风力发电机组传动链调谐惯量阻尼器研究

RESEARCH OF TUNED INERTIA DAMPER FOR WIND TURBINE DRIVE TRAIN

借鉴调谐质量阻尼器的力学原理,提出风力发电机组传动链调谐惯量阻尼器（tuned inertia damper,TID）。通过结构、气动、控制多学科联合仿真,研究TID对传动链扭转方向的减振、降载效果。结果表明,TID可有效降低传动链扭转方向的疲劳载荷和极限载荷,且传动链低速轴侧比高速轴侧的降载幅度更大;同时有效抑制传动链扭转方向振动,改善发电机超速状况。TID在修复因疲劳、振动导致的传动链故障和老旧机组的寿命延长方面有一定的应用价值。

A tuned inertia damper（TID）is proposed for wind turbine drive train with reference to the mechanicsprinciple of tuned mass damper.Through mechanical-aerodynamic-control multi-disciplinary co-simulation,the effect ofload and vibration reduction of TID for drive train on torsional direction is studied.The simulation results show that TIDcan effectively reduce the torsional fatigue and extreme loads of drive train,and the reduction amplitude on low speedshafts is more than high speed shafts.The torsional vibration is also damped effectively,and the situation of generatoroverspeed becomes better.TID has a a certain value of in application in terms of repairment of drive train failure due tofatigue and vibration and the lifetime extension for old wind turbines.
