Problems solved by technology

[0003] At present, the power flow diagram of the power grid mainly adopts a planar power flow diagram, which has the following disadvantages: because the power stations displayed on the power flow diagram are very dense, the connection lines between the power stations are very complicated, and there are often a large number of intersections. This makes it difficult for the dispatcher to clearly observe the distribution and transmission relationship between the stations; in addition, the existing power flow diagram has a single function, especially when there is an abnormality in a certain power supply line or station, it is difficult for the dispatcher to know in time This abnormal information and take corresponding solutions, thus reducing the operating performance of the power grid

Embodiment Construction

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The present invention provides a three-dimensional visual display method of grid power flow layered and partitioned, referring to figure 1 , including the following steps:

[0029] The spatial data of each power station site is obtained from the power system resource data, and the spatial data of each power station site is divided according to the type of the power station site, that is: the power station site includes three types, namely 500KV power plant site, 220KV power plant site and 110KV substation site; according to the conversion algorithm corresponding ...

Abstract

The invention provides a power grid current hierarchical partitioned three-dimensional visualized display method. The method comprises the steps that a power grid network topological three-dimensionalgeneral drawing is constructed; a site actual operation parameter list is established; and a control module has two control display modes, wherein the first control display mode is a voltage-level rack display mode, and the second control display mode is a partitioned rack display mode. The method has the advantages that (1) switching between a hierarchical display mode and a partitioned displaymode can be performed flexibly, and since association linkage operation is performed through n-level tree storage structures, system configuration complexity can be lowered, hierarchical display and partitioned display speed can be increased, and user usage experience can be improved; and (2) the method has the two display effects of hierarchical display and partitioned display, pertinent displayof connecting lines is realized effectively according to a user demand, the complexity of the connecting lines is lowered, a dispatcher can observe the power distribution relation among all station sites quickly, clearly and visually, and it is convenient for the dispatcher to make a dispatching decision efficiently.

Description

technical field [0001] The invention belongs to the technical field of grid visualization display, and in particular relates to a three-dimensional visualization display method of power grid flow layered partitions. Background technique [0002] Power grid power flow diagram is a picture that reflects the real-time operation status of the power system used by departments such as power planning, design, operation, and dispatching. It centrally displays the line distribution and power flow distribution between plants and stations, and is the main screen for dispatchers to monitor and analyze the power grid in real time. [0003] At present, the power flow diagram of the power grid mainly adopts a planar power flow diagram, which has the following disadvantages: because the power stations displayed on the power flow diagram are very dense, the connection lines between the power stations are very complicated, and there are often a large number of intersections. This makes it di...
