Abstract: A system for managing an electric power delivery system is disclosed that includes a set of remote intelligent electronic devices (lEDs) and a central lED. The remote lEDs may be configured to obtain information related to rotor angles, operating frequencies, rate of change of frequency, rotating inertia, and power consumption levels of loads and generators included in the electric power delivery system. The central lED may communicate with the remote lEDs to determine which loads and generators are associated with a sub-grid of the electric power delivery system and whether to disconnected certain loads or generators. Based on this determination, the central lED may direct the remote lEDs to disconnect loads or generators from the electric power delivery system, or to rapidly increase or decrease generator output as appropriate.

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.
