Abstract In this paper, a topology coloring and quadratic logic visualization method based on the calculation correlation of the overlapping area of the graph is proposed to improve the visual display and fault diagnosis functions of power monitoring system. The area and intersection area of the rectangle box of the primitives are firstly calculated, then the connection state between primitives are determined, and the attribute parameters of the associated primitives are set to their associated primitives ID. Finally, the associated states are displayed in different colors on the configuration screen. In this paper, the method is implemented in the supervisory control and data acquisition (SCADA) system. The actual case shows that the method can update the current display in the screen accurately and in real time, and has good visualization effect and high maintainability.
