Abstract: The present invention discloses a three-dimensional man-machine interaction display and control method for power grid operation monitoring, which includes the following steps: drawing a picture in a two-dimensional plane by using a dual-buffer mechanism; reading the picture drawn in the two-dimensional plane, and drawing the picture in a three-dimensional space; detecting an interaction event in the three-dimensional space, and determining a type of a component in an operation panel; delivering the interaction event between the three-dimensional space and the two-dimensional plane, and processing the interaction event according to the component type; and reading the picture drawn by the component in the two-dimensional plane, and updating a corresponding image in the three-dimensional space. The present invention solves the problem of introducing the alarm images into the three-dimensional space.
