区块链技术在电力设备信息模型中的应用研究

Research on the application of blockchain technology in electric power equipment information model

IEC61850标准作为变电站综合自动化系统公认的国际标准,变电站信息模型数据、配置数据等采用XML进行描述,描述数据一般都是集中式的数据管理。该标准最重要的优势之一就是可实现设备的自动添加、删除、更新等操作,但设备变更记录追溯依赖于传统的数据库查询技术。集中式数据管理的安全性、变更记录的可信度都存在隐患和缺陷。文章利用区块链技术在去中心化、安全性、可信性方面的优势,将其应用于变电站信息系统模型,提高变电站的安全性和稳定性。

The IEC61850 standard is recognized as an international standard for substation integrated automation systems.Substation information model data and configuration data are described by XML.Descriptive data is generally centralized data management.One of the most important advantages of the standard is that devices can be automatically added,deleted,and updated.But device change record traceback depends on the traditional database query technology.There are hidden dangers and defects in the security of centralized data management and the credibility of change records.In this paper,the advantages of blockchain technology in decentralization,security and credibility are applied to the substation information system model to improve the safety and stability of the substation.
