Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 As shown, an experimental method of a floating offshore wind turbine hybrid model experimental device placed in a wind tunnel includes the following steps:

[0023] Step 1. The production of the experimental model. In order to ensure that the experimental model and the entity strictly meet the geometric similarity conditions, it is necessary to follow a unified experimental model scale ratio during the production and simulation of the experimental model. When the experimental model is tested in a marine engineering pool , it is necessary to convert these scale parameters and external design dimensions, and describe them by formula (1),

[0024]

[0025] where h m is the water depth of the experimental model during the test, H m is the wave height of the experimental model during the test, λ m is the wavelength of the experimental model during ...

Abstract

The invention belongs to the technical field of ocean engineering, and relates to a floating offshore wind turbine generator hybrid model experimental device placed in a wind tunnel and a method. Theexperimental method comprises the following steps: (1) production of an experimental model, (2) connection of a monitoring unit and a motion control computer, (3) control command transmission, (4) constant wind simulation, (5) motion state feedback. The experimental device includes a manipulation system portion, an experimental model portion, and an air bellow. Compared with the prior art, the experimental model part of the device can be placed in a wind tunnel for testing, without relying on a wave tank, and can better reveal influence of hydrodynamics on aerodynamic performance of a fan.

Description

technical field [0001] The invention relates to a hybrid model experiment device and method of a floating offshore wind turbine placed in a wind tunnel, and belongs to the technical field of marine engineering. Background technique [0002] Offshore wind energy, as a clean and renewable energy, has attracted more and more attention from all over the world. When the seawater depth exceeds 50m, the floating offshore wind turbine (FOWT) will have better economic feasibility. As an emerging frontier field, FOWT has extremely complex coupled wind and wave environment physical characteristics and lack of actual construction engineering experience. Relevant numerical research needs to rely more on physical model tests for verification. How to truly reproduce the offshore environment and improve the FOWT model The accuracy of experimental research is a common concern of scholars at home and abroad. The current fan model based on the strict Froude number similarity criterion cannot ...
