Description

Technical Field

[0001] This invention relates to a method and apparatus for synchronizing power grid geographic data and equipment topology models based on geographic information map integration, belonging to the field of power system automation. Background Technology

[0002] Currently, the distribution master station needs to synchronize the main grid diagram and operation information with the regional power grid control system, send basic distribution network data to the indicator assessment system, integrate with the production management system diagram and model maintenance workflow, and integrate with other professional application systems in various regions. Simply relying on on-site engineers for manual or semi-automated processing results in low technical content and a huge workload, which affects the improvement of work efficiency and the deepening of the practical application of the system.

[0003] Therefore, the intuitive operation of integrating power grid geographic data, equipment topology models, and real-time equipment data onto a single geographic information map meets market needs, and the solution for synchronizing power grid geographic data and equipment topology models based on geographic information map integration has more vitality and room for promotion. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method and apparatus for synchronizing power grid geographic data and equipment topology models based on geographic information map integration, which can integrate power grid geographic data, equipment topology models and real-time equipment data on a single geographic information map.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0006] In a first aspect, the present invention provides a method and apparatus for synchronizing power grid geographic data and equipment topology models based on geographic information map integration, comprising the following steps:

[0007] The embedded GIS mapping engine monitors and records changes in devices within its field of view.

[0008] Obtain the device model change data transmitted from Zone 4.

[0009] The power grid geographic information system updates the power grid control system with changes in the distribution network model in an incremental manner.

[0010] The power grid control system will decide whether to reapply for model shading information based on changes in equipment within its field of view;

[0011] The power grid control system pushes real-time data, such as changing equipment topology coloring, to the embedded GIS mapping engine.

[0012] The embedded GIS map engine enables unified display and screen refresh of geographic connection maps.

[0013] Furthermore, the power grid geographic information system deployed in the third security zone provides an embedded GIS mapping engine to the power grid control system deployed in the first security zone. The power grid geographic information system and the embedded GIS mapping engine maintain real-time synchronization. The geographic data of power grid equipment in the power grid control system is accessed to the GIS mapping engine in a service manner to ensure that the power grid wiring diagram in the geographic information map of the power grid control system is updated in a timely manner.

[0014] Furthermore, the main parameters and topology of the distribution network equipment in the power grid control system all adopt and rely on the distribution network model in the power grid geographic information system. The power grid control system provides model update services and receives distribution network model change messages synchronized from the power grid geographic information system to the GIS model engine.

[0015] Furthermore, the power grid geographic information system updates the distribution network model and equipment topology to the power grid control system in an incremental manner to ensure that the distribution network models of the two systems are consistent.

[0016] Furthermore, after the power grid control system opens the geographic information map, it will immediately acquire the equipment within its field of view, then obtain model information through the equipment information for coloring processing, and push the equipment topology model information to the embedded GIS map engine. The embedded GIS map engine realizes unified display and screen refresh with the geographic wiring diagram.

[0017] Furthermore, during the scaling of the geographic information map, the display of devices within the field of view needs to meet the display specifications for devices within the field of view. At high field of view, key power grid equipment information needs to be displayed while hiding some power grid equipment with excessively small pixel widths, so as to keep the number of power grid equipment within the entire field of view within a basically controllable range.

[0018] In a second aspect, the present invention provides a device for synchronizing power grid geographic data and equipment topology model based on geographic information map integration, including a processor and a storage medium;

[0019] The storage medium is used to store instructions;

[0020] The processor is configured to operate according to the instructions to perform the steps of the method according to the first aspect.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0022] This application discloses a method and apparatus for synchronizing power grid geographic data and equipment topology models based on geographic information map integration. This method integrates power grid geographic data and equipment topology models onto a single geographic information map, enabling the display and application of both the equipment topology model and the power grid geographic data within the map through features such as geographic information map zooming, panoramic display, eagle-eye view, and graphic navigation. It solves the problems of low bandwidth and low work efficiency caused by the need for distribution master stations to synchronize main grid map modular data and operational information with regional power grid control systems.

[0026] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0027] Example 1:

[0028] This embodiment provides a method and apparatus for synchronizing power grid geographic data and equipment topology models based on geographic information map integration. The embedded GIS map engine is responsible for monitoring and recording the changes in equipment within the field of view during the zooming of the geographic information map, and pushing the list to the power grid control system. The power grid control system monitors the list of changes in equipment within the field of view in real time, obtains equipment topology coloring information from the database, and changes the topology coloring information of power grid equipment within the field of view in the geographic information map in real time. The new topology coloring is then displayed during the subsequent refresh of the geographic information map interface.

[0029] The specific steps are as follows:

[0030] Step 1: During the scaling of the geographic information map, the display of devices within the field of view needs to meet certain conditions. At high field of view, key power grid equipment information needs to be displayed while hiding some power grid equipment with excessively small pixel widths, so as to keep the number of power grid equipment within the entire field of view within a basically controllable range.

[0031] Step 2: The geographic information map needs to ensure that real-time topology coloring does not affect other main thread operations such as geographic interface refreshing and scaling, and does not cause main thread rendering stuttering or lag. Therefore, the topology coloring function for power grid equipment within the field of view needs to be completed by a separate thread.

[0032] Step 3: Monitoring of devices within the field of view is completed by the device monitoring thread of the shell program surrounding the geographic information map. It is necessary to dynamically monitor devices within the field of view and dynamically maintain the list of devices within the field of view during the scaling of the geographic information map.

[0033] Step 4: Create a separate device monitoring and push thread in the shell program surrounding the geographic information map. Obtain the device list maintained by the device monitoring thread through mutual exclusion by locking. Use an algorithm to quickly determine whether the device list has changed, i.e. whether the field of view has changed. If the field of view has changed, push the devices that need to be monitored to the power grid control system server for real-time monitoring.

[0034] Step 5: Create a service monitoring section on the power grid control system server to monitor the device list pushed by the power grid control system client in real time. If the device topology coloring information changes, the changed topology coloring information needs to be transmitted back to the power grid control system module client in real time.

[0035] Step 6: The power grid control system client needs to create a separate thread to receive topology coloring information, change the coloring information of power grid equipment within the field of view in the geographic information map in real time, and then display the new topology coloring during the subsequent refresh of the geographic information map interface.

[0036] The power grid geographic information system updates the distribution network equipment topology model to the power grid control system in an incremental manner, enabling real-time display and application of the power grid geographic information map. It can realize timely updates and synchronization of power grid equipment geographic data and equipment topology models between the power grid geographic information system and the power grid control system, and integrate power grid geographic data and equipment topology models into the same geographic information map, realizing the display and application of equipment topology models and real-time data in the power grid geographic information map.
