The construction and operation and maintenance of offshore wind farms are greatly affected by marine climate conditions. Offshore wind farms have problems such as poor accessibility, high safety risks of marine traffic, and short effective operation time. It is the key to the safe and efficient operation of wind farms to make reasonable use of the effective window period to complete the operation and maintenance tasks, ensure the safety of wind turbine equipment and reduce unplanned outages.
Through the construction of the platform, the effectiveness of online monitoring and forecasting and early warning can be utilized to reduce unplanned outages of offshore wind power, increase the power generation of offshore wind turbines, and ensure the safe and stable operation of equipment.

At the same time, roaming from the booster station to the air roaming view through the perspective of the drone, intuitively showing the grandeur of the wind farm, bringing a unique and shocking look and feel.
production monitoring
Due to the unstable wind volume of wind turbines, and their ability to support the operation of the power system is not as good as other power generation fields, the monitoring data of wind power base facilities needs to be more time-sensitive. The key production data of wind farms are concentrated on the left and right sides of the interface, providing managers with intuitive data display and timely control.
Tupu software's 3D visualization technology adopts B/S architecture, and the page adapts to multiple resolutions. Users can access the 3D visualization system anytime and anywhere through a PC, PAD or smart phone, as long as they open a browser, and realize remote monitoring and control.

The panel shows the power generation of the day, the month and the cumulative power generation; the daily power generation ranking of all wind turbines is displayed in the form of a bar graph.
Energy conservation
Through the visualization system of Tupu software, the emission data of nitrogen oxides in wind power bases can be remotely monitored and counted, and the optimal solution for energy saving and emission reduction can be achieved following the law.
Popular science tips:
The report of the United Nations Economic Commission for Europe on "Full Life Cycle Power Generation Options" pointed out that during the whole life cycle of a power station, wind power without carbon capture technology emits 10 grams of carbon dioxide per kWh.
number of unit status
Using the diversified chart forms of Tupu software, it can display the number of wind turbines that are normally generating power, generating power with disease, standby, self-limited power, planned shutdown, and communication interruption, so as to facilitate real-time acquisition of the operating status of the entire wind turbine.
Booster station monitoring
Through on-site view photos, satellite images, CAD drawings and other materials, Hightopo can quickly restore the actual wind power base online, and realize digital twins through data access. The streamer effect is used to simulate the process of current gathering of different wind turbine collector lines to the booster station, more intuitively display the wind power generation process, and bring better immersive experience, viewing experience, and interactive experience.
The wind farm booster station refers to the facility that boosts the output voltage of the wind turbine to a higher level voltage and sends it out. Since wind turbines are mostly asynchronous generators, wind farms will absorb reactive power while generating active power, and most wind turbines cannot perform continuous and effective active and reactive power regulation. If corresponding control measures are not taken, it may affect the power grid. Power and voltage stability will be affected, or the network loss of the power grid will be increased.
In order to solve the voltage stability problem of the output system brought about by the grid-connected operation of large-scale wind farms, the reactive power compensation method in the wind farm collection booster station generally adopts the combined operation of static var generator (SVG) and shunt capacitor banks.

realize value
The ability of new energy to provide long-term stable power guarantee is poor, and affected by the rolling update of meteorological data, the power forecast of new energy still deviates from the actual result. The large-scale access to new energy has exhausted the existing conventional power supply and pump-storage regulation capabilities, and the balance model of "source follows load" is unsustainable. The system's balance regulation capability needs to be improved urgently, and it is necessary to accelerate the construction of "source-network-load-storage" interaction new power system.
