基于画像的变压器精细化管控策略研究
|
摘要
目前电力变压器精细化管控面临着"数据海量,信息缺乏"、状态评价主观性太强、辅助运维决策深度不够等问题,导致精细化管控策略较难定位工作方向、难以采取针对性措施。基于设备画像技术,形成了变压器设备全景标签;基于设备标签的二次建模,提出了基于标签关联分析的设备健康度评价优化方案,提出了变压器预警状态画像方案;在此基础上,形成了一种基于画像的变压器精细化运维策略。通过讨论此策略的应用效果,验证了此策略适合当前电网发展运行要求,具有较高的可行性、较强的可操作性。
At present,the delicate control of power transformers faces on the status of"a large number of data,but lack of information",subjective assessment of the status is too strong,and the depth of auxiliary operation and maintenance decisionmaking are not enough,resulting in a more difficult control strategy to locate the work direction,and difficult to take targeted measures.In this paper,based on the equipment portrait technology,apanoramic tag of transformer equipment is formed;based on the secondary modeling of equipment tags,an equipment health evaluation optimization scheme based on label correlation analysis is proposed,and a transformer pre-warning state portrait scheme is proposed.On these basis,an image-based transformer fine-grained operation and maintenance strategy is proposed.By discussing the application effect of this strategy,it is verified that this strategy is suitable for the current grid development and operation requirements,it has high feasibility and strong operability.
