| Abstract: | 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. |
