摘要
以适合于分析汽轮发电机组机电振荡问题的轴－机－网系统全时域数字仿真计算程序为手段，针对华中电网汉川电厂的３００ＭＷ汽轮发电机组，研究了大扰动时序（包括故障时刻，故障切除时刻，单相、三相自动重合闸时刻）对机组轴系扭振的影响；分析了这些因素产生影响的根本原因；总结了其中的变化规律。
In this paper,a digital computer program is presented to analyze the oscillationbetween the electrical and mechanical system in time domain.The effects of large disturbancetime sequence(including fault time,fault clearing time,single and three phase reclosing time)onthe shaft system torsional vibration are investigated for the 300 MW steam turbo- generator unitin the Hanchuan power plant.The physical rcasons are analysized,and the properties of the shaftsystem torsional vibration under various fault conditions are concluded.
