PROCESS CONTROL EMERGENCY STOP, successful auto-reclose and subsequent false tripping HEAD SWITCH POWER LINES

摘要

A method for controlling an emergency shutdown, successful auto-reclosing (APV) and subsequent false tripping of the head switch (HS) transmission line, characterized in that with the appearance throw short-circuit current (fault) start counting HS tripping time delay, the control point its disappearance, and if the time counted by the time of closure fault current disappears, then conclude fault memory GW, since the disappearance of the fault current start counting time delay reclosing HS n When this control the appearance of the operating current cast, and if in the end of this time, it appears, have concluded a successful reclosure GW, since the advent of the working inrush start counting with the acceleration of tripping delay time in this case control the disappearance of the operating current, and if the end of the countdown operating current disappears, then conclude nuisance tripping HV power line.
