基于工程实践的汽轮发电机组不稳定振动的研究

Based on the Engineering Practice of Instability Vibration Research for the Steam Turbine Unit

统计分析了十年来30台次的大型汽轮发电机组发生的不稳定振动故障的实例,对发生不稳定振动故障来源阶段及形式进行了统计分析,同时统计分析了引起机组不稳定振动故障的主要原因占比,结合现场实际案例阐述了机组发生不稳定振动故障所表现的特征及处理措施,为大型汽轮发电机组的安全运行提供了技术参考与依据。

Thirty sets of large turbine generator unit instability vibration were listed for ten years, and the unstable vibration fault source phase and form has carried on the statistical analysis, and statistical analysis of the generating units of the main causes of unstable vibration fault ratio, and expounded with actual cases of unstable vibration fault occurring characteristics and treatment measures, for the safe operation of large turbine generator set provided technological reference and basis.
