In order to support line loss management work in the same period proposed by the State Grid Corporation of China,implement the complete coverage and full data acquisition of gateway electric energy for 35 kV and above voltage level,and provide the electric energy data from the gateway metering point in time for the line loss management,it's necessary to do deep research on the integrality of the data acquisition and the reliability of data transmission.By introducing a distributed message processing mechanism based on Kafka message queue,a distributed message system with high throughput,high performance and reliability is established. It adopts the message pub-sub mode,uses buffer queue based cyclic storage algorithm to ensure the reliable electric energy transmission and data collection based on the protection method for data replica,realizes the high efficiency and stability of the energy transmission in large-scale distributed applications,solves the difficulties in transiting from centralized data collection to distributed data acquisition,and supports subsequent research on massive data acquisition and application.At present,the system performs well and runs stably and reliably.%为支撑国网公司同期线损管理工作的全面开展,完成35 kV及以上电压等级关口全覆盖、全采集,及时向线损管理提供关口计量点电量数据,需要在电量数据采集的完整性及数据传输的可靠性方面进行深入研究.通过引入一种基于Kafka消息队列的分布式消息处理机制,构建一套具有高吞吐量、高性能并确实可靠的分布式消息系统,采用消息发布/订阅模式,基于副本数据保护方法,运用缓冲队列循环入库算法来确保其电量的可靠传输与数据归集,实现大规模分布式应用中电量传递的高效与稳定,解决从集中式向分布式采集架构过渡的难题,以支持后续海量数据采集应用的扩展性研究.目前,该系统应用良好,运行稳定可靠.
