May I ask how big a wind farm requires a wind measuring tower?

According to the "Interim Measures for the Management of Wind Power Development and Construction", Chapter 3, Article 13, wind power project applications must submit wind resource assessment results, so wind resource assessment results are required regardless of the size of the wind farm. If you need to build a wind measuring tower, we recommend Eternal Communication.

The requirements for the location of the wind measurement tower are as follows:

1. Avoid the influence of terrain;

2. There should be no tall buildings, trees, etc. near the location of the wind measurement tower. For obstacles, the distance from a single obstacle should be greater than 3 times the height of the obstacle, and the distance from rows of obstacles should be maintained at more than 10 times the maximum height of the obstacle;

3. The location of the wind measurement tower should be at Within 5km of the wind farm and not affected by the wake of the wind farm, the location should be upwind of the main wind direction of the wind farm;

4. The number of wind measurement towers depends on the complexity of the terrain, climate characteristics and installed capacity of the farm. Certainly. For wind fields with relatively flat terrain, you can choose to install a wind measuring tower. For wind fields with complex terrain, two or more wind measuring towers should be installed.

If you want to know more about the wind measurement tower, it is recommended to choose Eternal Communications. The communication tower body of Yongheng Communication Company generally adopts four-column angle steel or steel pipe structure, and is equipped with lightning rods, working platforms and ladders. The steel of the tower body is made of Q235 steel. The material origin is Baosteel, Shougang, Handan Iron and Steel, Tangshan Iron and Steel, etc. Its technical conditions should comply with the provisions of the GB:700-88 standard; at the same time, the steel components of the tower body are hot-dip galvanized for anti-corrosion treatment, guaranteed for 50 years No rust; quality you can trust.

What does the wind farm anemometer tower data include?

A tower-shaped structure used to observe and record the movement of near-surface airflow. In the past, they were mostly built by meteorological and environmental protection departments for meteorological observation and atmospheric environment monitoring.

In recent years, with the widespread global attention to wind energy resources and the rapid development of the wind power industry, governments, enterprises or wind power developers have begun to invest in the construction of wind measurement towers to prepare for future investment and construction of wind farms. Get first-hand wind energy information.

Anemometer towers are erected in wind farm sites. They are mostly quilted structures and cylindrical structures. They adopt steel strand cable-stayed reinforcement methods and are generally 10-150 meters in height. Anemometers, wind vanes, temperature, air pressure and other monitoring equipment are installed at different heights of the tower. The wind conditions at the site can be observed around the clock, and the measurement data is recorded and stored in a data logger installed on the tower.

The main functions of the wind tower: environmental monitoring, wind, air pressure, humidity and other resource data collection. Provide support for the installation of corresponding instruments and equipment.

Applicable units: Preliminary planning of power plants, island wind measurement, meteorological data collection, environmental monitoring and other departments.

The difference between weather stations and anemometer towers

Wind farm anemometer tower data includes; time, wind speed, wind direction, temperature, pressure, etc. For more detailed information, it is recommended to consult Yongheng Communication. The company considers all users and pursues the principle of "pragmatism, refinement, and sincerity."Then, provide users with excellent products and excellent services.

Anemometer tower data;

1. 5min average wind speed, sampled once per second, automatically calculate and record the average wind speed every 5min, m/s.

2. Hourly average wind speed: Obtain the hourly average wind speed through the 5-minute average wind speed value, m/s.

3. Maximum wind speed: the maximum value of wind speed sampled every 3 seconds, m/s.

4. Wind direction sampling: The wind direction of the wind speed is collected synchronously with the wind speed.

5. The wind direction recorded in the wind direction area is the instantaneous sampling value of a certain wind speed in the area. When the wind direction area is divided into 16 equal parts, each fan-shaped area contains 22.5° and how many degrees can be used to express the wind direction.

6. Temperature: Take samples every 5 minutes and record the ambient temperature of the collection site, ℃.

7. Relative humidity: Take samples every 5 minutes and record the environmental humidity at the collection site, RH%.

8. Air pressure: Take samples every 5 minutes and record the air pressure at the collection site, hPa. Click to get the preferential policy

If you want to know more about wind tower data, it is recommended to choose Eternal Communication. During the design conversion, in order to ensure that the technical drawings input for processing are accurate, Yongheng Communication Company will first check the technical conditions and processing requirements provided by the user. The computer is connected to the terminal of CNC equipment such as cutting and bending to ensure the reliability and accuracy of the processed products. Establish a firm and sober quality concept, pay attention to every detail in the product quality chain, strictly require all products to meet standards, and strive to reduce defects and deficiencies to zero.

What is the height of the tallest wind tower in China?

1. Different measurement methods. Weather stations generally perform fixed-point measurements, while wind towers perform mobile measurements.

2. Different application fields. Data from weather stations are mostly used for weather forecasting, while data from anemometer towers are mostly used for wind power generation forecasting in specific places such as wind farms.

3. The measuring instruments are different. Weather stations generally use wind vanes, anemometers, etc. to measure wind speed, while anemometer towers generally use anemometers and other instruments to measure wind speed.

The Huastron prestressed frame steel tube wind power tower invested by Qingdao Jinjiaozhou Asset Management Co., Ltd. is 170 meters high.

The form now designed by "Huastron" is a frame type. The four corners have stronger bearing capacity through the lower tower body, which solves the problem of welding fatigue and can effectively avoid resonance. , this technology with more than 20 national and international patents can significantly increase the height of the tower, better utilize wind resources, and increase the effective hours of power generation.

The production process of wind power towersGenerally as follows:

CNC cutting machine cutting, thick plates need to be beveled , after the plate is formed by the plate rolling machine, spot welding, positioning, and after confirmation, the inner and outer longitudinal seams are welded.After the joint and roundness inspection, if there is any problem, perform a secondary rounding. After the single-section cylinder is welded, a hydraulic group is used to spot-weld the roller frame and then weld the inner and outer circumferential seams.

After straightness and other tolerance inspections, after flange welding, weld non-destructive testing and flatness inspection, sand blasting and painting, after internal parts installation and finished product inspection are completed, they are transported to the installation site.
