新一代电网调控系统分析决策中心多活数据同步设计与实现

Design and Implementation of Multi-active Data Synchronization in Analysis and Decision-making Center of New Generation Power Grid Dispatching and Control System

新一代电网调度控制系统采用"物理分布、逻辑统一"的体系架构,这就需要部署在云端服务器的分析决策中心通过多活方式来保障分析决策功能的可靠性,而多中心数据同步是中心间多活必需的关键技术。文中在中心多活需求分析的基础上,提出了多活数据同步软件框架,研究了数据强一致性同步、最终一致性同步、中心故障解除后的数据恢复等关键技术。研究成果在原型系统中得到了验证。

The"physical distribution and logical integration"architecture is utilized in new generation power grid dispatching and control system, which requires the analysis and decision-making center deployed in the cloud server to ensure the reliability of the analysis and decision-making function through multi-active way. The synchronization of multi-center data is the key technology among the multi-active centers. Based on the requirement analysis of multi-active centers, the software framework of multi-active data synchronization is proposed and the key technologies are studied such as strong consistency synchronization, final consistency synchronization of data, data recovery after centers faults are resolved, etc. The research results are verified in the prototype system.
