数字化变电站在四川省电网的应用

Application of Digital Substation to Sichuan Power Network

数字化变电站是指变电站信息采集、传输、处理、输出过程全部数字化,其基本特征为设备智能化、通信网络化、模型和通信协议统一化、运行管理自动化。在变电站自动化领域中,随着智能化电气的发展,特别是智能化开关、光电式互感器等机电一体化设备的出现,变电站自动化技术即将进入数字化新阶段。论述了数字化变电站自动化系统的特征、结构、国内现状。全面介绍作为全川首座110 kV数字化变电站-南塔站数字化改造的具体实施方案,为全川开展数字化变电站改造提供必要的基础资料和建设方案。

A digital substation comprises the digitalization of the complete process level from data collection and transfer to data processing and output, Intelligence device, network communication, communication protocol and mode unification characterize a digital substation. With the development of electric intelligence, especially the optical, mechanical and electronic integration equipment such as the development of intelligent switch and optical instrument transformer, substation integrated automation system will enter into a new stage of digitalization. The features, the structure and the current domestic situation of the automation system in digital substation are described. The detailed implementation scheme of digital reconstruction in Nanta Substation is introduced, which is the first digital substation in Sichuan province and can provide the useful experiences and the reference to the renovation of digital substation.
