Embodiment Construction

[0018] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and technical solutions, but the present invention is not limited to specific embodiments.

[0019] like figure 1 Shown: A single-blade installation method for wind turbines based on active feedback control.

[0020] When the wind turbine foundation 6, the transition section 5, the tower 3, the nacelle 1, and the hub 2 are installed once. The present invention proposes that the preparatory work of the installation method is the same as that of the traditional installation method.

[0021] Step 101: Tighten the hoisting cable 9, lift the hub 2 from the deck to a corresponding height.

[0022] Step 102: Turn the wheel hub 2 to make the mounting holes horizontal. The blade 11 is connected to the top of the crane 8 through the hoisting cable 9 and the hook 10; one end of the cable 12 with active tension control...

Abstract

The invention belongs to the technical field of ocean engineering and provides an active feedback control method and a device used for installing a single blade of a fan, comprising a collection system, a monitoring system, a calculation system and an execution system. The invention is suitable for installing a large sea fan. For the method of single blade installation, the total transportation time of a fan structure is shorter. After applying the method provided by the invention, the assembly process is quickened to a great extent so as to shorten the assembly time, operation time, etc. Therefore, the method is beneficial to reducing the time for installing the fan integrally, reducing the total cost of the fan, reducing the grid purchase price of wind energy, increasing the competitiveness of the wind energy and promoting the promotion and use of a clean energy.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to an active feedback control method and device for installing a single blade of a fan. Background technique [0002] For the increasing volume of offshore wind turbines, single-blade installation, as a method of wind turbine blade installation, has its outstanding features. First of all, the deck utilization rate is higher, and the installation ship can transport more wind turbine components at a time, thereby reducing the average transportation time. Secondly, this installation method requires less lifting gear, and a wider range of installation vessels can be used to achieve this installation. However, it needs to install each blade step by step, so the overall installation time is increased, and the operation is limited by the weather. The usual installation plan is to lift the blades to the height of the fan hub when weather conditions permit, and use c...
