SYSTEM AND METHOD FOR DETECTING ANOMALIES OF MAIN SHAFT BEARING OF WIND POWER GENERATOR

摘要

To provide a system and a method for detecting anomalies of a wind power generator main shaft bearing, which enhance accuracy in detection of damage to a main shaft bearing of a wind power generator.SOLUTION: A wind power generator main shaft bearing anomaly detection system is provided, comprising: a detection unit for detecting vibration of a main shaft bearing of a wind power generator; and a diagnostic unit configured to set a frequency band for assessing vibration information detected by the detection unit, and perform main shaft bearing anomaly determination processing using the vibration information limited to the frequency band set thereby.SELECTED DRAWING: Figure 10
