摘要
为适应智能变电站发展要求,进一步提高变压器油中溶解气体在线监测系统自身的稳定性、准确性以及远程监控与管理能力,本文通过对装置采用现场自制载气、真空全脱气法、恒温控制等控制技术以及对VxWorks操作系统、SQLite嵌入式数据库、IEC61850通讯规约的研究,提出基于VxWorks的变压器油中溶解气体在线监测系统设计方案。首先讨论装置采用的新技术和硬件优化设计,然后介绍软件开发所用的关键技术以及系统的实现。现场应用表明:本装置运行稳定、准确性高、使用性强、易维护、功能高度集成以及支持远程监控和管理等功能。
In order to meet the requirements of intelligent substation development and further improve the stability, accuracy, re- mote monitoring and management of on-line monitoring system of dissolved gas in transformer oil device, we use the technologies of self-made carrier gas, vacuum degassing method, constant temperature control technology and combining with the research on VxWorks operating system, embedded database SQLite and IEC61850 communication protocol, put forward a design scheme of on-line monitoring system of dissolved gas in transformer oil device based on VxWorks operating system. Through the field appli- cation, the results show that： this device has some advantages, such as good stability, high accuracy of operation, more practica- bility, high level of functional integration, supporting remote monitoring and easy management.
