Abstract:The grid wiring diagram adopts the entire grid model of the dispatching and control cloud as the basis for graphic display and interaction. Aiming at the single display style of grid graphic and the deficiencies of visualization of power grid operational status of traditional power grid dispatching and control system, this study proposes a holographic display technology of power grid wiring diagram based on dispatching and control cloud, which is able to show the operation status of the power grid in different temporal, and achieve the historical scene inversion, real-time status monitoring and future operation mode analysis of the power grid, and then provide users with holographic display of various business scenarios based on graphics. This technology has been deployed and formally launched in the Area III of provincial and above power dispatching and control centers in multiple regions, meets the needs of displaying various business scenarios on the graphics, and improves the entire process control ability of the power dispatching and control centers.
