【摘要】 基于场路耦合方法,对大型汽轮发电机组轴系扭振进行了仿真与分析,考虑了动态饱和特性和转子本体涡流特性的影响。对一台600MW 汽轮发电机组在单机无限大系统中,由于突然短路故障、非同期并网以及重合闸等电力系统扰动引起的轴系扭振进行了仿真计算,结果令人满意。更多还原

【Abstract】 The transient performance of large turbogenerator sets shaft torsional vibration has been simulated and analyzed in this paper by means of the coupled field-circuit modeling. By using the finite element method,the saturation and the eddy current effects of solid rotor can be properly taken into account.The transient behavior of a 600MW turbogenerator set caused by power system disturbances,sudden short circuit,erroneous synchronization and reclosure are simulated and analyzed.更多还原
