Power grid dispatching and control system adopts CIM/G language which is the graphic description specification of power system as the standard of system graphic storage and exchange. For the problems of the complexity for displaying Web graphics in the power grid dispatching and control system with the CIM/G files transformed into SVG files and displayed by the Web browser and the delay for data refresh of Web graphical display and other issues

a Web graphical display technology for power grid dispatching and control system based on CIM/G is implemented. Web browser can directly parse and display CIM/G files

which ensures the consistency of areaⅠ and area Ⅲ in the graphic display. Through the heartbeat link mechanism of the Web front-end and backstage

the backstage change data is pushed to the Web front-end in the real-time

which improves the refresh efficiency of the Web graphical display. This technology has applied in the Web browser of area Ⅲ in multiple power grid dispatching and control system

which meets the demand of real-time monitoring the operation information of power grid and equipment through the Web browser in area Ⅲ.
