[0088] 2) Visualization module of large power grid intelligent dispatching map engine integrated with GIS;

[0089] Geographic Information System is an important spatial information system. Combining GIS with power network can enhance the intuitive visualization of power network, which is of great significance to realize the interactive service of intelligent dispatching of large power grid.

[0090] When building a visualization module for a large-scale intelligent dispatching map engine that integrates GIS, we first collect some spatial distribution geographic information such as "source-grid-load-storage" of the regional power system, unit information, power grid topology information, load information, energy storage information, operating status information, situation assessment index information, alarm information and control information, and combine the power system and regional information to build a power grid GIS system (or GIS map engine).

[0094] Specifically, a power grid GIS intelligent interactive unit is also designed to simulate and display the actual operating conditions of the power grid so that dispatchers can have a deep understanding of the power grid operating conditions.

[0095] 3) Power grid virtual electronic sandbox intelligent interaction module

[0096] A power grid sandbox simulation unit is built, which is the core part of the intelligent interactive module of the virtual electronic sandbox of the power grid. It can quickly analyze power grid accidents and simulate plans, preliminarily complete the combination of visual analysis technology and power grid simulation data analysis, and build a basic theoretical framework for visual analysis of power system simulation. A power grid simulation visual analysis application architecture with layers and three-dimensional modeling as the core is built, which belongs to the visualization part of the virtual electronic sandbox intelligent interactive module (the virtual sandbox needs to be presented using visualization technology; a variety of power grid simulation visual analysis applications have been developed, achieving a breakthrough in the visualization of power system simulation data, such as dynamic coloring and superposition display of multiple physical quantities, static and dynamic display of physical quantity numerical contour lines, linkage analysis of monitoring curves and geographic maps, and large-scale curve clustering analysis.

[0097] Furthermore, the intelligent interactive module of the power grid virtual electronic sandbox also provides an efficient and intelligent analysis and decision-making deduction platform, thereby meeting the growing business needs of stable analysis of the power grid and improving key technologies such as analysis, decision-making and risk resistance of complex power grids.

[0098] In order to further strengthen the online analysis capability of power grid characteristics, improve the global control over the operation status of the power grid and enhance the optimization and control capability of system resources, a new generation of power grid simulation application product with smooth functions, reasonable structure, convenient expansion, comfortable experience, and both ornamental, interactive and functional features has been established through design, development and hardware integration of virtual simulation, 3D animation, multi-touch, multimedia, system control, high-performance computing and other technologies - the power grid virtual electronic sandbox intelligent interactive module.

[0099] The intelligent interactive module of the power grid virtual electronic sandbox can easily conduct power grid accident analysis and plan simulation to avoid power grid accidents, thereby meeting the growing business needs of stable analysis of the power grid and improving key technologies such as analysis and decision-making and risk resistance of complex power grids.

[0100] Furthermore, if Figure 4 As shown in the figure, various information calculated by the big data platform is superimposed on the 3D simulation GIS operation scene of the power grid, so that the virtual information of the power grid operation situation is integrated with the real operation environment of the power grid, so that the dispatcher can more easily grasp the power grid operation situation and make better decisions. Specifically, virtual reality not only provides online operation conditions, but also provides the function of previewing the power grid operation status.

[0101] In summary, the intelligent interactive module of the virtual electronic sandbox of the power grid integrates the virtual information of the power grid operation status with the real operation environment of the power grid, improves the situation awareness of the power grid, and makes it easier to understand the operation conditions of the power grid. In the event of a fault, the power grid operation strategy displayed in virtual reality can realize the safe and stable operation of the power grid.

It can realize the intelligent interaction of the power grid based on GIS and virtual reality technology, and provide a technical basis for efficient visualization and panoramic situation awareness of the power grid.

[0103] 4) Large power grid intelligent dispatch voice interaction module

[0104] When the intelligent scheduling voice interaction module is implemented, the voice is first converted into text, and then the text is corrected, analyzed and other logical processes are performed through a deep learning framework to generate the required parameters; finally, the API is called, the parameters are input, and the search results are obtained.

[0105] Specifically, the large power grid intelligent dispatching voice interaction module mainly includes:

[0107] ②The intelligent dispatching knowledge base unit is a knowledge management module built based on the JCR knowledge content management standard interface concept and combined with the actual needs of domestic power companies. It can realize the accurate storage, version, permission, sharing, training and reuse of intelligent dispatching knowledge.

[0108] ③ Intelligent dispatching voice computing unit. Using voice dialogue recognition technology, the calculation programs for power flow, temporary stability, etc. in power system analysis can be called (such as by accessing the calculation and analysis unit in the big data platform). Specifically, it includes key steps such as preparation before program calling, output monitoring during program execution, and result display after program execution;

[0109] The intelligent scheduling voice computing unit belongs to the background management related content. The relevant data is stored in the big data platform, and the relevant data is called in the internal network through voice commands.

[0110] ④Supporting hardware equipment, including: data servers, computing servers, terminals;

[0111] ⑤Project implementation module, including installation, commissioning and technical training.

[0112] The intelligent dispatching voice interaction module can realize the rapid call of calculation programs such as power flow, temporary stability, and stability assessment in power system analysis, thereby improving the efficiency of large power grid analysis and decision-making.

[0113] At the same time, the intelligent dispatching voice interaction module improves the interaction efficiency between the dispatcher and the power grid, allowing the dispatcher to grasp the security situation more quickly. 5) Human-computer interaction subsystem for large power grid intelligent control.

[0114] Based on the spatiotemporal big data platform of large power grid intelligent dispatching, the visualization module of large power grid intelligent dispatching map engine integrated with GIS, the virtual reality intelligent interaction module and the large power grid intelligent dispatching voice interaction module, a human-computer interaction subsystem for large power grid intelligent regulation is constructed to realize the intelligent interaction, voice interaction, GIS interaction, virtual reality interaction and other functions between dispatchers and power grids, so as to ensure the intelligent, safe, stable and efficient operation of large power grid.

[0115] The following is combined with Figure 3-Figure 5 , a large power grid intelligent control interactive system integrating GIS and virtual reality in an embodiment of the present invention is described in detail.

[0116] like Figure 3 As shown, the data source of the large power grid intelligent control interactive system is the processed big data platform. Through different interactive channels provided by the human-computer interaction subsystem, the data is connected from the intelligent scheduling spatiotemporal big data platform to the map engine and the intelligent interaction module, thereby jointly realizing the intelligent control interactive function of the large power grid.

[0117] The large-scale power grid intelligent dispatching spatiotemporal big data platform provides massive data and computing support for the intelligent control interaction of the power grid.

[0118] Hadoop clusters can be divided into two major roles: management nodes (Master) and service nodes (Slave). In specific implementation, an HDFS cluster can be composed of two name nodes (NameNode) that are mutually active and standby, and more than three data nodes (DataNode). Among them, the name node (also known as the management node) acts as the master server to manage the file system's namespace and the application's access operations to the file system; the data nodes in the cluster (also known as the service nodes) act as slave servers to manage the stored data. In specific implementation, the server configuration of the large power grid intelligent dispatching spatiotemporal big data platform is listed in Table 1; the server connection diagram of the large power grid intelligent dispatching spatiotemporal big data platform is shown in Figure 3 shown.

[0119] Table 1 Server configuration

[0120]

[0121] In the conceptual diagram of the visualization module of the large power grid intelligent dispatching map engine integrated with GIS, various types of power grid information are integrated with the real geographical environment to reproduce the real operating environment of the large power grid and improve the dispatcher's situational awareness of the large power grid operating environment.

[0122] Figure 4 It is a virtual reality intelligent interaction module, which can realize geographic map drawing and display, data modeling, basic graphics engine, calculation data management, calculation call; power grid flow deduction (including: adjustment, setting, calculation, results and comparative analysis, etc.), safety and stability analysis, safety and stability strategy deduction, visual analysis, etc.

[0123] like Figure 4 As shown in the figure, the intelligent interactive module of the virtual electronic sandbox of the power grid includes a data file management engine layer, a computing engine layer, an application and data comprehensive analysis layer, and a human-computer interaction and visualization display layer; it can realize functions such as power flow deduction calculation, electromechanical transient calculation, electromagnetic transient calculation, dynamic safety assessment, auxiliary decision calculation, stability margin calculation, sub-network parallel calculation, and multi-task parallel calculation, and after comprehensive analysis, it can realize the deduction interaction and display of the sandbox.

[0124] Furthermore, by integrating virtual reality technology, the information such as power grid operation conditions, safety and stability level, and intelligent control strategies obtained from the big data platform (obtained after the big data platform processes the power grid data) will be combined with Figure 4 Superimpose and build a virtual reality intelligent interaction module. Use virtual reality technology to design a power grid control interface so that dispatchers can realize intelligent control of the power grid through the interface.

[0125] Specifically, in the conceptual diagram of the human-computer interaction system for intelligent control of large power grids, the operating status of each node or area of ​​the power grid is displayed on the GIS system in the form of a dynamic bar graph. When the stability of a node or area is insufficient, the system automatically gives an alarm and strategy, such as "The safety stability of power plant A is lower than 0.3, it is recommended to increase the output of unit X", and the height of the dynamic bar graph of the area decreases. The dispatcher places his hand on the bar graph and pulls it up, and the system issues an increase output command to unit X. After the output increases, the dynamic bar graph of the node or area rises, thereby achieving efficient control of the power grid.

[0126] like Figure 5 As shown in the figure, the large power grid intelligent voice interaction module is based on intelligent voice technology and realizes the processing of power grid information by the intelligent dispatching voice system.

[0127] At present, information and communication technology, big data technology, artificial intelligence technology, GIS and virtual reality technology are developing rapidly, making "autonomous driving" and intelligent interaction of power grids possible.

[0128] The large-scale power grid intelligent control interactive system integrating GIS and virtual reality in the embodiment of the present invention relies on advanced technologies such as information communication, big data, artificial intelligence, GIS and virtual reality to achieve deep integration and real-time interaction of real physical space, digital information space and human social space, and build a three-dimensional space-time empowerment system in which elements such as people, machines, objects, environment and numbers are mutually mapped, interact in a timely manner and efficiently collaborate, which meets the analysis needs of the real-time, expected and future states of the power grid, and improves the situational awareness capability of the power grid and the level of intelligent control of large power grids.
