电力继电保护术语（引电力资料网）1、主保护：满足系统稳定和设备安全要求，能以最快速度有选择地切除被保护设备和线路故障的保护。

2、高频闭锁距离保护：利用距离保护的启动元件和距离方向元件控制收发信机发出高频闭锁信号，闭锁两侧保护的原理构成的高频保护。

3、二次设备：是指对一次设备的工作进行监测、控制、调节、保护以及为运行、维护人员提供运行工况或生产指挥信号所需的低压电气设备。

4、重复接地：将零线上的一点或多点，与大地进行再一次的连接叫重复接地。

5、距离保护：是利用阻抗元件来反应短路故障的保护装置。

因阻抗元件反应接入该元件的电压与电流的比值（U/I=Z），即反应短路故障点至保护安装处的阻抗值，而线路的阻抗与距离成正比，所以称这种保护为距离保护或阻抗保护。

6、零序保护：在大短路电流接地系统中发生接地故障后，就有零序电流、零序电压和零序功率出现，利用这些电量构成保护接地短路的继电保护装置统称为零序保护。

零序电流保护就是常用的一种。

7、后备保护：是指当某一元件的主保护或断路器拒绝动作时，能够以较长时限（相对于主保护）切除故障元件的保护元件。

8、高频保护：就是故障后将线路两端的电流相位或功率方向转化为高频信号，然后利用输电线路本身构成一高频电流通道，将此信号送至对端，以比较两端电流相位或功率方向的一种保护。

9、电力系统安全自动装置：是指防止电力系统失去稳定和避免电力系统发生大面积停电的自动保护装置。

10、电力系统事故：是指电力系统设备故障或人员工作失误，影响电能供应数量和质量并超过规定范围的事件。

11、谐振过电压：电力系统中一些电感、电容元件在系统进行操作或发生故障时可形成各种振荡回路，在一定的能源下，会产生串联谐振现象，导致系统某些元件出现严重的过电压。

12、断路器失灵保护：当系统发生故障，故障元件的保护动作而断路器操作失灵拒绝跳闸时，通过故障元件的保护作用于本变电站相邻断路器跳闸，有条件的还可以利用通道，使远端有关断路器同时跳闸的接线称为断路器失灵保护。

1.主保护
满足系统稳定和设备安全要求,能以最快速度有选择地切除被保护设备和线路故障的保护.
2.后备保护
主保护或断路器拒动时用以切除故障的保护.
3.可靠性
可靠性是指保护该动作时动作,不该动作时不动作,
该动作时动作是可靠性中的信赖性,不该动作时不动作是可靠性中的安全性.保护该动作时不动作为保护拒动,保护不该动作时动作为保护误动.
4. 线路纵联保护
利用电力线载波.微波.光纤或专用辅助导线等通信通道互相传输两侧保护信息的快速动作保护.
5. 相位比较式纵联保护
利用通信通道互相传输故障电流的相位信号,两侧保护分别比较本侧与对侧电流相位,并根据相位差判别区内外故障的保护..
6. 电流差动纵联保护
利用通信通道相互传输被保护线路两侧电流瞬时值数据或电流模拟量频率调制的音频模拟信号,两侧保护根据本侧和对侧电流数据分别计算或求出保护线路上的电流差值,并根
判别内外故障个保护.
7. 远方跳闸式保护
利用通信通道把命令信号传输到对侧,对侧保护收到命令后直接跳闸的保护.
继电保护和系统安全自动装置的远方跳闸均由远方跳闸保护实现.。
