Modeling and Application of Transformer Residual Life Based on CIM

信息集成技术作为未来电网中数据交互的重要支撑,将为未来智能电网的信息化发展奠定基础,并成为推动智能电网发展的重要方向。以变压器剩余寿命计算应用为依托,分析其需要的数据结构,并按照公共信息模型(CIM)标准为其建立相应的信息模型。在模型基础上,设计信息交互过程中的消息规范及传递信息内容,实现各系统之间对于变压器剩余寿命计算应用的信息交互。最终,以算例分析实现变压器剩余寿命计算,提出考虑加速老化的变压器剩余寿命计算方法,实现变压器剩余寿命计算的信息集成建模研究,并通过消息传递机制计算出相应寿命结果。

As an important support of data interaction in the future development of power system, information integra- tion technology lays the foundation of informationization in smart grid, and promotes the development of the smart grid. Bas^d on transformer residual life calculation application, this paper analyzes its data structure, and establishes its information model in accordance withthe Common Information Model （CIM） standard. Based on this information model, message specifications for information interaction are designed for information delivery in the application of transformer residual life. In the calculation example, algorithm considering the transformer accelerated aging is pro- posed. Modeling for information integration in the application of transformer residual life is achieved, and the results are delivered under the message mechanism.
