摘要 轴系扭振应力分析系统(TSA)对于机组的扭振事故分析、经济运行及安全保证是十分必要的。本文对TSA涉及的扭振响应模型、电气和蒸汽激振模型、疲劳损伤模型、热暂态模型、扭振振幅监测、模型参数识别及系统功能进行了设计和研究,对TSA的实现提供了坚实的基础。 In this paper a digital simulation model of torional stress analyzer (TSA) is presented, which is required for the prediction of turbine-generator shaft stress and fatigue. The model includes torsional vibration response, electrical and mechanical excitation, stress fatigue analysis and parameter identification.
