Application Strategy of Integrated Automation System in 110 kV Unattended Substation
Lu Juan-ni
[Abstract]The integrated automation system of the substation can incorporate all the control, signal, measurement and other details of the substation into the computer system, and can completely replace the traditional control protection screen. As we all know, the integrated automation system of substations is the key to the implementation of power grid dispatch automation. The work involves multiple disciplines and technical directions, and belongs to a highly complex project. This project is in real-time monitoring and fault handling. And so on, can produce obvious optimization effects. With the gradual maturity of substation automation technology in recent years, the effects produced in actual application cases are getting better and better. This article first explains the problems and corresponding solutions of the integrated automation system used in 110 kV unattended substations, and analyzes the application details of the technology, and finally puts forward the corresponding technical case application analysis, hoping to be able to optimize the follow-up related work Lay a stable foundation.

变电站综合自动化系统简称为“SA”,指的是在变电站工作中提高计算机智能设备的应用率,同时将现场工作数据向数字化转换,并分析出无法直接测量的数据,如谐波序电压等。不仅如此,其还能够对变电站的继电保护等工作和运行参数进行详细存储记录。

1.1 雷电入侵
变电站的电源线受到雷电的影响,会产生瞬态过电压的情况。若没有经过及时有效的处理,雷电进入电源系统中,必然会产生二次设备电源损毁的故障。在通信线引入雷电之后,引起的感应过电压会使通信线和设备之间产生电位差异;若后续直接用于串行通信接口,则还会引起微型计算机以及通信设备串行口损坏,若情况严重也会损坏微型计算机。……
