Abstract:Due to the inaccurate definition of power grid coverage, the visualization results are different from the actual data information results, which affects the visualization effect. Therefore, this paper proposes the research of power grid visual display based on 3D GIS technology. The active power is measured by beakers, and the load of each power supply area of the power grid is calculated. The three-dimensional GIS technology is used to convert the load data in the power grid coverage area into three-dimensional information with location label, and Apache Zeppelin is used to convert the power grid information in the database into target visualization effect. The test results show that the design method can realize the accurate visual display of power consumption type, overall power consumption, peak power, valley power and average power. The visual results are consistent with the actual data and information results, and the visual effect is good.
