多源异构电网运行时标量测数据接入方案设计

海量准实时数据服务平台是电网运行时标量测数据集中存储的场所；为了满足电网调度自动化、计量自动化等电网运行数据的接入需求,提出一种多源异构电网运行时标量测数据接入方案;该方案综合采用关系数据库和实时数据库存储数据,结合实时数据库存储数据的测点特性定义了电网时标量测数据存储命名规范,通过配置服务实现数据接入任务的启停控制和运行状态监控,使用接入调度器调度接入插件执行接入任务并引入主备冗余技术保证调度器的高可用;方案引入组件化程序设计思想,通过可插拔、易扩展的插件设计满足多源异构数据的接入需求;方案在南方电网公司海量准实时数据服务平台建设项目中得到实际应用,很好地满足了南方电网运行时标量测数据的接入需求。

Scheme Design for Mass Time Scalar Data Accessing of Power Grid With Characteristics of Multi-source Heterogeneous

The service platform with mass real time data is the place where the time scalar data of power grid are stored centrally in. In order to meet the demand of power grid dispatching automation and measurement automation, a data access scheme for multi-source heterogeneous grid operation is proposed. The scheme uses relational database and real-time database to store data, define the storage standard of scalar measurement data based on the characteristics of data points stored in real-time database, through the configuration service to achieve data access tasks start and stop control and operation status monitoring, the access scheduler is used to schedule the access plug-in to complete the access task, and introduce the main and standby redundancy technology to ensure the high availability of the scheduler. The concept of component programming is introduced, and the access requirements of multi-source heterogeneous data are met by pluggable and expandable plug-in design. The scheme has been applied in the construction project of massive quasi real time data service platform of China Southern Power Grid Company. It can well meet the demand of China Southern Power Grid operating scalar measurement data access needs.
