| Açıklama | Pilot RelayingAbstractIn this paper, pilot relaying “a modified form of differential relaying” is presented. The goal of the paper is to explain the outlines of pilot relaying fundamentals and its applications.Keywords: Pilot relaying, pilot wires, power line carrier, carrier current, microwave channel.1 IntroductionPilot relaying is an adaptation of the principles of differential relaying for the protection of transmission line sections. In a sense, it is a means of remote controlling the circuit breakers. The term “pilot” means that between ends of the transmissin line, there is interconnecting channel of some sort over which current and voltage information can be conveyed. Pilot relaying is used when high speed protection is required for all types of short circuits and for any fault location. This type of protection generally communicates the decision made by a local relay of one of the four types ( magnitude, directional, ratio, differential relays) to relays at the remote terminals of a transmission line.2 Pilot RelayingPilot relaying systems employ high-speed protective relays at the line terminals in order to ascertain in as short a time as possible whether a fault is within the protected line or external to it. If the fault is internal to the protected line, all the terminal breakers are tripped practically simultaneously, thereby permitting high-speed reclosing. If the fault is external to the protected line, tripping is blocked. |
