Embodiment 1

[0027] Such as figure 1 , 3 As shown in , 4, using the IEC61970 standard, with the geographical map of the main grid structure of the Changchun regional power grid as the background, the voltage values ​​of 500kV, 220kV, and power stations are displayed in the form of a three-dimensional surface map, and the current operating status is intuitively expressed through the color and concave-convex changes The overall distribution of voltage can quickly and intuitively find areas with high voltage and areas with low voltage.

[0028] Such as image 3 , 4 As shown, it supports screen switching from 3D surface graph to 3D histogram. Under the three-dimensional histogram, the voltage of each node in the main grid is represented by a column, and different colors and heights are used to represent the voltage level, which can visually express the relative voltage between different nodes.

[0029] The display of the three-dimensional surface map is similar to the topographic map in g...

Embodiment 2

[0049] Taking the geographical map of the main grid structure of the Changchun regional power grid as the background, the reactive power margins of each main plant are displayed in a three-dimensional histogram, including rotating reactive power margins (generators, condensers), fixed reactive power margins (capacitors, Reactor), total reactive power margin (sum of rotating reactive power margin and fixed reactive power margin). Each plant corresponds to a cylinder, and uses different colors and heights to indicate the relative size of the reactive power margin value.

[0050] For some key local areas, with the geographical map of its main grid as the background, the reactive power margin of the main power stations in it is displayed with a three-dimensional histogram.

Embodiment 3

[0052] Such as Figure 5 , 6 As shown, with the geographic map of the main grid structure of the major regional power grids as the background, the active transmission power on the 500kV and 220kV lines is displayed in the form of a three-dimensional pipeline diagram, and the thickness and color changes of the pipelines are intuitively represented. Distribution of line active transmission power.

[0053] Support screen switching between 3D pipeline diagram and 3D arrow diagram. In the three-dimensional arrow diagram, the arrows distributed along the line represent the active power flow on the line, the direction of the arrow indicates the direction of the active power flow, and the size, color and moving speed of the arrow indicate the magnitude of the active power flow. Under the three-dimensional arrow diagram, the overall active power flow of the whole network can be seen intuitively.

[0054] The 3D pipeline diagram is suitable for the visualization of undirectional line...

Abstract

The invention relates to a data real-time three-dimensional visual system of a power grid. The system is characterized by comprising four sub-systems, namely a voltage information sub-system, a reactive margin information sub-system, a tidal information sub-system and a stable information sub-system, wherein the voltage information sub-system supports picture switching between a three-dimensional surface chart and a three-dimensional cylindrical chart, represents a voltage of each node in a main grid frame by a cylinder under the three-dimensional cylindrical chart, and represents the voltage by using different colours and heights, so relative voltage among different nodes can be intuitively expressed, and the three-dimensional surface chart and the three-dimensional cylindrical chart can vary along with the real-time data refreshing of the power grid. By the invention, data in the power grid can be expressed quickly, efficiently and intuitively, so that a dispatcher can quickly know whether a problem exists in the current system and know the severity of the problem, and the dispatcher can know the running situation of the power grid wholly and macroscopically.

Description

technical field [0001] The invention relates to a three-dimensional visualization system for real-time data of a power grid, which is used for monitoring the operation of the power grid. Background technique [0002] The power system in operation continuously generates a large amount of data. In order to monitor its safety in real time, dispatchers need to pay close attention to these data and identify whether there are safety, stability and other problems in the system. If so, the location and location of the problem How serious is it. Although the traditional method of marking with numbers on the wiring diagram is fast and accurate, it cannot meet the needs of a large amount of data display, and the digital expression is not intuitive enough, and it is difficult to identify key information from a large number of numbers. Contents of the invention [0003] The purpose of the present invention is to provide a real-time three-dimensional visualization system of power grid ...
