数字化变电站理论研究及其在上海电网的应用

Study of theory of digital substation and its application to Shanghai Grid

数字化技术已成为变电站技术的重要组成部分。目前,变电站内数字化技术运用尚存在各种局限性,数字化一次设备以及一、二次设备间的数字化通信技术的发展,使得按统一、完善的变电站自动化通信标准建设数字化变电站已成为可能。由于目前尚无完整的数字化变电站理论及其工程应用,上海电力设计院和上海市电力公司组建了"数字化变电站应用前期研究"课题组。文章重点介绍了该课题的主要研究成果,包括数字化变电站的定义与逻辑模型的理论研究、通信网络的构建,以及数字化变电站技术在上海电网中的分步实施方案。

The digitalization technique has been developed into an important component of the substation technique. Now there still exist various kinds of limitations in the operation of the digital technique within the substation, but the development of the digital primary equipment and the digital communication technique between the primary and secondary equipment have made possible the construction of a digital substation according to an unified and perfect substation automation communication standard. Due to the lacking of a comprehensive digital substation theory and its engineering application at the present time, Shanghai Electric Power Design Institute Co. , Ltd. and Shanghai Municipal Electric Power Company organized and set up a topic group of ＂The earlier stage study of the application of the digital substation＂. As key points, the chief achievements of the above-mentioned research topic are recommended. Namely： the theoretical study of the defi- nition of the digitalized substation and the logic models, step implementation scheme of the digitalized substation the construction of its communication network and the step by technique in the Shanghai Power Grid.
