METHOD AND A SYSTEM CAPABLE OF MONITORING A SYNCHRONIZING DEVICE WHICH DISTINGUISHES THE RESONANCE FREQUENCY BASED ON THE MONITORED VOLTAGE

摘要

PURPOSE: A method and a system capable of monitoring a synchronizing device are provided to produce a wound line degradation indicator based on the distinguished resonant frequency and the expected resonant frequency.;CONSTITUTION: A signal generator injects a narrow band sinusoidal signal in a field magnet terminal of the field magnet wound line(310). A monitoring module(320) monitors the voltage at the counter terminal of the ground. A spectrum analyzer distinguishes the resonant frequency of the field magnet would line based on the field magnet voltage of the monitored ground(330). An estimation module calculates the difference between the distinguished resonant frequency and the estimated resonant frequency(340).;COPYRIGHT KIPO 2013;[Reference numerals] (310) Injecting a narrow band sinusoidal signal in a first end of field magnet winding of a synchronizing device; (320) Monitoring the voltage at a second end of the field magnet winding to the ground; (330) Distinguishing a resonant frequency based on the monitored voltage; (340) Generating a good winding indicator based on the distinguished resonant frequency and a predicted resonant frequency
