Wind power development has two directions. One is the wind field. In this regard, the country has always supported the wind farm pool, and the technical difficulties of wind power grid can also be overcome. There have been difficulties on the Internet. Let ’s explain to the landlord The electric energy as a secondary energy source. It cannot be stored. If you use how much electricity, you must send it as much as possible. Adjustment is called peak adjustment. The thermal power plant has a strong peak -regulating ability, but the peak adjustment capacity of the wind field is very poor, there is wind power generation, no wind does not generate electricity, strong wind and high power power generation, weak wind and low power power generation, the power depends only on the wind cannot follow the user's load For this adjustment, the wind power must be packed merged with the electricity plant into the grid to achieve a peak of wind power. However, the cost of peak -adjusting thermal power is huge. The cost of turning on a crew of a thermal power plant is 200W, and the cost and power of the production unit of thermal power plant production unit are inversely proportional. The greater the power generation power of the thermal power plant, the lower the cost. When wind power and thermal power are packed, thermal power must be reduced, and the power generation cost of thermal power plant naturally increases. In the context of high coal prices, the cost of thermal power generation has intensified, and the thermal power plant that has been running at a loss of money naturally does not want to connect to the wind power, so wind power connection has always been a problem. Itmies to another development direction: equipment manufacturing, there are many manufacturing companies with wind power equipment in China, such as Jinfeng, Casino, etc., some of the wind turbines they produce are sold to the wind farm, and the other part is exported abroad. Due to the excessive heat production capacity of wind power equipment manufacturing and the continuity of the financial crisis, the export volume of wind motors decreased sharply, which led to the outbreak of the "cancellation door" of Huarui Group last month. It can be said that the situation of wind power equipment manufacturing is not optimistic. Essence The in the future, with the exhaustion of energy, the reform of the system and the survival of the fittest in the equipment manufacturing industry, the wind power will still have a good development, but this development will take a long way, but in the era of the energy of the century New energy will go further.

Show a digital twin fan running diagram to help everyone understand the principle of fan power generation. The wind power generator converts wind energy to mechanical energy. The working principle is relatively simple. The wind wheel rotates under the action of wind. It transforms the kinetic energy of the wind into the mechanical energy of the wind wheel shaft.
The mechanical equipment includes: cabin, rotor blades, shaft hearts, low -speed shafts, gearboxes, generators, electronic controllers, hydraulic systems, cooling components, tower, wind speed meter, air vane, etc. On June 1st, the Fujian Provincial People's Government issued a notice on the "Fourteenth Five -Year Plan for the" Fourteenth Five -Year Plan "Energy Development of Fujian Province". Planning requirements increase the scale of wind power construction. Since the "30 · 60" dual carbon target was promulgated, all sectors of society have pressed the carbon reduction "acceleration key", and zero carbon has become a hot word in the industry. With the advancement of intelligent technology and the pace of wind power industrialization, my country's wind power development has a large -scale development and application industrial foundation. When the digital technology such as big data, artificial intelligence, and other digital technology cross -border wind power industries, smart fans came into being. In the field of new energy wind power, wind turbine drives the blade rotation through wind energy, and the mechanical energy generated by the wind power is passed to the generator and eventually transformed into electrical energy. It has the characteristics of cleaning, good environmental benefits, renewable, and never exhausted, and can gradually achieve zero emissions. Therefore, monitoring of production efficiency is particularly important. The state monitoring and fault judgment in the operation of fan operation is an important factor in ensuring the safe operation of the wind motor and obtaining long -term stable income. Therefore, the three -dimensional model of the internal power generation process of the fan system, 1: 1 restore the external structure and main components of the fan, and use the real -time data of the physical sensor to restore the key data of each component of the fan, build a comprehensive wind farm unit comprehensive Production perception to achieve visualization of environment, power and performance. The overall construction of HT developed by the use of map fluttering software. The power generation process is described by wire frame mode. Click the fan component to view the corresponding details and display it on the 2D panel. Including the real -time display of the paddle shaft, cabin, main shaft, generator and gear box parameters, monitor the temperature of the fan component, and give early warning instructions. This 2D panel display fan basic information, including fan names, power, wind speed, wind direction, and ambient temperature. Therefore, in addition to the online monitoring of the in -cabin equipment such as the main shaft, gearbox, generator, etc., it also should also be monitored by important components such as blades and bolts. Tap Software is displayed in real time for the fans for different application scenarios and characteristics. Including leaf monitoring, bolt monitoring, corrosion monitoring, tower monitoring, and seaside monitoring. Display the operating conditions of the fan in real time, and prompt alert information in a timely manner to facilitate users to make decisions in the first time. Monitoring system tasks: Control wind power generator grid and network, the operation status of the monitoring unit, the condition and meteorological conditions of the power grid, the protection of abnormal operating conditions, and record the operation data such as wind speed, power, power generation and other units. 2D panel display fan-related indicators: Power generation, wind speed-power, and accurate indicators of major power generation operations. And through the curve chart, the power generation power changes with the wind speed, and the staff can clearly and clearly grasp the laws of power generation and make adjustments in a timely manner to avoid losses caused by improperly arranged by operation and maintenance activities. The diagnosis and prediction of the operation of the fan. Users can make reasonable scheduling and decision -making according to the health of the fan, reduce the cost of fan maintenance, improve the security of the fan, and truly realize intelligent management. starting from the wind, not just the wind. Integrate visualization, big data, GIS technology, break the phenomenon of data islands, tap the value behind data, help discover the laws and characteristics of them, and create a reliable, responsible and sustainable future new energy world. Commonly realize the "sustainable, better" zero carbon future.

The wind power generator converts wind energy to mechanical energy. The working principle is relatively simple. The wind wheel rotates under the action of wind. It transforms the kinetic energy of the wind into the mechanical energy of the wind wheel shaft.
The mechanical equipment includes: cabin, rotor blades, shaft hearts, low -speed shafts, gearboxes, generators, electronic controllers, hydraulic systems, cooling components, tower, wind speed meter, air vane, etc.
On June 1st, the Fujian Provincial People's Government issued a notice on the "Fourteenth Five -Year Plan for the" Fourteenth Five -Year Plan "Energy Development of Fujian Province". Planning requirements increase the scale of wind power construction. Since the "30 · 60" dual carbon target was promulgated, all sectors of society have pressed the carbon reduction "acceleration key", and zero carbon has become a hot word in the industry. With the advancement of intelligent technology and the pace of wind power industrialization, my country's wind power development has a large -scale development and application industrial foundation. When the digital technology such as big data, artificial intelligence, and other digital technology cross -border wind power industries, smart fans came into being.
In the field of new energy wind power, wind turbine drives the blade rotation through wind energy, and the mechanical energy generated by the wind power is passed to the generator and eventually transformed into electrical energy. It has the characteristics of cleaning, good environmental benefits, renewable, and never exhausted, and can gradually achieve zero emissions. Therefore, monitoring of production efficiency is particularly important.
The state monitoring and fault judgment in the operation of fan operation is an important factor in ensuring the safe operation of the wind motor and obtaining long -term stable income.
Therefore, the three -dimensional model of the internal power generation process of the fan system, 1: 1 restore the external structure and main components of the fan, and use the real -time data of the physical sensor to restore the key data of each component of the fan, build a comprehensive wind farm unit comprehensive Production perception to achieve visualization of environment, power and performance. The overall construction of HT developed by the use of map fluttering software.
The power generation process is described by wire frame mode. Click the fan component to view the corresponding details and display it on the 2D panel. Including the real -time display of the paddle shaft, cabin, main shaft, generator and gear box parameters, monitor the temperature of the fan component, and give early warning instructions.
This 2D panel display fan basic information, including fan names, power, wind speed, wind direction, and ambient temperature.
Therefore, in addition to the online monitoring of the in -cabin equipment such as the main shaft, gearbox, generator, etc., it also should also be monitored by important components such as blades and bolts. Tap Software is displayed in real time for the fans for different application scenarios and characteristics. Including leaf monitoring, bolt monitoring, corrosion monitoring, tower monitoring, and seaside monitoring. Display the operating conditions of the fan in real time, and prompt alert information in a timely manner to facilitate users to make decisions in the first time.
Monitoring system tasks: Control wind power generator grid and network, the operation status of the monitoring unit, the condition and meteorological conditions of the power grid, the protection of abnormal operating conditions, and record the operation data such as wind speed, power, power generation and other units.
2D panel display fan-related indicators: Power generation, wind speed-power, and accurate indicators of major power generation operations. And through the curve chart, the power generation power changes with the wind speed, and the staff can clearly and clearly grasp the laws of power generation and make adjustments in a timely manner to avoid losses caused by improperly arranged by operation and maintenance activities.
The diagnosis and prediction of the operation of the fan. Users can make reasonable scheduling and decision -making according to the health of the fan, reduce the cost of fan maintenance, improve the security of the fan, and truly realize intelligent management.
starting from the wind, not just the wind. Integrate visualization, big data, GIS technology, break the phenomenon of data islands, tap the value behind data, help discover the laws and characteristics of them, and create a reliable, responsible and sustainable future new energy world. Commonly realize the "sustainable, better" zero carbon future.
