Grid Visualization is one of the important technology in dealing with massive power large data and improve situational awareness of the grid. This paper reviews the development process of grid visualization. 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 status based on pointer dial technology; the dynamic topology display of grid which based on voltage information realized 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 provides a convenient for dispatching personnel’s decision and researchers work.
