摘要
变电站电力系统在运行过程中,可能出现各种故障和不正常运行状态。继电保护装置可以在故障发生时发出报警信号并控制断路器跳闸,隔离故障设备,避免事故扩大,对电力系统的正常运行起到至关重要的作用。目前,国内变电站保护装置的组屏方式主要有分散式组屏、集中式组屏和分散集中相结合的三种组屏方式,各种组屏方式均有其优缺点。以新建变电站和变电站自动化改造工程为例,阐述了组屏方式在不同情况下的应用。
Faults and abnormal states may be produced during substation power system operation. A relay protection de- vice can signal an alarm and control the circuit breaker tripping when a fault occurs,isolating faulty device and avoiding the accident expansive ,which play an important role in the normal operation of the power system. At present,the panel mode of substation relay protection device has three modes： the distributed mode, centralization mode and the combinative mode. All kinds of panel modes have their advantages and disadvantages. New substations and substation automation modification are used as the example to illustrate the application in different situations of the different panel mode.
