摘要： A network protector relay controls a circuit breaker connected between polyphase feeder and network busses. A circuit samples polyphase circuit breaker current and network voltage to generate digital polyphase current and voltage samples. A microcontroller generates positive sequence current and voltage vectors from the current and voltage samples. A first trip algorithm trips the breaker in response to the positive sequence current vector being in a first trip region of a first trip characteristic with respect to the positive sequence voltage vector. The first trip characteristic is defined by a reverse trip setpoint and a first positive angle. A second trip algorithm trips the breaker in response to the positive sequence current vector being in a second trip region of a second trip characteristic with respect to the positive sequence voltage vector. The second trip characteristic is defined by the reverse trip setpoint and a second negative angle.

摘要： A method of protecting a section of a three phase power line uses superimposed current components in the power line to enable a local relay to detect operation of remote circuit breakers of remote relays in response to a fault on at least one phase of the power line. Line signal transducers output line condition signals indicative of voltage and/or current in the line near the circuit breaker, and a signal processor in the local relay processes the line condition signals to selectively produce a fault signal for opening its circuit breaker after taking account of remote circuit breaker operation.

摘要： A numerical comparator is disclosed. The numerical comparator employs numerical techniques based upon the behavior of the cylinder unit to compare phasors in real time. In one application of this invention, the torque signal generated by the numerical comparator, M.sub.k+1, is employed to determine whether a fault has occurred in a transmission line. Another application involves employing the output M.sub.k+1 to determine the direction of power flow in the transmission line. In yet another application, the output M.sub.k+1 is used to determine whether a voltage or current has exceeded a predetermined threshold.
