About the Research Work of Turbogenerator Torsional Oscillations

本文对在我国开展汽轮发电机组轴系扭振的研究工作就以下几个方面提出若干建议: 关于扭振研究工作的重点, 关于数学模型的建立和数据采集, 关于扭振暂态的计算分析, 关于扭振的监测和分析装置, 关于减少扭振危害的对策。认为围绕电力系统中急剧扰动引起的扭振开展研究刻不容缓.

In this paper, proposals in the following areas of turbogenerator torsional oscillation (TTO) researches in China are presented: * Concerning the focal points of TTO studies; * Concerning the modelling and data acquisition of TTO; * Concerning the computation and analysis of TTO transients; * Concerning the monitoring and analyzing devices of TTO; * Concerning the countermeasures against TTO. It is concluded that researches centered on torsional oscillations caused by system disturbances and swithching events should begin as early as possible.
