摘　　要：双馈风力发电机组在进行低电压穿越时,电网电压突变以及变流器控制策略的突然变化,可能导致风力发电机转轴等部件机械寿命的缩短,甚至被严重损坏。对双馈风力发电机转轴进行静强度及疲劳校核前,需要进行电机转轴的三维建模,涉及模型网格的划分、初步结果分析及结果优化等重要内容。该建模是电机转轴静强度分析和疲劳校核的重要基础。When the doubly fed induction generator(DFIG)carries out low voltage crossing,the sudden change of power grid voltage and the sudden change of converter control strategy may lead to the shortening of the mechanical life of mechanical components such as wind turbine shafts,or serious damage.Before the static strength and fatigue verification of the shaft of DFIG,it is necessary to carry out three-dimensional modeling of the motor shaft,involving the division of the model mesh,preliminary result analysis and result optimization.The modeling is an important basis for static strength analysis and fatigue verification of motor shafts.
