Smart wind power: digital twin 3D wind turbine intelligent equipment operation and maintenance

foreword

On June 1, the Fujian Provincial People's Government issued a notice on the "Fujian Province's 14th Five-Year Plan for Energy Development Special Plan". Planning requirements, increase the scale of wind power construction. Since the promulgation of the "30.60" dual carbon goal, all sectors of society have pressed the "accelerator" button for carbon reduction, and zero carbon has become a hot word in the industry. With the advancement of intelligent technology and the accelerated pace of wind power industrialization, my country's wind power development has an industrial foundation for large-scale development and application. When digital technologies such as big data and artificial intelligence cross the wind power industry, smart wind turbines emerge as the times require.

Relying on the self-developed HT for Web product, Tupu Software has built a digital twin system for the management of large-scale wind turbines, involving three monitoring modules: online monitoring, fire monitoring and production monitoring. By providing solutions for the visual management of the entire life cycle of wind turbines, it helps customers reduce costs and improve management efficiency. Users can choose to view the corresponding monitoring content data in 360 degrees through different monitoring modules, and zoom in, zoom out, pan and other operations to view the scene effect, data indicators, equipment status, etc.

Production monitoring

In the field of new energy wind power, the wind turbine drives the blades to rotate through wind energy, and the generated mechanical energy is transmitted to the generator, and finally converted into electrical energy. It has the characteristics of cleanliness, good environmental benefits, renewable and inexhaustible, and can gradually achieve zero emissions. Therefore, the monitoring of production efficiency is particularly important.

Tupu software uses the self-developed HT for Web product to build a three-dimensional model of the internal power generation process of the fan system. 1:1 restore the external structure and main components of the wind turbine, and restore the key data of each component of the wind turbine by connecting the real-time data of the physical sensor, build a comprehensive production perception of the wind farm unit, and realize the visualization of the environment, electricity, and performance.

Wind turbine power generation visualization

The 2D panel displays the relevant indicators of wind turbine power generation: power generation, wind speed-power, and main power generation operation accuracy indicators. And through the graph to show the trend of power generation with wind speed, the staff can clearly and clearly grasp the power generation law, make adjustments in time, and avoid the loss of power generation due to improper arrangement of operation and maintenance activities.

Main power generation operating parameters

The monthly power generation statistics table is one of the important contents of the operation work, and its authenticity is directly linked to reliability and economic benefits. Use the rich charts and animation effects of the Tupu software HT to interpret the data of power generation operating parameters in different dimensions.

Fan form switching

The main form of the fan is divided into three types: solid model, wireframe model and explosion effect. By clicking the button below, you can switch to the form corresponding to the button. Click on the explosion effect to intuitively understand the appearance and structure of the main components in the cabin.

The power generation process is depicted in wireframe mode, and users can click on the fan components to view the corresponding detailed information, which is displayed on the 2D panel. Including real-time display of pitch shaft, nacelle, main shaft, generator and gearbox parameters, monitoring the temperature of fan components, and giving early warning instructions.

The 2D panel on the left displays the basic information of the fan, including the fan name, power, wind speed, wind direction, and ambient temperature.

Online Monitoring

Condition monitoring and fault judgment during the operation of wind turbines are important factors to ensure the safe operation of wind turbines and obtain long-term stable income. Therefore, in addition to online monitoring of equipment in the engine room such as main bearings, gearboxes, and generators, important components such as blades and bolts should also be monitored. According to different application scenarios and characteristics, Tupu software displays the fan operating parameters in real time. Including blade monitoring, bolt monitoring, corrosion monitoring, tower monitoring and submarine cable monitoring. Real-time display and judgment of the operating status of the fan, prompt alarm information in a timely manner, so that users can make decisions in the first time.

Leaf monitoring

The blade is the "feel" of the wind turbine to feel the wind energy. The intelligent monitoring system built by Tupu software can feedback the running status of the blades in real time through the images and results collected by aerial oblique photography. By clicking on the tip, upper middle, lower middle, and root of a certain blade in the 3D fan model with a specific number, the user can view the defect pictures of a total of 48 parts on the windward side, the cover, the leading edge, and the trailing edge. It is convenient for users to quickly check the health status of blades, and eliminate risks in the "cradle".

Bolt monitoring

The online monitoring module of tower bolts and blade root bolts can monitor the tightening status, back-rotation loosening, and bolt pre-tightening force deviation of the connecting bolts at key positions of the fan in real time, effectively ensuring the safe and stable operation of the unit.

Corrosion Monitoring

The traditional corrosion monitoring is mainly to install and remove coupons for inspection during shutdown and maintenance. It needs to destroy the structure of the material, the test time is long, and the result is often the sum of the corrosion generated in the entire test cycle, which is not suitable for on-site use. Tupu software displays parameters such as corrosion current, potential, and corrosion amount at the installation point of the equipment by docking corrosion sensors and environmental multi-factor sensors, so as to effectively characterize environmental corrosion and provide the cause of corrosion for offshore wind power and the formulation of corresponding anti-corrosion measures. scientific basis.

Tower monitoring

The HT engine of Tupu software can monitor the tilt state of the tower as a whole, monitor the angle of the tower base, and give early warning by connecting multi-level deployment sensors to ensure the tower maintains a healthy and stable operation state and reduce the occurrence of safety accidents.

Submarine cable monitoring

The offshore wind turbine and submarine cable monitoring module can obtain sensor data through the interface, and monitor the temperature and voltage of the submarine cable in real time. Judging whether the submarine cable hub circuit is abnormal can play a timely warning role for submarine cable failures.

fire monitoring

The fire monitoring module mainly realizes all-round and in-depth acquisition and real-time data display of temperature, current, and engine room equipment through various sensors connected to various positions in the wind turbine.

Each sensor is distributed in the cabin according to the actual installation position, and the sensor status of each point has a corresponding display effect. Click the sensor point with the left mouse button, and the real-time status information panel will pop up. Includes smoke detectors, gas start/stop buttons, hot aerosol fire extinguishers, etc. Through multi-dimensional data monitoring, accurate and effective data input is provided for the management and control of smart fans. The 2D panel on the right contains the basic information list of fan temperature, current and cabin equipment status, and monitors the health status of the fan in real time.

Realize the diagnosis and prediction of the fan operation process, users can make reasonable scheduling and decision-making according to the health status of the fan, reduce the maintenance cost of the fan, improve the safety of the fan, and truly realize intelligent management.

Tupu software has also developed a 3D sci-fi wind turbine based on HTML5 WebGL, so that the various functions of the wind turbine can be displayed to everyone at close range. In this scene, we used the technical wireframe style to show the internal structure of the wind turbine, which is more shocking and cool in the senses than most of the real scene construction. While showing the internal structure of the wind turbine, the environmental parameters around the wind turbine, offshore wind direction and wind speed information, data monitoring of the wind turbine itself, and power generation parameters are also displayed on both sides.

We have also designed a cool one-stop fan data visualization display platform, free to deploy real-time data, and have a panoramic view of the project's operating status and health status.

After the world's first zero-carbon terminal system is connected to the grid for power generation, the production equipment is 100% self-sufficient in green power supply through the "wind-solar-load-storage integration" system, with zero carbon emissions throughout the process. It marks a new step in the construction of a green port in Tianjin Port, and leads the green and low-carbon development of the industry with a new model.
