Research On Voltage Sag Area Analysis And Visualization Based On SVG

As is known to all, various parts of the grid are connected with each other, any local failure or event is likely to be large effects on the grid. Therefore, the effective combination of regional power grid topology structure, system and equipment parameters and operational parameters of SCADA system, analysis user concern sensitive area can’t work normally because of the short circuit, and use SVG graphics formats widely used in power system, establish local visual display system, voltage sag graphical display domain analysis results is the research emphasis of this paper.Based on the static topology grid, this paper combined with the information of the SCADA system, and finished the grid voltage sag under dynamic topology domain analysis and the interface design of the related data, and show the effect of the sag area analysis results on the corresponding SVG image. Through parsing and processing of voltage sag domain analysis results, analysis the threshold value range of each route in in the domain, represented by the maximum and the minimum color as the color of the line, flashing, make the line color dynamic refresh, display the voltage sag area analysis results vividly, provides basis for the sensitive or important equipment to select site. It can realize the power grid dynamic security defense and reliable quality economic operation and provide necessary information for power grid design, planning and reconstruction.
