摘　　要：D5000智能电网技术系统全面采用基于电力调度数据网络的规约通道进行信息上传。电力调度数据网络系统是实现厂站自动化信息上送的重要途径,是确保电力生产工作有序开展的重要基础设施。随着地区电网规模的不断扩大和厂站接入数量的持续增加,电网调度控制系统对调度数据网的安全性、可靠性、稳定性等提出了更高的要求。针对这一背景提出了通过降低接入节点与汇聚节点数量的比例来优化地区调度数据网的拓扑结构,以提高地区调度自动化系统数据传输的稳定性和可靠性。这一优化措施为调度自动化系统的正常运行提供了有力支持,确保了地区调度控制工作的顺利进行,从而为地区电网的安全、稳定、可靠运行提供了保障。The communication channels for transmitting information from the D5000 smart grid technology system exclusively utilize protocols based on the power dispatch data network.The power dispatch data network system serves as a critical means for automated information transmission from substations,constituting essential infrastructure to ensure orderly power production operations.With the continuous expansion of regional power grids and increasing numbers of substations being connected,higher requirements are imposed on the security,reliability,and stability of the dispatch data network by the power grid dispatch control system.This paper proposes optimizing the topology of the regional dispatch data network by reducing the ratio of access nodes to aggregation nodes,thereby enhancing the stability and reliability of data transmission in regional dispatch automation systems.This optimization provides robust support for the normal operation of dispatch automation systems,ensuring the smooth operation of regional dispatch control work and safeguarding the safe,stable,and reliable operation of regional powergrids.
