对某风电场2.0 MW风电机组120 m高单管式风力发电钢塔和钢-混凝土组合式风力发电塔的振动进行长期监测,分别采用峰值拾取法(PP)和随机子空间法(SSI)对塔架的模态参数进行识别和分析,并与数值分析结果进行对比。结果表明:两座塔架的振动主要以前三阶模态为主,高阶模态的影响不可忽略。相较于钢-混凝土组合塔架,纯钢塔架受塔顶叶轮转动的影响更大,更易发生共振。模态阻尼中气动阻尼占比较大,其与环境风速和桨距角关系密切,与风速呈非线性关系,并且在桨叶变桨时变化明显。对比实测识别和数值分析结果发现,两座塔架的模态频率以及混塔的振型数值分析结果与实测结果比较吻合,钢塔的振型数值分析结果与实测结果存在差异,在运维养护时应重点关注。
