基于数字孪生的GIS智能变电站健康评估及故障诊断模型

Health Assessment and Fault Diagnosis Model of GIS Intelligent Substation Based on Digital Twin

在现有GIS智能变电站中电力变压器、组合电器、开关柜三类主设备故障诊断技术研究的基础上,结合数字孪生技术,提出一种GIS智能变电站数字孪生模型建模方法。分析认为该模型可以同步显示实体变电站各仪表的数值,能基于变电站实时数据和历史数据进行健康评估及故障诊断,并在三维模型中对应空间位置显示,各设备运行状态一目了然,故障类型及位置指示准确。

Based on the research of fault diagnosis technology of power transformer, GIS and switch cabinet in the existing GIS intelligent substation, a modeling method of GIS intelligent substation digital twin model is proposed combined with the digital twin technology.Through analysis, this paper suggests that the model can not only synchronously display the data of each instrument of the substation, but also carry out health assessment and fault diagnosis based on the real-time and historical data of the substation and display the corresponding position in the three-dimensional model, so that the running state of each device is clear, and the fault type and position indication is accurate.
