Abstract:
For use in estimating the direction to a disturbance source in a power system, an apparatus comprising:a voltage transducer coupleable to the power system and operative to produce a first signal representative of a voltage within the power system; a current transducer coupleable to the power system and operative to produce a second signal representative of a current within the power system; and a logic circuit coupled to the voltage transducer and the current transducer, the logic circuit being operative to calculate a disturbance quantity based upon the first and second signals, the logic circuit using the disturbance quantity to estimate the direction to the disturbance source, wherein the logic circuit further comprises: a computer readable storage medium operative to store a program, the program comprising an instruction code; and a processor operatively coupled to the storage medium and operative to perform a processing function based upon the instruction code, wherein the storage medium comprises a read only memory.
