摘要
在综合分析国内外对输变电设备状态在线监测与诊断技术的研究及开发应用现状的基础上,概括了当前普遍存在的一些共性问题;通过对输变电设备状态在线监测与诊断技术原理及方法和急待解决的技术问题的分析,提出集成分布式在线监测与诊断系统,输变电设备健康状态在线评估与剩余寿命在线预测的原理方案及解决存在的技术问题的思路;通过对在线监测技术与状态维修融合关系的分析,强调在线监测与诊断技术是实现从预防性维修过渡到状态维修的基础和不断研究并引入一些反映设备运行状态的新特征量的重要性。认为输变电设备状态在线监测与诊断技术是提高电网安全运行的第1道防御系统的关键技术之一,具有良好的应用前景。
The present status of research and development of power transmission and transformation equipment’s on-line monitoring and diagnosis technology in national and international were analyzed synthetically. Some general problems were summarized. By analyzing the principles and methods concerning to on-line evaluation and failure diagnosis of power transmission and transformation equipment, an integrated and distributed on-line monitoring system was put forwarded. The principles and schemes of on-line evaluation and residual lifetime prediction and the ways to solve some technical problems were also presented. By analyzing the interfusion of on-line monitoring and condition-based maintenance, the on-line monitoring and failure diagnosis were emphasized as the base to realize the transition from preventive maintenance to condition-based maintenance. The significance of studying and introducing some new characteristics concerning to the electrical equipments’ running condition were discussed. As a result, the on-line monitoring and diagnosis technology of power transmission and transformation equipment are regarded as one of the critical technology to improve the reliability of electric network, and its prospect is bright.
