Where is the future of thermal power plants?

In the future intelligent power plant construction of thermal power plant, the difference from the traditional power plant operation mode is that it will involve the application of advanced technology.

In the future, all equipment in smart power plants will have self-inspection and self-evaluation functions, and their functions can be adjusted with the assistance of other equipment; Analyze and process all kinds of information extracted by big data means through artificial intelligence, optimize the production management of thermal power plants in combination with the actual situation of thermal power plants, and realize the production and operation management of thermal power plants; Based on the big data control system, the operation data of thermal power plant are counted, which makes the system gradually approach to intelligence and realize independent operation analysis.

The control and regulation system can comprehensively and intelligently supervise the whole process of the thermal power plant, and ensure the efficient operation and intelligent monitoring of the unit. Digital twin technology is used to build a high-precision three-dimensional model of thermal power plant, transmit the state and operation data of equipment to the model, and optimize the online balance and management of equipment by using real-time calculus model, thus improving the operation efficiency and maintenance efficiency of thermal power plant.

Using HT engine to simulate the construction process of booster station: foundation building → fence → transformer area → circuit breaker area → switch area → iron tower → cable, so as to realize intelligent construction control. You can choose different playback speeds, such as normal speed, 2x speed and 4x speed, to check the construction process and find unreasonable links. It can also monitor, measure, control and adjust the operating conditions of primary equipment (transformers, circuit breakers, disconnectors and other equipment directly used to generate and use electric energy).

Superimposing BIM building data into 3D scenes also supports superimposing BIM models into map scenes to realize the joint display of BIM and GIS. BIM technology is applied to the construction of booster station, covering various stages such as planning, design, construction, operation and maintenance management. Combined with BIM technology, the building structure and equipment in the booster station infrastructure system are simulated in three dimensions, which is intuitive and realistic.

Seamless integration of 2D and 3D, statistics of safe operation days, plant area, total installed capacity and real-time power of the unit by data binding of charts and charts with different styles; Daily power generation, monthly power generation and total power generation data; Production indicators such as coal feeder, coal consumption and power generation load rate; Operating efficiency of boiler units and turbo-generator units. The daily coal consumption, monthly coal consumption and total coal consumption are displayed by combining histogram and line chart, so as to understand the basic operation status of the power plant and ensure the safety, economy and power quality of the power plant.

Intelligent thermal power plants realize digital pairing of thermal power plants by obtaining three-dimensional scene data. Based on the three-dimensional technology of digital twins and the integration of new ICT technologies such as Internet of Things, artificial intelligence and big data, the safety module, environmental protection module and production module of thermal power plants are all-round digitally built to create a new generation of scientific, efficient, safe, green and healthy thermal power plants. Meteorological simulation is carried out based on meteorological data, and the three-dimensional simulation effect of different meteorological data such as rain and snow is displayed according to specific needs. You can also consult meteorological data and take countermeasures before the arrival of bad weather.

Through artificial modeling, using virtual simulation technology, according to the internal layout of the unit area of intelligent thermal power plant, 1: 1 makes a three-dimensional visual simulation interactive model, which has an unobstructed view of internal equipment and buildings and is convenient for operation and maintenance. For smart thermal power plants, simulation modeling and display are far from meeting the demand. Using GIS to locate, monitor and manage personnel, vehicles and equipment, analyzing the rationality of various monitoring points and comprehensively monitoring the production status of the factory are the key points of the intelligent transformation of the factory. In terms of safety, the factory area and fire-fighting equipment are digital twins; In terms of environmental protection, the emissions of toxic and harmful substances such as NO2, mercury and PM2.5 are analyzed, so as to guide the environmental management of thermal power plants and promote the green transformation of the plant area.

Administrators can roam the thermal power plant through the platform to check the status and location of the thermal power plant equipment, which is convenient for managers to grasp the thermal power plant as a whole.

Electric power inspectors in thermal power plants need to conduct standardized inspections on running machines, process equipment, pipelines, instruments and meters, so as to find hidden dangers, identify them professionally, handle them and report them, and make equipment failures disappear in the bud. Through the process of patrol simulation or patrol car patrol, you can stop to check the equipment information when passing through the equipment. The inspection function can select the first person according to the added multi-type inspection contents and multiple inspection paths.

The platform can realize real-time monitoring and alarm of thermal power plant equipment, respond to all kinds of abnormal situations in time, and improve the safety and command ability of thermal power plant. Specifically, the platform can achieve the following functions:

Real-time positioning and historical trajectory query: The platform can receive and manage the 2D and 3D coordinates of important personnel and equipment in real time, and the administrator can query the historical trajectory, which is convenient for the investigation and tracking of security incidents in daily management.

Visually manage the total number of people in the factory, count the personnel information of turbine, coal conveying and boiler room respectively, and quickly locate the personnel through the rapid navigation function of personnel in the three-dimensional scene. Personnel positioning helps managers to mobilize employees in various regions, strengthen overall management, and improve the intelligence level and operational efficiency of enterprises.

Based on UWB positioning base station or other positioning hardware foundation, the real-time positioning visualization function of employees in the factory can be realized in three-dimensional scene. By deploying a visual management system in the centralized control center, managers can monitor the positions of employees in the factory in real time, and view data such as employee information and action trajectory through scene interaction. Employees can carry the positioning card device with them and send out SOS information manually when they are in danger. The operation and maintenance personnel of centralized control center can respond immediately when they see the distress information in the visualization system.

Safety early warning: The platform can collect and analyze all kinds of environmental data, give early warning of possible safety risks and hidden dangers, and remind managers to deal with them in time. Safety management is the basis for the smooth and normal operation of enterprises. Using cloud computing, big data, virtual simulation, Beidou positioning and other technologies to improve the level and efficiency of safety management is the management focus of modern power plants. By displaying various icons corresponding to people or things bound to the tag on the map, the tag can be monitored in real time, and the current position of the tag can be displayed on the map for real-time control.

Electronic fence: through real-time dynamic supervision, set up areas that are physically forbidden to enter, and monitor the status of areas and equipment in real time to realize electronic fence.

In the 3D interface of thermal power plant, the position of electronic fence in the plant area is indicated in yellow, and when someone invades, a prompt box will pop up to remind the centralized control center to operate and notify the intruder to leave in time. Use 2D panel to display violation records, such as violation time, events, processing status, etc., and then strengthen management in a targeted manner. Click on the small eyes behind the electronic fence in the panel to zoom in and view the lens, or draw the electronic fence area manually as needed.

Electronic fence is an advanced perimeter protection alarm system at present, which adopts the advanced perimeter security concept of "blocking first and then alarming" and integrates "deterrence, blocking, alarm and safety", and can analyze and judge the risk of people flow. Fences are divided into permanent fences and temporary fences. Permanent fences appear in areas such as steam turbines, transformers and booster stations in thermal power plant projects. Temporary fence appears in the factory for temporary construction or

Using 2D, 3D and GIS visualization technology of Hightopo, combined with oblique photography and digital twinning technology, a three-dimensional visualization system of different units, coal conveying area, chemical water treatment area, public system area, living office area and main transformer booster station area of thermal power plant is constructed. By using ubiquitous perception, self-adaptation, intelligent integration and interaction, thermal power plants can realize intelligent management in different links such as engineering design, production scheduling, process monitoring, fault diagnosis, operation control and visual operation and maintenance. Digital twin technology is a new simulation technology using big data and artificial intelligence, which can combine the real world with the virtual world, thus realizing the optimization, monitoring and management of various production processes.
