500kV双龙变电站监控系统的升级改造

Upgrade of Monitoring System for 500 kV Shuanglong Substation

为提高500 kV双龙变电站监控系统的运行可靠性和自动化水平,针对运行中暴露的问题,提出了监控系统改造方案。改造中采用了平滑过渡的方法,以新监控系统逐步替代原监控系统,对改造过程中可能出现的问题作了分析与应对。改造后的新监控系统运行稳定,达到了预期效果。

To improve the operational reliability and automation level of the monitoring system for 500 kV Shuanglong Substation,the upgrade scheme of the monitoring system is proposed so as to address the problems that occur in the operation.The method of smooth transition is applied in the upgrade,which gradually replaces the original monitoring system with a new one.The potential problems in the upgrade are analyzed and countermeasures are formulated.The new system runs steadily after the upgrade and achieves the goal.
