变电站远程访问架构的优化设计及实践

Optimal Design and Practice of Remote Access Architecture for Substation

分析了传统单体架构的远程访问模式在智能变电站大量推广的情况下存在的问题和局限性,介绍了面向服务的远程访问架构和基于容器的微服务架构的实现方式,在对3种架构的优缺点进行比对的基础上提出了基于不同业务需求的变电站远程访问的融合型架构。该架构即满足了I区实时数据的高实时性和稳定可靠,也满足了主子站软件架构的开放性,有利于业务扩展和维护,并通过工程试点验证,取得良好的效果,适应泛在电力物联网发展趋势,具有一定的推广意义。

This paper analyzes the problems and limitations of the remote access mode of traditional monomer architecture in the case of a large number of smart substations promotions,then introduces the implementation methods of service-oriented remote access architecture and container-based microservice architecture,and finally puts forward the integrated architecture of substation remote access based on different business requirements on the basis of comparing the advantages and disadvantages of the three architectures.The architecture not only meets the high real-time performance and stability of the real-time data in Zone I,but also meets the openness of the master and subsite software architecture,which is conducive to business expansion and maintenance.The project pilot verification is done to show that the proposed architecture has achieve good results,adaptable to the development trend of ubiquitous power Internet of things,thus having a certain significance of promotion.
