Hoisting Solution

In the past two years, Chinese wind turbine construction has moved to the south and into other complex natural resource environments, increasing the difficulty of turbine installation. These are mountainous regions and have other features that prohibit the use of traditional hoisting machinery. To address these issues, we offer our customers a complete solution.

Three Blade Hoisting

Embedded Blade Set Base Solution

  • This solution does not require an auxiliary crane and reduces the number of cranes by two.
  • The work area is reduced from 3000 m2 to 750 m2, reducing the excavation volume and construction costs.
  • This facilitates the subsequent replacement of large parts and their on-site storage.
  • By reducing the amount of time occupied by hoisting or waiting for parts to be hoisted, the turbine installation can be completed earlier and the hoisting efficiency improved.

Elephant Leg Tooling Solution

  • This solution does not require an auxiliary crane and reduces the number of cranes by two.
  • The work area is reduced from 3000 m2 to 750 m2, reducing the excavation volume and construction costs.
  • The equipment can be moved for repeated use.

Single-blade Hoisting Process

The single-blade hoisting technology reduces the damage to vegetation and the total construction area. This extends the operating window period and reduces construction costs.

Solution for Shortening Dynamic Commissioning Grid Connection Period

  • Rapid Dehumidification System
  • Static Commissioning Trucks
  • Dynamic Commissioning Platform

In high-humidity areas, such as offshore installations and high-condensation regions, dehumidification must be completed before commissioning. Goldwind provides portable equipment that can be installed quickly for efficient dehumidification. This can reduce the dehumidification time from 48 hours to as little as 2.5 hours.

Normally, turbines are installed before the wind farm's substation has been constructed. This means the cabling of the turbines cannot be tested and, consequently, the turbines do not meet the conditions for acceptance and commissioning. Static commissioning trucks provide an effective solution to this problem.

The 20KW static commissioning truck generators have a trailer plus sound attenuated enclosure design. The diesel generator is placed in the sound attenuated enclosure, which provides sound attenuation and environmental control. This allows the turbine to start up and operate at a temperature as low as -30℃. The sound attenuated enclosure can be placed on the trailer, which can be pulled by any tractor with a tonnage above 1.5T. In addition, the equipment can be transported in harsh environments, such as the Gobi Desert.

Because wind turbine hoisting and commissioning cannot always be synchronized with power grid construction, Goldwind requires that a dynamic commissioning truck that can simulate turbine grid connection should be used after static commissioning. This ensures that turbines can promptly, efficiently, and stably operate on the grid after they are connected.

The dynamic commissioning truck is composed of a 200kW diesel generator and 300kW dummy load. When connected with a Goldwind wind power generator, it creates an independent operational system. The wind power generator and the diesel generator operate in parallel to power the resistive dummy load. The wind power generator operates at limited power, with a maximum output of 300kW. The diesel generator and load simulate a power grid. This means the wind power generator can operate as if actually connected to the grid. After powering the wind turbine, you can start the machine with a single button.
