摘要
变压器的结构性能相对平稳,老化是一个渐进、缓慢的过程,在此基础上,分析了变压器的老化过程以及实现变压器老化状态在线监测的原理依据,针对变压器在不同老化状态下效率的不同,利用SCADA系统提供的海量的历史与实时的电气量测数据,探索变压器老化规律在线监测的可行性,提出了变压器老化规律在线监测的一种新方法。基于随机过程理论,建立由电气量测数据有机表达的反映变压器老化状态的运行性能指标,实现对变压器老化程度与潜伏性故障的在线监测。
The structure of the transformer performance is relatively stable,aging is a gradual slow process,on this basis ,this paper analyzes the aging process of transformer and the principle achieving transformer aging condition online monitoring, according to different efficiency of transformer in different aging conditions, make use of vast amounts of historical and real-time electric parameters measurement data from SCADA,this paper explores the feasibility of aging law transformer on-line monitoring and puts forward a new method to research it.Based on the theory of stochastic process,we establish the operation performance metrics reflecting the transformer aging condition expressed by electric parameters measurement data,realize online monitoring of transformer aging degree and the latent fault.
