Patent KR-20190099861-A (KR)
Inventor: LEE SANG BIN
IPC: G01R33/02
Filed: 2018-02-20
Abstract: Disclosed are a system and a method for diagnosing a damper bar fault of a three-phase alternating-current salient-pole synchronizer and a recording medium having a computer-readable program for performing the same. The system for diagnosing a damper bar fault of a three-phase alternating-current salient-pole synchronizer comprises a magnetic flux measurement unit, a frequency analysis unit, and a damper bar diagnosis unit. The magnetic flux measurement unit measures the magnetic flux in a gap between a rotor and a stator of a three-phase alternating-current salient-pole synchronizer. The frequency analysis unit calculates the magnitude of the measured magnetic flux in response to a frequency. The damper bar diagnosis unit diagnoses a fault of a damper bar of the three-phase alternating-current salient-pole synchronizer if the calculated magnitude of the magnetic flux is larger than a preset reference value in a preset diagnosis frequency band. The diagnosis frequency band (f_damper) is calculated by the equation of: f_damper = f_s +/- k(1-s/p)f_s = (1 +/- k(1-s)/p)fs, wherein f_s is a power frequency of the synchronizer, p is the number of pole pairs, s is a slip of the synchronizer, and k is a positive integer excluding multiples of 2p.
