Problems solved by technology

The disadvantage of this method is that when the circuit changes in real time, it cannot be linked and displayed in real time, and it does not reflect the actual working conditions. The scalability of real-time linked display for multi-dimensional information is relatively low.

Embodiment 1

[0065] like figure 1 As shown, step 100 is executed to obtain the logical connection relationship of the display devices from the database. The specific standard format definition is shown in Table 1.

[0067] Table 1 Equipment logical connection relationship table

[0068] Step 110 is executed to dynamically calibrate the display area by four-point coordinates according to the size of the actual screen. According to the actual size of the screen, adaptively calculate and alloc...

Embodiment 2

[0121] An automatic mapping method based on dynamic analysis of topological structure also includes a visual display method based on interactive information linkage.

[0122] Prerequisite Basic Guarantee Conditions:

[0123] 1. After the program is started, for the first time, the initial effect is displayed by collecting all the switch opening and closing information of the involved station area

[0124] 2. According to the gate position information carried by the data, whether the specific gate position change information is valid or not needs to be determined according to the corresponding strategy. For details, please refer to the specific constraints related to whether the data gate position information and the opening and closing reporting time are invalid.

[0125] 3. There is only opening and closing of one switch for each action, and only all lines related to the switch exist. In particular, when the line is dead, the switch will lose voltage and trip. Therefore, af...

Embodiment 3

[0170] An automatic graph forming method based on dynamic analysis of topological structure also includes manual adjustment graph-model automatic matching method.

[0171] For the topology structure, the combination of "pre-prediction and inference" is mainly used. Pre-topology (according to the actual scene, manually enter the topological relationship in the database, the structure is completely consistent with the topological relationship table structure at the inference place, which is convenient for later double tables Merge) has two main purposes: first, in the case of insufficient data accumulation, the automatic calculation topology is not yet ready for display, and the pre-topology is called; second, in the case of sufficient data accumulation, there are still a few The situation of power consumption or sporadic power consumption is a weak condition in the calculation process. In the case of suspending the output topology, the hierarchical relationship of the switch cor...

Abstract

The invention provides an automatic mapping method based on topological structure dynamic analysis, which comprises the step of acquiring a display equipment logic connection relationship from a database, and comprises the following steps of: dynamically calibrating a display area through four-point coordinates according to the size of an actual screen; performing row and column grid division in the display area by automatically searching the levels of the topological connection relationship and the types and the number of the devices contained in each level, and generating a topological connection relationship and automatically generating a corresponding graph through automatic calculation; setting the center coordinate of each switch as the center coordinate position of the unit grid according to the division of the display area and the number of the switches of the LL layer of the corresponding transformer area, and determining the coordinates of all the switches of the LL layer and the center coordinates of the grid in a one-to-one correspondence manner; automatically deducing the upper-level and lower-level coordinates of the corresponding coordinates of each switch of the LL layer according to the determined coordinates of each switch of the LL layer and the upper-level and lower-level relevance in the transformer area; and displaying the topological line based on four-point coordinate positioning.

Description

technical field [0001] The invention relates to the technical field of power grid system data processing, in particular to an automatic mapping method based on dynamic analysis of topological structure. Background technique [0002] The equipment information and topological connection relationship of the traditional distribution station area are mostly stored in the form of paper documents, and due to the lack of automation level, there is a lack of electronic information maintenance. If things go on like this, the actual connection relationship on site will be inconsistent with the existing saved data. The issue caused interruptions to system maintenance. [0003] With the continuous improvement of the level of the power Internet of Things, the scale of intelligent transformation of the distribution station area is expanding day by day. It is urgently needed and can realize the functions of topology search, dynamic coloring and automatic drawing on the visual master station...
