Description

Technical Field

[0001] The present invention belongs to the technical field of offshore wind farm simulation test, and more specifically, relates to an offshore wind farm simulation test wind-generating device. Background Art

[0002] The offshore wind power floating platform test pool has the ability to simulate different sea conditions, which can provide strong support for its platform research and development and design capabilities. At the same time, based on the pool test capabilities, the key technologies of the overall design of offshore wind power floating platforms and related marine engineering platforms can be fully studied, laying a solid foundation for in-depth research and development of advanced technologies such as the design configuration, mooring system, digital twin monitoring and control of offshore floating platforms in the future. The marine engineering laboratories and port and shipping laboratories in the existing technology generally do not have the ability to simulate the environment of wind generation required by offshore wind turbines, and cannot meet the test needs of floating wind power equipment. Although there are a few wind-wave-current coupling test laboratories at home and abroad that simulate the marine environment for floating wind power foundations, some laboratories have begun to use wind and wave coupling to simulate the marine environment, but because they use a single wind turbine or a simple wind turbine composed of wind arrays, they cannot simulate the real marine wind field changes well, so they cannot meet the variable wind field and multi-sea condition test requirements required by floating platforms, and cannot provide sufficient test data support for the research and development and design of wind power platforms.

[0003] There is a technology named "a simple wind field simulation system" and the publication number is "CN104655393A" in the prior art, which belongs to the field of structural dynamic model test technology. This simulation system electrically connects the wind-generating system including the wind turbine array, the support system, the lifting system, the rectifier and the frequency modulation device and the control system including the main program control module, the wind speed calibration module and the wind spectrum parameter setting module with the wind speed time-history simulation output module. The simulation system can realize the accurate simulation output of the steady-state wind field and the pulsating wind field, and not only has sufficient stability and simulation accuracy, but also has good operability. It can carry out model tests on wind fatigue damage of marine engineering structures, dynamic model tests on wind loads of offshore wind turbine structures, and research on the aerodynamic characteristics of offshore wind turbine blades. In particular, after combining with the wave-current-earthquake simulation system to form a complex environmental load joint simulation system, it can carry out model test research on fixed and floating marine engineering structures under the joint action of environmental loads such as wind, waves, currents and earthquakes.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention
