摘要： An electronic device configured to switchover power from a primary source to an alternate source to maintain continuity of power supplied to a load bus. The electronic device includes one or more processors configured to identify availability of the alternate source using source monitoring in order to measure and calculate a tracking frequency for controlling a variable sampling interval of the one or more processors. The processors are configured to store signal samples and associated time stamps into a variable length buffer and store new sample values and associated new time stamps into the fixed length buffer. The processors are configured to determine attributes from samples of the alternate source using the tracking frequency. The processors are configured to execute a source switchover signal when the primary source is unavailable based by comparing load bus attributes to alternate source attributes at an estimated instance of switchover.

摘要： An example method of operating a power distribution system including a plurality of source and tie circuit protection devices coupled between at least one source and a protection zone is disclosed. The protection zone includes a distribution bus and a plurality of feeder circuit protection devices coupled between the distribution bus and a plurality of loads. The method includes determining an electric current flowing through each source and tie circuit protection device, determining whether any of the feeder circuit protection devices is outputting a ZSI blocking signal, and controlling operation of the plurality of source and tie circuit protection devices according to an enhanced partial differential protection scheme based on a combination of the determined currents through the source and tie circuit protection devices and the determination of whether any of the feeder circuit protection devices is outputting a ZSI blocking signal.

摘要： A protection and monitoring system, device, and method for an electric power system, including a capacitor bank having multiple strings in each phase, voltage and current measuring devices, and relays to protect this capacitor bank. Each string can have multiple capacitor units and each unit can consist of multiple capacitor elements. The method may include: determining steady state operating condition using the obtained current and voltages, calculating and storing present time impedance value of each string into memory, calculating the string per unit impedance incremental quantity, detecting capacitor element failure based at least in part on this incremental quantity and calculating number of failed capacitor elements for each event, accumulating the number of failed capacitor elements, and performing a protection action when healthy capacitor elements are subject to an overvoltage limit. The method may be inherently immune or otherwise insensitive to capacitor variations due to aging, temperature change, instrument transformers errors, inaccuracy in data acquisition, and inherent manufacturing unbalance.
