  • Patent number: 10570887
    Abstract: Disclosed herein is a vibration monitoring and diagnosing system for monitoring conditions of a wind power generator and diagnosing a defective portion thereof using vibration characteristics obtained from acceleration sensors mounted to the wind power generator. A vibration-based defect detecting method may include: collecting vibration data of the wind power generator using the plurality of sensors; extracting a first characteristic value of a time domain based on the vibration data; extracting characteristic values in one or more frequency bands for a location of each sensor in a frequency domain or an envelope frequency domain if the first characteristic value is greater than a preset alarm setting value; and determining that a defect is present when at least one characteristic value of the characteristic values is greater than a preset normal value.

  • Patent number: 10481034
    Abstract: An apparatus for diagnosing abnormal operation of a rotor. The apparatus includes a first sensor provided around a shaft in order to detect vibration occurring while the shaft provided in a rotor axially rotates, a second sensor to generate a periodic pulse signal over time whenever the shaft rotates once, and a controller to determine an operation state of the rotor by receiving signals detected by the first and second sensors. When an aperiodic pulse signal is detected in the rotor, the controller determines a position of the rotor at which the aperiodic pulse signal is generated, and a display indicates the position of the rotor in which the aperiodic pulse signal is generated, according to information calculated by the controller.
