导引线差动继电器是专为保护配电线路和输电线路而设计的高速继电器，主要用于40公里以内的短线路。它是开关设备继电器中速度最快的功率继电器，该方案的工作需要通信通道，以便它可以将系统电压和电流信息传送到控制部分 控制继电器的主要目的是远程控制断路器 控制继电器是用于高压输电线路，在两个或多个变电站之间传递“跳闸或不跳闸”继电器的作用是在出现故障时使断路器跳闸

导频通道 传输跳闸或不跳闸信号导频继电器 11使用不同的频道 • 线路调谐器用于通过电力线传输信号 信号将被调谐器耦合，使用陷波器，这种组合称为 (PLC) 电力线载波 • 电话线可用于传输信号 • 如果两个变电站之间的视线清晰，微波塔可用于传输跳闸信号 • 光纤电缆可用于信号传输 为了使用光纤电缆，T 线必须是短如果是的话光缆可以连接到线路两端的继电器

DISTANCE RELAY 距离继电器会响应电压与电流的比值，它会对阻抗和阻抗分量做出反应 距离继电器的特点 • 距离继电器可以从其位置检测到传输线中预设距离内的故障 • 由于电阻由电力线产生，总阻抗将是其距离长度的函数 • 距离继电器比较电压和电流，并计算阻抗

Guide line differential relays are high-speed relays designed to protect distribution and transmission lines, mainly for short lines up to 40 km. It is the fastest power relay in the switchgear relay, the work of the program requires a communication channel so that it can transmit system voltage and current information to the control part of the main purpose of the control relay is to remotely control the circuit breaker control relay is used for high voltage transmission lines, The function of passing "trip or no trip" relays between two or more substations is to trip the circuit breaker in the event of a fault

Pilot channels transmit tripping or non-tripping signals Pilot relays 11 Use different channels • Line tuners are used to transmit signals through the power line The signal will be coupled by the tuner, using a trap, this combination is called (PLC) power line carrier • Telephone lines can be used to transmit the signal • If the line of sight between the two substations is clear, Microwave towers can be used to transmit trip signals • Fiber optic cables can be used for signal transmission In order to use fiber optic cables, the T-wire must be short if so the fiber optic cable can be connected to relays at both ends of the line

DISTANCE RELAY The distance relay responds to the ratio of voltage to current, it responds to impedance and impedance components The characteristics of distance relay • Distance relay can detect faults within a preset distance in the transmission line from its position • Since resistance is generated by the power line, The total impedance will be a function of its distance length • Distance relays compare voltage and current and calculate impedance
