| 摘要: |
| 传统变压器状态监测组件IED较多，信息交互复杂，装置误报警率高，系统可靠性低。针对上述问题，提出了一种整合型变压器状态监测智能组件性能提升方案。通过对在线监测装置的硬件和软件功能集成及油色谱装置的优化设计，可有效减少变压器状态监测组件的IED数量和提高系统可靠性。基于Xenomai的Linux实时系统的研究，结合嵌入式SQLite数据库和Web Service应用技术，实现变压器在线监测系统的采集功能集成化和诊断流程标准化设计。所设计的智能组件整合了油色谱在线监测、铁心接地电流监测和特高频(UHF)局部放电监测等监测功能，已在重庆220 kV虎啸智能变电站中得到应用，效果良好，充分体现了未来智能监测组件向结构紧凑化、通信标准化和状态可视化的方向发展，具备较好的推广前景。 |

| Abstract: |
| The number of traditional transformer condition monitoring IED is more, the information interaction is complex, the device fault alarm rate is high, and system reliability is low. In view of the above problems, this paper proposes an integrated scheme of performance improvement for transformer intelligent condition monitoring. Hardware and software integration and oil chromatogram device optimization design can effectively reduce IED quantity and improve the reliability of the system. Based on the research of Xenomai real-time Linux operating system, and combined with SQLite embedded database and application of web service technology, online monitoring system for transformer of acquisition function integration, process standardization and model integration design diagnosis is realized. The design of the intelligent component integrated on-line monitoring of oil chromatogram, iron core grounding current monitoring, ultra high frequency (UHF) PD monitoring and other functions, has been used in the Chongqing Huxiao 220 kV intelligent substation, and achieved good results, which fully embodies the future of intelligent monitoring module to compact structure, communication standardization, state visualization the direction of development, with good prospects for promotion. |
