Abstract
The present application belongs to the field of monitoring technology, and discloses a stator monitoring method and monitoring system for offshore wind turbines. A stator monitoring method and monitoring system for offshore wind turbines, comprising the following steps: Step 1: Arrange a signal receiver at each position corresponding to the slot wedge of the stator to obtain the sound signal of the generator when it is working in real time; Step 2: Extract the features of the sound signal collected by each signal receiver to obtain the audio features of each signal receiver; In this technical solution, it is possible to accurately determine whether the slot wedge is really loose. Therefore, this solution allows continuous monitoring of the stator slot wedge when the generator is running, so as to timely discover and handle the operating faults of the generator.
