摘要
近海风电结构的发展正面临“降本”、“增效”两方面问题的考验,结构振动控制技术是其突破难题的有效手段之一。然而,由于风电塔上部的风轮-机舱组件(rotor-nacelle assembly,RNA)在运行状态的非线性控制策略,给风电结构的振动控制带来了新的挑战。针对国内外近海风电结构振动控制的相关研究进行了搜集、整理与归纳,结合近海风电结构体系的动力特点分析了不同类型阻尼器的减振原理、研究方法、适用场景与性能优劣。结果表明:风电结构的振动控制将从传统高耸结构的控制理论出发,结合风机的变速-变桨时变特性,提出更加高效、有针对性的减振技术。
The development of offshore wind turbine structures faces the test of both“cost reduction”and“efficiency enhancement”,and the structural vibration control technology is one of the effective means to break through the problem.However,the non-linear control strategy of the rotor-nacelle assembly(RNA)of the upper part of the wind turbine tower in operation brings new challenges to the vibration control of wind turbine structures.This paper collects,organizes and summarizes the relevant researches on the vibration control of offshore wind turbine structures at home and abroad,and analyzes the vibration damping principles,research methods,applicable scenarios and performance advantages and disadvantages of different types of dampers in combination with the dynamic characteristics of offshore wind power structural systems.The results show that the vibration control of wind turbine structures will be based on the control theory of traditional towering structures,combined with the variable speed-pitch time-varying characteristics of wind turbines,to propose more efficient and targeted vibration reduction techniques.
