What is a smart grid?

In fact, there is currently no unified definition of smart grid. Experts in various fields have elaborated on the connotation of smart grid from different angles. With the development of research and practice, Continuously refine it in depth.

At present, smart grids are mainly used to realize panoramic operation information, networked data transmission, dynamic security assessment, refined dispatching decisions, automated operation control, coordination optimization, and to ensure the safety and reliability of power grid operation. Flexible and coordinated, high quality and efficient, economical and green.

First of all, sensors must be used to monitor the operating status of key equipment such as power generation, transmission, distribution, and power supply in real time.

Then the obtained data is collected and integrated through the network system.

Finally, through data analysis, mining, and visual presentation, the optimal management of the entire power system operation is achieved. Today we see how "intelligent" the smart grid is from a visual presentation!

Selected from Hightopo substation visualization case----

Hightopo power three-dimensional visualization scene satisfies multi-dimensional presentation of substation operation and maintenance scenarios, and enables real-time monitoring of substation operation status. interconnection of maintenance equipment, control systems and information systems. Strengthen the full status perception and control of substation equipment, enhance the substation's safety production guarantee capabilities, and improve the level of lean management of operation and inspection. You can control the overall situation without leaving home

Using lightweight 3D modeling technology to restore the appearance modeling based on CAD drawings, bird's-eye view, equipment three-view and other data on the substation site, and realize interactive modeling through HT The Web 3D scene can be zoomed, panned, and rotated, and each device in the scene can respond to interactive events. It also provides a solution that combines GIS maps to display all power grid points, allowing a large amount of point data to be presented on a three-dimensional map.

Let's take the smart substation system as an example to analyze "intelligence" to the end~

Global monitoring of operating status

Through the comprehensive analysis of multi-source data, in The map displays substation normal, warning, alarm and other status information in real time, allowing you to quickly locate the substation that issued the warning.

Visualization of voltage and current loops

Use 3D visualization technology to display the entire circuit direction of voltage transformer and current transformer power supply, combined with technology The sensing element simulates the current flow effect to realize the monitoring, measurement, control and regulation of the operating conditions of primary equipment (transformers, circuit breakers, isolation switches and other equipment directly used to produce and use electric energy).

Intelligent inspection

Through the intelligent inspection system, alarm information is sent out according to the alarm equipment, and the target location is quickly reached. Inspection videos and alarm information can be viewed in real time, and staff can promptly Be aware of and handle accordingly.

Real-time monitoring of equipment

Display the status of focused equipment on the page, using icons of different colors to represent different equipment statuses, namely normal [blue], abnormal [yellow], and severe Fault [red]. Once the equipment status is abnormal, it will appear in this area, and serious equipment needs to be repaired immediately. To implement this function, the backend pushes status parameters to the frontend based on the judgment of the device monitoring sensor threshold, and the frontend puts the corresponding device icon in the position based on the status parameters. The equipment monitoring of the digital twin substation system uses artificial intelligence analysis and other technologies to analyze and judge real-time equipment data and historical data, conduct real-time diagnosis, inform the health status of the equipment, and convert manual preventive maintenance into intelligent predictive maintenance.

Hightopo 3D visualization system supports cross-platform browsing and can be browsed on any mobile terminal. Even operation and maintenance personnel who are not at the work station can monitor through mobile phones or IPads, which makes the operation and maintenance personnel in the past have to be at the main station. The limitations of control within the control room are eliminated.

Operation safety warning for personnel positioning

Tracking the location of personnel in real time, and marking them in the three-dimensional scene based on the location information returned from the background to monitor the location of the workers.

Based on the safe operating area in the system and combined with the positioning information of the workers, it is judged whether they are working in the safe area. If they exceed the safe area, a safety alarm will be issued to the workers. Combined with the preset electronic protection fence in the three-dimensional real scene, when people mistakenly enter the set dangerous area, corresponding alarms can be issued.

Transformer disassembly and assembly demonstration

Through the three-dimensional virtual simulation of transformer assembly animation, the working principle and assembly process of transformer equipment are introduced, and the composition and installation position of the main components of the transformer are visually displayed, accompanied by The text description introduces its main features, which is realistic and has a sense of technology.

This 3D visualization system independently developed by HT can be used as simulation training materials for on-site installation and maintenance of transformers, and can effectively and flexibly teach new employees the working principles of transformers.

Visualization of temperature field distribution

By real-time monitoring of the information data of the temperature and humidity sensor in the transformer, a three-dimensional heat map is used to display the temperature field of the transformer in real time, and when the mouse is hovered over the location It can display real-time temperature data at the current location, locate the heating conditions of specific components of the transformer more quickly and accurately, take timely response measures, and effectively solve or avoid uncontrollable problems.

Equipment practical operation

Using HT's innovative 3D visual modeling technology to build an interactive environment for isolating switch equipment, providing a comprehensive and practical training experience, and better It solves many difficulties and problems faced by professional large-scale and complex equipment in employee training. By controlling the operating panel, main knife gate, left floor knife, right floor knife and other components of the isolating switch operating mechanism, users can intuitively operate the equipment, understand its action principles, and truly realize three-dimensional interactive simulation demonstration training.

Real-time monitoring of sensory data

Each sensor is distributed according to the actual installation location, and the online monitoring points of primary equipment such as GIS are identified one by one. The sensors at each point are Statuses have corresponding display effects. When the mouse slides over the sensor point, its real-time status information panel is displayed. When the sensor point is clicked, its details list is entered to view the historical data and trend curve of the sensor. At the same time, you can easily switch to query historical sensor data and trend curves of other locations according to the sensor menu.

Power wiring diagram display

The substation primary equipment power wiring diagram displayed on the large screen in the main control room is a 2D configuration diagram drawn using HT technology, which can also be upgraded to a 3D configuration. Picture, even more beautiful than watching fire. The voltage and current incoming and outgoing circuits of the substation and the status of each primary equipment can be displayed in the form of 3D configuration diagrams, so that connection relationships that non-professionals cannot understand can be displayed in the Web scene through graphics, animations, etc., making it easy for the public to understand. display purpose.

Smart maintenance

The timeline displays the latest 30 self-test data. When the system starts self-test, all sensors will display the detection status in the form of animation, and the timeline will be automatically inserted. At a time point, users can check historical maintenance records and export corresponding self-inspection reports and maintenance plans.
