随着智能电网信息化技术的快速发展,已稳定运行多年的FNET/GridEye软件系统已经无法适应未来的发展。针对这种情况并结合最新的电力实时大数据(以同步向量数据为主)开源项目OpenPDC/OpenHistorian设计了基于分布式架构的新一代系统。系统由前端集群、后端集群和系统调用组件三部分组成,具有系统扩展性强和可靠性高的特点。前端集群中的每台OpenPDC服务器负责接入一定数量的同步向量采集设备,并在其中运行不同的电网事件触发器插件。当触发器探测到电网事件后会以组播方式通知位于后端集群中的系统调度组件,此组件负责从OpenHistorian中加载窗口数据后,运行对应的分析应用程序。针对已投运系统的数据吞吐量测试、两年多的稳定运行和不断添加前端设备和后端应用证明了新系统设计的先进性。
With the rapid development of smart grid information technology, the FNET / GridEye software system, which has been operating stably for many years, has been unable to adapt to the future development. In response to this situation and combined with the latest power real-time big data (based on synchronous vector data) open source project OpenPDC / OpenHistorian designed a new generation system based on distributed architecture. The system consists of front-end cluster, back-end cluster and system call component. It has the advantages of strong scalability and high reliability. Each OpenPDC server in the front-end cluster is responsible for accessing a number of synchronous vector collection devices and running different grid event triggers plug-ins there. When a trigger detects a grid event, it multicasts the system-scheduling component in the back-end cluster. This component is responsible for loading the window data from OpenHistorian and running the corresponding analysis application. For the data throughput of the system has been put into operation, more than two years of stable operation and the continued addition of front-end equipment and back-end applications proved the advanced system design.
