IEC60870-5-103规约在110kV可控电抗器控制装置中的应用

Application of IEC60870-5-103 protocol in the controller of 110 kV controllable reactor

介绍了IEC 60870-5-103通信规约在110 kV裂心式高压并联可控电抗器控制装置中的应用。首先简要介绍了变电站综合自动化系统(SAS)的局域网结构及IEC 60870-5-103通信规约(103规约)的特点,然后分析了可控电抗器的运行数据结构,给出了103规约在可控电抗器的控制装置中的具体实现方法。试验和现场运行表明,可控电抗器控制装置采用103规约能够与SAS系统进行可靠的通信,并且具有开放性。

This paper introduces the application of IEC 60870-5-103 protocol in the controller of the 110kV split-core type shunt controllable reactor. Firstly, characteristics of LAN of the substation automation system（SAS） and IEC 60870-5-103 protocol are introduced briefly. Afterwards, the structure of data from the controllable reactor is analyzed. According to the 103 protocol, the method to use it in the controller is introduced in detail. Now, the test from the field has proved that the controller with 103 protocol can communicate with SAS reliably, and the controller is open to other devices.
