摘要
就大型汽轮发电机模型中饱和参数对汽轮发电机组轴系扭振响应计算的影响进行了详细的研究．运用２Ｄ－ＦＥ方法计算了汽轮发电机的稳态、暂态饱和参数，提出了新的饱和修正系数；研究表明，在计算汽轮发电机组轴系扭振时。
This paper discusses the effect of saturated parameters appearing in the mathematical model of a large turbogenerator on the response calculation of shaft torsional vibration. To calculate the saturated values of steady and transient parameters,the 2D FE method is used and new correction factors proposed. The study shows that the influence of saturation must be taken into consideration when calculating the torsional vibration.
