The invention relates to a graphical display method and a graphical display system for power grid safety evaluation indexes. The method comprises the steps of collecting the power grid safety evaluation indexes and generating a calculation result table; performing numeralization of calculation result information on the calculation result table; and displaying the numeralized calculation result information based on a pre-constructed graph. According to the method, a graphic calculation result index display system is relatively intuitive, information is displayed on one graph, the information ismore centralized. Meanwhile, an overall result index coefficient can be given to a current operation mode.
