To effectively judge the vibrational stationary state of hydropower units, the whirling characteristics of the rotor vibration and the evaluation method of stability of shaft vibration were studied. The theoretical expression of instantaneous whirling velocity was derived, and the characteristic parameters of whirling velocity were analyzed. A holographic whirling velocity analysis method for shaft vibration was proposed. The whirling characteristics indicators and vibration stability evaluation index of shaft vibration were established. Finally, the theory of this paper was applied to the shaft vibration data analysis of Zhejiang Xianju pumped storage power station. The key characteristic indicators of vibration were extracted and the shafting stationary was evaluated. The results show that the established characteristic indicators have good performance in evaluating the stationary of shaft vibration, and have broad application prospects for the monitoring and performance evaluation of actual hydropower units.

为有效判别水电机组振动平稳状态,研究了转子振动过程的涡动特征和轴系振动平稳性评估方法。首先推导了瞬时涡动角速度的理论表达结果,并分析涡动角速度的特征参数,然后提出轴系振动过程的全息涡动速度分析方法,建立轴系振动过程的涡动特征指标和振动平稳性评价指标,最终将本文理论用于浙江仙居抽水蓄能电站轴系振动数据分析,提取振动的关键涡动特征指标并评估轴系平稳性。结果表明,所建立的特征指标具有良好的轴系振动平稳性表达能力,对于实际水电机组振动状态监测和性能评估有广阔的应用前景。

为有效判别水电机组振动平稳状态,研究了转子振动过程的涡动特征和轴系振动平稳性评估方法。首先推导了瞬时涡动角速度的理论表达结果,并分析涡动角速度的特征参数,然后提出轴系振动过程的全息涡动速度分析方法,建立轴系振动过程的涡动特征指标和振动平稳性评价指标,最终将本文理论用于浙江仙居抽水蓄能电站轴系振动数据分析,提取振动的关键涡动特征指标并评估轴系平稳性。结果表明,所建立的特征指标具有良好的轴系振动平稳性表达能力,对于实际水电机组振动状态监测和性能评估有广阔的应用前景。

To effectively judge the vibrational stationary state of hydropower units, the whirling characteristics of the rotor vibration and the evaluation method of stability of shaft vibration were studied. The theoretical expression of instantaneous whirling velocity was derived, and the characteristic parameters of whirling velocity were analyzed. A holographic whirling velocity analysis method for shaft vibration was proposed. The whirling characteristics indicators and vibration stability evaluation index of shaft vibration were established. Finally, the theory of this paper was applied to the shaft vibration data analysis of Zhejiang Xianju pumped storage power station. The key characteristic indicators of vibration were extracted and the shafting stationary was evaluated. The results show that the established characteristic indicators have good performance in evaluating the stationary of shaft vibration, and have broad application prospects for the monitoring and performance evaluation of actual hydropower units.
