A Visualization Method of Power Flow Diagram

Abstract

The present invention provides a method for visualizing power grid flow diagrams, which includes the following steps: the WPF graphical interface framework continuously loads the grid power flow diagram data files that need to be rendered in real time; analyzes the grid power flow diagram data files to obtain the data structure of the power grid power flow diagram; The graph data structure adjusts the structure of the WPF graphical interface framework to combine the WPF graphical interface framework with the Direct2D module. The advantages are: the present invention provides a visualization method for power grid flow diagrams, which combines the Direct2D high-performance rendering technology under DirectX with the WPF graphical interface framework to replace the original milcore rendering technology of the WPF graphical interface framework, and realize a high-performance power grid power flow diagram The visual rendering method can effectively improve the rendering speed and ensure the fluency of displaying the grid power flow diagram on the large-screen device without lagging.

Description

technical field [0001] The invention belongs to the technical field of data visualization, and in particular relates to a method for visualizing power flow graphs. Background technique [0002] The steady-state distribution of voltage and power in a power system is called a power flow, and the circuit graph formed by distributing the voltage and power of the power grid through electrical symbols such as lines, nodes, and reactance components is a power flow diagram. Power flow diagram plays an important role in power grid operation. [0003] In the large-screen data visualization scheme of the power industry, it is necessary to visualize the power flow diagram. Customers in the power industry also have high requirements for the display performance of power grid flow diagrams. They not only require the fluency of display on large-screen devices with large resolutions, but also demand the timeliness of data visualization business data refresh. [0004] In the currently more ...

AI Technical Summary

Problems solved by technology

[0007] In the existing large-screen visualization scheme, a grid power flow diagram usually contains hundreds of various graphic elements such as circles and ellipses. Therefore, the native rendering technology of the WPF graphical interface framework is used to carry out the When rendering and displaying, due to the slow rendering speed, the grid power flow diagram may not be displayed smoothly on large-screen devices, and it is easy to appear stuck.
