Types of wind turbine blade transportation

1. Ordinary extendable trailer transportation

This mode of transportation generally uses ordinary extendable trailer (wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer ) to transport fan blades. The feature of this vehicle is that it can be longitudinally extended to adapt to the transportation of blades of different lengths. It can be directly transported from the manufacturer to the fan station, but it is difficult to turn due to the long turn of the vehicle.

2. Special vehicle transportation

(wind turbine blade transportation , wind turbine transportation , wind blade transportation)

This mode of transportation generally uses a special blade transport vehicle (wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer) with blade lifting-rotating-hydraulic rear wheel steering. The special vehicle can lift the blades through hydraulic control during driving, and rotate 360 ​​degrees by itself, avoiding various restrictive obstacles (mountain slopes, trees, houses, bridges, tunnels, etc.) during transportation, thereby greatly reducing blades The overall length of the transport body improves the performance of cornering.

3. Analysis and comparison

-special vehicle transportation and ordinary extendable trailer vehicle transportation

(1) The advantages of special vehicle transportation (wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer) compared with ordinary extendable trailer transportation

Transporting the blades by lifting can better avoid high mountains and cliffs, or houses and buildings, so as to realize the rapid transportation of blades. At the same time, this method can also reduce the cost of road reconstruction and house demolition, and help improve the efficiency of blade transportation and engineering benefits.

(2) The disadvantages of special vehicle transport compared to ordinary extendable trailer transport

Due to the restrictions of expressways and most grade roads, wind turbine equipment can only be transported by ordinary extendable trailer on the national public transportation network. Therefore, when mountain wind farms use special vehicles for transportation, it is necessary to choose a suitable location near the wind farm area to set up a midway transfer site. With reference to previous mountain wind power projects, if a wind farm with an installed capacity of 50MW uses special transportation, the transportation cost will need to be increased by about 3.5 million yuan. After the blade is lifted, the height increases to more than 30m, which will increase the net height requirements along the line. Compared with ordinary extendable trailer transportation, it will increase the removal of height-restricted objects (such as crossing highway cables, pipes, branches, etc.). Secondly, since the center of gravity of the vehicle rises after the blade is lifted, which is not conducive to the stability of transportation, it is necessary to place a counterweight at the front of the vehicle, and at the same time, avoid transportation in strong winds.

Main factors affecting road design

Transportation of wind turbine equipment

One of the main functions of mountain wind farm roads is to provide transportation conditions for wind turbine equipment. Therefore, the size and weight of large and heavy wind turbines transported are important factors in road design. The size and weight of the equipment are mainly related to the selected wind turbine capacity. At present, the single-unit capacity of domestic mountain wind farms is 1.5 MW, 2.0 MW and 2.5 MW, of which 2.0 MW is the most widely used. The weight control in the transportation of wind turbine equipment is mainly the wind turbine nacelle and tower. The weight of the 2.0MW wind turbine nacelle is generally about 80t, and the tower is generally transported in 3-4 sections, and the weight of the lowest section is about 40t.

The size control in wind turbine equipment is mainly blades and towers. The blade length of a 2.0MW wind turbine generally exceeds 40 m, and the width of the wind turbine tower generally exceeds 4 m. Therefore, the restrictive condition of using ordinary extendable trailer is the length of the wind turbine blades. When the road conditions in mountainous areas are poor, the wind turbine blades can be transported into special vehicles (wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer) for the second time near the approach road. At this time, the length and width of the tower tube becomes the special transportation (wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer). Ways of road design constraints.

Topographic, geological and environmental factors

Compared with the roads of wind farms in plain areas, the terrain, geological conditions and environment of mountain wind farms are more complex and diverse. Road design is more difficult to meet the requirements of wind turbine site selection and transportation 9wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer), and the amount of construction is relatively large. The access road must not only ensure convenient transportation (wind turbine blade transportation , wind turbine transportation , wind blade transportation), but also facilitate construction and transportation (wind turbine blade transportation , wind turbine transportation , wind blade transportation, wind turbine blade trailer), as well as the operation and maintenance of the wind farm after it is put into operation.

At the same time, due to the particularity of the wind turbine equipment, there will also be mutual restraints and mutual influences between it and the road layout on the site. In addition, when designing mountain wind farm roads, it is also necessary to consider ecological and environmental protection issues, pay full attention to issues such as slopes, drainage, and spoil, minimize damage to the original natural ecological environment in mountainous areas, and implement measures based on local conditions and local materials .

Construction period and investment

Compared with other traditional energy projects, mountain wind power projects have a higher unit kilowatt investment. In the investment composition of wind farms, equipment and installation projects account for the largest proportion of the total investment, which can generally reach about 70%, followed by construction projects, which are about 30%. The road investment of wind farms in plain areas accounts for a small proportion of the total investment of wind farms, generally 4%-6%. However, road investment in mountain wind farms may have a greater impact on the economic indicators of wind farms. According to the construction of Hunan Province and surrounding areas

According to statistics of wind farms, the proportion of roads is generally about 8%, and sometimes it can reach more than 10%. It can be seen that the road investment of mountain wind farms will have a greater impact on the investment and benefits of the entire wind farm. Based on this, when designing roads for mountain wind farms, key considerations should be given to the project cost and construction period. The construction period of wind power is relatively short. Taking a 50 MW wind farm as an example, it usually takes 12 to 18 months from start-up to commissioning. Mountain wind farm roads are generally only designed for one-stage construction drawings, and the survey and design time is about one month, and the construction period is relatively short. Therefore, under the premise of satisfying the use, minimizing investment and shortening the construction period are important factors to be considered in the road design of mountain wind farms.
