Detecting Faults in Turbine Generators |
| 摘要 |
Turbine generator faults can be detected by receiving a current signal from the turbine generator, and synchronously sampling the current signal to obtain a set of current signal samples that are evenly spaced in the phase domain, in which phase differences between adjacent current signal samples in the set of current signal samples are substantially the same. The process includes generating a frequency spectrum of the current signal samples, identifying one or more excitations in the frequency spectrum, and detecting a fault in the turbine generator based on the one or more excitations in the frequency spectrum. |

1. A method for detecting turbine generator faults, the method comprising:
receiving a current signal from a turbine generator; synchronously sampling the current signal to obtain a first set of current signal samples that are evenly spaced in the phase domain, in which phase differences between adjacent current signal samples in the first set are substantially the same; generating a frequency spectrum of the first set of current signal samples; identifying one or more excitations in the frequency spectrum; and detecting a fault in the turbine generator based on the one or more excitations in the frequency spectrum. |
