【摘要】：数字化变电站是以IEC61850通信规范为基础的,由电子式互感器等智能化一次设备、网络化二次设备分层构建,能够使变电站中各种智能电气设备之间实现信息共享和互操作的现代化变电站。在数字化变电站的发展过程中,各设备的出厂检验项目、方法、标准也不尽统一,更是没有一个完整的检修规范。如何规范各类设备的检验项目、方法、技术指标,统一技术标准,保证检修质量将成为现场技术人员面临的难题。本论文首先研究了基于IEC61850通信规范基础的数字化变电站内的结构体系、采用标准、具体设备结构、功能及特点等。结合江苏省淮安市首个数字化变电站110kV城南变电站,对典型缺陷、设备故障进行了深入分析,研究设备故障与时间关系的宏观规律,深入研究故障的发展过程,为制定数字化电气设备检修策略提供理论依据,针对目前数字化设备的检验方法、仪器和技术标准正面临着从传统型向光数字型转变的重大变革。通过对数字化变电站电气设备检修策略的研究,建立数字化变电站设备状态评估体系、形成检修策略,消除设备检修中的盲区,统一技术标准,保证检修质量,为开展数字化变电站设备的检修、检验提供重要依据。本论文可以解决现场检修人员的技术难题,为数字化变电站的稳定运行提供有力保障。
[Abstract]:The digital substation is based on the IEC61850 communication standard. It is constructed by the intelligent primary equipment such as electronic transformer and the network secondary equipment. Modern substations that can share and interoperate information among various intelligent electrical devices in substations. In the development of digital substations, the inspection items, methods, and standards of each equipment are not uniform. There is also no complete overhaul specification. How to standardize the inspection items, methods, technical indicators, and unified technical standards of all kinds of equipment, It will be a difficult problem for technicians to ensure the quality of maintenance. Firstly, this paper studies the structure system of digital substation based on IEC61850 communication specification, adopting standard and concrete equipment structure. Combined with the 110 kV Chengnan substation in Huai'an City, Jiangsu Province, the typical defects and equipment faults are deeply analyzed, the macroscopical law of the relationship between equipment faults and time is studied, and the development process of faults is deeply studied. In order to provide the theoretical basis for the maintenance strategy of digital electrical equipment, aiming at the inspection method of digital equipment at present, The instrument and technical standard are facing a great change from the traditional type to the optical digital type. Through the research on the maintenance strategy of the electric equipment in the digital substation, the equipment condition evaluation system of the digital substation is established, and the maintenance strategy is formed. Eliminating the blind spot in the equipment maintenance, unifying the technical standard, guaranteeing the maintenance quality, providing the important basis for the maintenance and inspection of the digital substation equipment. To provide a strong guarantee for the stable operation of digital substation.
