摘要： A device includes interface circuitry. The interface circuitry receives first input signals related to measurements of characteristics of electricity passing through a first power line. The device includes filtering circuitry that filters the first input signals to generate filtered data. The device also includes a processor that estimates an oscillation frequency of the filtered data via a time-domain frequency estimation method.

摘要： A method for compensating for communications channel delay asymmetry in a current differential protection system includes determining an apparent sampling clock offset for a communications channel, the apparent sampling clock offset between a first sampling clock and a second sampling clock configured within the current differential protection system. An apparent global positioning system (GPS) clock offset is determined for the communications channel, the apparent GPS clock offset between a plurality of GPS time stamps corresponding to the first and said second sampling clocks. A compensated clock offset is determined by subtracting the apparent GPS clock offset from the apparent sampling clock offset so as to cancel out a channel asymmetry component of deviation in the apparent GPS and sampling clock off-sets.

摘要： Systems configured to analyze and/or respond to faults detected during the operation of a power transmission system are disclosed. In one embodiment, a system includes at least one computing device adapted to monitor operation of a power transmission system by performing actions comprising processing operational data from a set of line phases in the power transmission system to detect a faulted line phase; opening a circuit breaker for the faulted line phase in response to detecting the fault; determining whether the fault is transient or permanent; and determining if an arc associated with the fault has been extinguished.
