Description

Technical Field

[0001] The present invention relates to the field of power system operation and maintenance, and in particular to a three-dimensional visualization method applied to a substation operation and maintenance system. Background Art

[0002] With the rapid development of power systems, substations, as important nodes for power transmission and distribution, have become increasingly complex and important in terms of operation and maintenance. Traditional substation operation and maintenance systems mainly rely on two-dimensional graphical interfaces and manual inspections to monitor the operating status and fault conditions of equipment. This method is inadequate in dealing with increasingly complex power systems, and there are several major problems:

[0003] 1. Information display is not intuitive: The two-dimensional graphical interface can only provide a flat equipment layout and data display, and cannot intuitively reflect the three-dimensional structure of the substation and the spatial position relationship of the equipment. It is difficult for operation and maintenance personnel to quickly and accurately understand the actual status of the equipment.

[0004] 2. Poor data correlation: It is difficult to effectively associate equipment operation data with its spatial location using a two-dimensional graphical interface. When looking for the source of a fault, operation and maintenance personnel need to repeatedly switch between different interfaces, which is inefficient.

[0005] 3. Difficulty in fault location: When a fault occurs, the two-dimensional graphical interface cannot intuitively display the location and surrounding environment of the faulty equipment. Operation and maintenance personnel need to make inferences based on text descriptions and simple graphics, which can easily lead to misjudgment and delays.

[0006] 4. Lack of dynamic display: Most traditional operation and maintenance systems can only provide static data display and cannot reflect the changes in the operating status of the equipment in real time. It is difficult for operation and maintenance personnel to grasp the dynamic information of the equipment in a timely manner, which affects the timeliness of fault handling.

[0007] Therefore, it is necessary to provide a new three-dimensional visualization method applied to substation operation and maintenance system to solve the above technical problems. Summary of the invention
