Adaptive Method of Grid Power Flow Diagram Resolution Based on CIM/G Code

Abstract

The invention relates to a power grid tidal current chart resolution adaption method based on a CIM / G (Computer Integrated Manufacturing) specification. The power grid tidal current chart resolution adaption method comprises the following steps of scaling adaption, geographic background adaption and primitive adaption, wherein the step of scaling adaption comprises the following steps: according to an original power grid tidal current chart resolution and a current display equipment resolution, obtaining a scaling value; the step of geographic background adaption comprises the following steps:, sorting and numbering geographic background pictures, according to a set switching cardinal number, calculating the background number of the geographic background pictures, selecting one geographic background picture, calculating the scaling value of the geographic background picture, and carrying out uniform scaling; and the step of primitive adaption comprises the following steps: traversing and obtaining a primitive, and carrying out adaption processing to obtain the scaling value of the primitive, obtaining the visibility configuration of each primitive under the current scaling value, carrying out vector drawing according to the scaling value of a visible primitive, and refreshing to obtain and display an adapted power grid tidal current chart. Working efficiency is improved by the method, workloads are reduced, and the display usability, accuracy and attractiveness of the tidal current chart can be improved.

Description

technical field [0001] The invention relates to a resolution self-adaptive method realized based on CIM / G specification when displaying a power flow diagram. Background technique [0002] The power grid flow diagram uses the geographical image as the background, draws the graphic elements of each plant and station on the actual geographical location in the screen, and draws the line between each plant and station according to the real direction of the line, and shows the transmission direction of electric energy in the way of moving arrows. It can clearly and intuitively reflect the current trend of the power grid, power distribution, power grid operation status, etc., and is an indispensable image basis for dispatchers to monitor the power system in real time and guide dispatch work. [0003] The resolution of the geographical background in the flow chart and the proportional relationship of the graphic elements directly affect the accuracy and display effect of the picture...

AI Technical Summary

Problems solved by technology

This method increases the workload of dispatching maintenance personnel to draw pictures to a certain extent, and at the same time manually selects pictures that match the resolution, which also reduces the work efficiency of control personnel

When the dispatcher zooms in on the screen, the geographic background map will be distorted due to the mismatch of resolution, which will affect the accuracy and display effect of the screen information

Therefore, no effective solution has been proposed for the self-adaptive display of the same grid power flow diagram on hardware devices with different resolutions.
