大型风力发电机组地震载荷计算方法研究

Study on Seismic Load Calculation Method for Large Scale Wind Turbine

随着国家大规模开发风力发电,风力发电机组安全性逐渐受到重视。近年来全国地震时有发生,由于地震很难预测,并且具有很强的破坏性,风力发电机组在地震情况下的安全性必须在设计中考虑。文章介绍了风力发电机组地震设计标准,分析了地震载荷计算原理。最后根据2 MW陆上双馈风力发电机组,分析了地震载荷对风力发电机组各个部件设计的影响,为风力发电机组地震载荷计算提供了参考经验。

Along with the large-scale development of wind power, the safety of wind turbine has been paid more and more attention. The earthquake has occurred occasionally in recent years. Due to the unpredictability and strong destructiveness, the safety of wind turbine in earthquake must be considered in design. The seismic design criterias of wind turbine are introduced and the principles of seismic load calculation are analyzed in this paper. Eventually, according to the onshore 2 MW double-fed wind turbine, the effects of seismic load on the design of wind turbine components are analyzed, which provide reference experience for wind turbine seismic load calculation.
