摘要目前,我国正在大力发展智能电网,智能终端在智能变电站中起着十分重要的作用,是实现电网智能化管理的重要手段。智能终端是在传统一次设备的基础上加装智能组件构成的,实现了对一次设备的智能化改造。
本课题研究的是智能终端与线路保护进行报文“交流”的过程,为了观察并抓取这两个装置之间进行交流的报文,搭建一个简单的实验平台,并同时用 SCL软件为装置编写虚回路交流信息,最后对装置施加故障量观察它们之间的报文交流并对报文进行分析。
通过做这个实验,观察到了智能终端与线路保护之间报文交流的对应性,智能终端对线路保护发送的指令报文都有一个完成动作的返回报文,这个实验对于了解智能变电站的工作流程有了重要的理论意义和实际应用价值。 20789

Title The Implement of Intelligent Terminal in Smart Substation
Abstract
At present, China is vigorously developing the smart grid, the intelligent
terminal plays a very important role in the smart grid. It is an important
means to achieve intelligent network management. The intelligent terminal
is a combination of equipment and intelligent components, it realizes the
transformation of primary equipment.
The topic of our research is the process of intelligent terminal and line
protection for packet exchange, in order to observe and grab packets
between the two devices, we built a simple experiment platform and we used
SCL to write virtual circuit devices to exchange information, finally the
malfunction was applied to the device in order to observe the packets
between them and then we analysed the packets.
By doing this experiment, it was observed the correspondence of the packet
exchange between the intelligent terminal and the line protection. The
intelligent terminal sends a recurrent message to the line protection after
it has done what it was required to do. This experiment has important
theoretical and practical value for us to know the workflow of the smart grid.
