Abstract

The invention discloses an intelligent switch feeder terminal with a traveling wave ranging function, which relates to the field of intelligent control and includes a signal acquisition and processing module, a control quantity output module, a traveling wave module, a processing module, a display module and a communication module with a superior; The signal acquisition and processing module is used to convert the measured voltage and current signals into digital signals and send them to the processing module. The voltage and current signals include line power frequency voltage and current signals and zero-sequence voltage and current signals; the traveling wave module uses The method is to receive the fault information sent by the processing module, then obtain the head time of the traveling wave current at the time of the fault, and send the head time of the traveling wave current to the processing module. The invention can accurately locate the fault point, and at the same time improves the accuracy rate of single-phase ground fault judgment, guides the operation and maintenance personnel to patrol the line, and shortens the time for finding and repairing the fault.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an intelligent switch feeder terminal with a traveling wave ranging function. Background technique [0002] Intelligent switch feeder terminal unit (FTU for short) has the functions of remote control, telemetry, remote signaling, remote adjustment, fault detection, etc., and is used to communicate with the main station of distribution automation to provide distribution system operation conditions, various parameters and monitoring Information required for control, such as switch status, power parameters, phase-to-phase fault, ground fault, fault parameters, etc., intelligent switch feeder terminals are also used to execute commands issued by the power distribution master station to adjust and control power distribution equipment . [0003] However, the existing intelligent switch feeder terminals only have the functions of fault isolation and rapid power supply restoration in ...
