| 摘 要： | 在水电机组状态监测与诊断系统中，轴心轨迹是诊断机组状态的一个重要特征。文中 运用灰色系统理论的关联度分析方法，利用不变性矩作为特征向量，对水轮发电机组轴心轨 迹的自动识别进行了探讨。详细介绍了方法的原理和实际应用步骤，对3类典型的轴心轨迹 的自动识别进行了仿真试验，结果表明，该法是有效、可行的。

| Abstract: | Axis orbit is an important characteristic to be used to diagnose the unit condition in the condition monitoring and diagnosis system of hydroelectric generating set.A new method,which uses grey theory and eigenm atrix com bined with moment invariants to identify the orbit of shaft centerline of hydroelectric generating set is discussed in this paper.The principle and its application procedure of the method are introduced in detail.Simulation results of autom atic identification for three typical axis orbits are provided.It is proved that the m ethod is effective and practicable. This is the Planed Project Financed by the Key Members in U niversities of Ministry of Education. |
