摘要
为研究各参数对漂浮式风机动态响应的影响程度,寻找相应变化的规律以及设计优化的方向,对海装6.2MW漂浮式风机参数进行了一体化仿真。结合规范要求、设计经验和环境条件特点,针对各影响因素的研究表明:仿真时间和种子数量对整个装备动态响应影响明显,极端发电和极端空转工况采用1 h仿真和3个种子数量结果会更准确。正常发电工况风机载荷主要由风载荷控制,极端发电和空转工况则同时受风浪流控制。发电工况风浪夹角主要对运动响应和锚链张力影响较大,空转工况则对整体动态响应均有较大影响。极端偏航误差角主要影响机组载荷,因此在空转工况保证机组能实时对风是十分必要的。
Integrated simulation of the 6.2 MW offshore floating wind turbine is carried out to determine the influences of various parameters on its dynamic response and find the variation properties and the optimization directions.Considering the specification requirements,design experience and environmental conditions,the simulation results show that the simulation time and the seed number have significant impacts on the dynamic response of the whole equipment.Under the extreme power generation condition and the extreme idling condition,the simulation results with 1h simulation time and 3 seeds are more accurate.Under the normal power generation condition,the turbine is mainly controlled by the wind load.While under the extreme power generation condition and the extreme idling condition,it is controlled concurrently by the wind,wave and current loads.The wind-wave angle has great influences on the motion response and the anchor chain tension under the power generation condition,while it poses great influences on the overall dynamic response under the idling condition.The extreme yaw error angle mainly affects the turbine loads.Thus,it is of great necessity to ensure the unit be directed at the wind direction in real time under the idling condition.
