DIAGNOSIS AND PROGNOSIS OF ROTOR THERMAL SENSITIVITY |
摘要 |
A system and method for diagnosis and prognosis of thermal sensitivity in a rotor of an electrical machine. A first system is provided for evaluating thermal sensitivity in a rotor of an electrical machine and includes: an input system for obtaining vibration data and field current from the rotor and for obtaining a set of operating parameter; a system for calculating a relationship between vibration and field current; an evaluation system for determining whether the relationship is significant; and a system for issuing a notification of thermal sensitivity in response to a determination of a significant relationship. A second system includes a system for calculating a series of relationships between vibration and field current over a period of time; an evaluation system for determining whether a change in the series of relationships over the period of time is significant; and a system for issuing a notification of thermal sensitivity in response to a determination of a significant change in the series of relationships. |
