may supply the electric power using a second frequency that is higher than the first frequency. Protective systems, positioned downstream from the distributed substations, may use different settings associated with the bulk electric system or the inverter-based electric power generators based on detecting the frequency of the supplied electric power.

Abstract: The present disclosure relates to systems and methods of sag in a power line. In an embodiment, a monitoring device may include a distance sensor and an operating parameter sensor. A processor of the monitoring device may acquire, via the distance sensor, a first distance measurement. The processor may acquire, via the operating parameter sensor, a first operating parameter measurement. The processor may provide an output signal indicating that the power line is sagging when a combination of the first distance measurement and the first operating parameter measurement exceed a first combined distance-operating parameter threshold.

Abstract: The present disclosure relates to a recloser control that provides autosynchronization of a microgrid to an area electric power system (EPS). For example, a recloser control may include an output connector that is communicatively coupled to a recloser at a point of common coupling (PCC) between the area EPS and the microgrid. The recloser control may include a processor that acquires a first set of measurements indicating electrical characteristics of the area EPS and acquires a second set of measurements indicating electrical characteristics of the microgrid. The recloser control may send synchronization signals to one or more distributed energy resource (DER) controllers to synchronize one or more DERs to the area EPS based on the first set of measurements and the second set of measurements.

Abstract: A condition-based monitoring system receives a plurality of measurements from sensors measuring mechanical and electrical aspects of a prime mover and a synchronous machine. The condition-based monitoring system determines a correlation between the mechanical measurements and electrical measurements to estimate parameters of the model. The condition-based monitoring system also updates the model as sensors obtain additional measurements during operation of the prime mover.

Abstract: A frequency tracking system may use shaft speed and electrical frequency to estimate a frequency of a monitored machine. The frequency tracking system may convert shaft speed to a mechanical frequency and blend the electrical frequency and the mechanical frequency together to determine an estimated frequency. The frequency tracking system may blend the frequencies based on an operating state of the monitored machine and the frequency sensors.

Abstract: A device to control a genset engine may use multiple feedback loops to provide a fast stable response to load changes. An outer feedback loop may receive frequency measurements and power measurements of a genset engine and determine a dispatch adjustment comprising a frequency setpoint based on the frequency measurements and power measurements. A middle feedback loop may comprise a double deadband droop filter that periodically generates a pulse based on the frequency setpoint and the power measurements. The middle feedback loop may update an inner loop setpoint based on the pulse. An inner feedback loop may alter a target fuel valve reference of the genset engine based on the inner loop setpoint generated by the second controller and a fuel valve droop.
