基于ECharts的电网Web可视化研究及应用

电网可视化是处理海量电力大数据、提高电网态势感知的重要技术之一。文中回顾了国内外电网可视化发展历程,以ECharts技术为核心,结合实际电网开发了一套电网Web可视化展示模块。主要有:基于SVG地理接线图和点线标记技术的电网动态潮流展示;基于指针表盘技术的电网运行状态实时监控;在动态拓扑技术基础上开发了基于电压信息的电网动态拓扑展示;基于力导向算法的电网弹性拓扑。该套可视化系统基于Web浏览器,兼容性好、维护成本低、易于开发,直观形象的展示了电网运行状态,为调度运行人员的决策和研究人员的工作提供了便利,工程应用广泛。

Research and Application of Grid Web Visualization Based on ECharts

Grid visualization is one of the important technologies in dealing with massive power large data and impro -ving situational awareness of the grid .This paper reviews the development process of grid visualization at home and a-broad.Combined with the actual grid and the core technology ECharts , a grid Web visualization display module has been developed .Following components are included in the proposed solution:the dynamic power flow display realized by SVG geographic wiring diagram and dotted line markers technology;the real-time monitoring of grid operation sta-tus based on pointer dial technology;the dynamic topology display of grid which is based on voltage information real-ized by dynamic topology technology;the flexible network topology of gird realized by force-directed algorithm .The set of visualization system realized by Web browser and the advantage of it like good compatibility , low maintenance costs, easy development , etc.It not only provides more intuitive and image operation state for the grid , but also pro-vides convinience for the decision-making of dispatching personnel and researchers work .
