Digital twin 3D wind farm, offshore wind power of smart wind power

foreword

As of 2021, 127 countries around the world have made a commitment to "carbon neutrality", and low-carbon energy transition and carbon neutrality have become common global strategic goals. According to authoritative agency forecasts, by 2050, renewable energy power generation will account for more than 75% of the world's total power generation. As a typical representative of clean energy, wind power will meet 35% of electricity demand and contribute 27% of carbon emission reduction to climate goals.

Xiang Haitu is strong and strives to be the first. Compared with onshore, offshore wind power is more complex, comparable to the moon landing project. Intelligence is one of the breakthroughs in the development of offshore wind power. When the weather, power, operating status of equipment, and user-side usage can be well predicted, the utilization rate of energy and the economy of electricity consumption will have a qualitative leap.

It can quickly identify equipment abnormalities, find faulty equipment in time, quickly locate the fault point, and check the fan fault information in time by clicking on the faulty fan, so as to carry out targeted fault diagnosis and treatment, and eliminate hidden dangers in time.

Visualization of submarine cable warning statistics

Submarine cables (collection lines) are the key components of power transmission in offshore wind farms. However, due to changes in transmission power, complex subsea environment, ocean temperature changes during the day and night, seasonal temperature differences, as well as fishing, shipping and subsea activities, submarine cables are prone to problems. Accidents such as overtemperature and anchor damage occurred, resulting in great losses.

Tupu software draws and renders the distribution trend of submarine cables by connecting with the new technology of optical fiber distributed sensing. The 3D scene vividly shows the distribution and operation status of the submarine cable. Double-click the submarine cable with the left mouse button to pop up the corresponding information on the submarine cable such as temperature, current carrying capacity, strain force, etc. Combined with the visualization data of the Tupu software HT, the average parameter is displayed. The value and maximum value information is convenient for managers to infer the real state in the context of the data, so as to carry out effective supervision.

The alarm type can be freely set according to the actual situation, such as abnormal temperature, environmental damage, etc., and the abnormal status can be refreshed and displayed in real time. And through the corresponding fan to alarm and locate the abnormal submarine cable, judge whether the cable is damaged or whether the surrounding environment has changed, so as to ensure the safe operation of the submarine cable.

The electronic fence of wind power water area and the equipped early warning system provide a visual solution for the safety monitoring, early warning and maintenance of wind power water area. By docking with the shipping system, relevant information such as construction vessels, fishing vessels, and illegally invaded vessels can be obtained. Combined with the invasion time and departure time, the ship's position (longitude and latitude) can be located in real time and historical trajectories can be drawn to improve monitoring and management efficiency.

Use Tupu software to visualize the rich design elements to visually display the complex data of the electronic fence. When the ship approaches or invades the electronic fence, specific alarm information will appear in time, reminding the supervision and management personnel to quickly make the next decision, so as to play a role in Protect the role of related equipment and facilities in the electronic fence.

Video surveillance early warning visualization

Traditional video surveillance is integrated into its own video surveillance system, and the cameras are distinguished by text naming, which can easily lead to a series of problems: video dispersion, isolation, incomplete viewing angle, unclear location of hardware, etc. . The 3D visualization system built by HT supports access to the corresponding camera video image according to the actual point of the on-site camera to achieve scene restoration.

The 2D panel updates the key information of construction quality and construction safety in real time, including the number of problems found, rectification status, problems that have not been rectified, and the person in charge. It makes the supervision of wind farms more intuitive and the control more accurate.

Visualization of construction details

In order to fully complete the hoisting and pile driving construction, it is necessary not only to do a good job in the preliminary planning, but also to pay attention to the control and review of the construction technical plan. The HT engine of the Tupu software monitors and tracks the construction indicators of the fan and booster station in real time, and realizes the optimization and improvement of the hoisting and transportation scheme for many times; checking the fan foundation piling, tower hoisting, blade hoisting, waiting to be put into operation and boosting Various technical support data, such as the construction of the bottom of the station, to be put into operation, and the hoisting of the superstructure, have accumulated experience for the subsequent foundation construction and contributed to the vigorous development of the offshore wind power field in the deep water area.

Booster station information visualization

The offshore wind farm booster station consists of two parts, namely the offshore booster station and the onshore switching station. The layout of the onshore switch station is the same as that of the onshore substation. The offshore booster station operates in an unattended mode, and its management and control are monitored in real time by the onshore centralized control center through a remote method.

The HT 3D visualization booster station section of Tupu software restores the equipment in the scene by high-precision modeling. Click the corresponding icon to quickly switch and locate the internal structure of the booster station, helping to realize the unattended operation of the booster station.

Support the monitoring and measurement of the voltage and current of each grounding transformer substation, grounding transformer incoming line and submarine cable in the offshore booster station and onshore switching station, so as to analyze the abnormal operation before the equipment fails to ensure the equipment. Safe and stable operation.

Intelligent inspection

The daily maintenance of the booster station requires inspection personnel to check the equipment, which is not only inefficient, but also very dangerous. Tupu software is based on GIS indoor spatial positioning calibration, integrates the indoor positioning coordinates of the remote inspection robot, and realizes an intelligent inspection system with 1:1 scene restoration, which more visually shows the current inspection status of the robot.

Realize the display of the current state data of the patrol robot, real-time monitoring information of the patrol camera is transmitted back in real time, and displayed on the visualization platform through the HT engine. The operation and maintenance personnel and duty personnel can view the application conditions of each main transformation room through mobile phones or mobile terminals. When the high-voltage equipment is grounded, avoid personal electric shock injury, improve detection accuracy and efficiency, and reduce inspection blind spots.
