摘要
微机保护装置是供配电系统的核心部件,其负责开关柜间隔的保护、控制、测量,并能直观指示断路器的位置、状态信息.电力监控系统则是通过对各级配电设备运行数据及状态信息的采集、分析、判断,以全景图像的形式实现对开关柜的遥测、遥信、遥控、遥视、遥调功能.通过对某机场长期运行进行分析,合资品牌微机保护装置的可靠运行周期约为10～12 a,适时进行更新改造对于配电系统的运行安全极为重要.文章通过对某机场T3中心配电室微机保护装置更新改造以及后台监控系统整合分析,实现各级配电室保护装置型号一致、通讯规约一致、监控系统一致,以降低维护成本,降低故障率,提高设备的可靠性.
Abstract
The microcomputer protection device is the core component of the power supply and distribution system.It is responsible for the protection,control,measurement of the switchgear interval and can visually indicate the position and status information of the circuit breaker.the power monitoring system collects,analyzes,and judges the operation data and status information of various levels of distribution equipment,and realizes the functions of remote sensing,remote signaling,remote control,remote viewing,and remote adjustment of the switchgear in the form of panoramic images.based on the long-term operation analysis of a certain airport,the reliable operating cycle of the microcomputer protection device of the joint venture brand is about 10-12 years.Timely updates and renovations are extremely important for the safe operation of the power distribution system.this article attempts to achieve consistency in protection device models,communication protocols,and monitoring systems at all levels of the T3 central distribution room of a certain airport by updating and transforming the microcomputer protection device and integrating the backend monitoring system,in order to reduce maintenance costs,reduce failure rates,and improve equipment reliability.
