摘要
阐述了数字化变电站综合自动化系统的原理结构,介绍了数字化技术在220kV变电站改造中智能单元、GOOSE、过程层合并单元采样、站控层光缆中的应用等。结合实例分析了改造中遇到的包括光电电压互感器、公用设备、光纤的使用、电压的并列与切换、间隔层联锁、运行维护等问题,提出了使用电压互感器采集单元、母线保护子站、GOOSE软件、光纤的标示等解决的方法。
This paper introduces the theoretical structure of digital substation integrated system. The application of digital technology in the innovation of 220 kV substation is introduced, including intelligent unit, GOOSE, merging unit, optical cable, etc. The resolutions on the problem encountered are analyzed based on real examples, suchasOVT, pubic equipment, usingoffiber-optic, side by side and switch of voltage, interlocking within or between bays, operation and maintenance. Measures are proposed, such as sampling unit ofOVT, subdevice ofbusbar protection, GOOSE software, label of fiber-optic, etc.
