一种风力发电机性能检测系统及其检测方法
By collecting and analyzing multi-source time-series data inside and outside the nacelle, weak areas and potential damage to the wind turbine sealing system are identified, and a maintenance priority list is generated. This solves the problem of hidden damage during typhoons and improves the operational reliability and lifespan of the wind turbine.

Abstract
本发明公开了一种风力发电机性能检测系统及其检测方法，具体涉及发电机密封性检测技术领域，用于解决现有技术难以有效检测台风过境时机舱密封系统隐性损伤的问题；通过同步采集机舱内外多源时序数据，基于气压数据识别瞬时气压反转事件，结合声学振动信号互信息熵变化生成密封薄弱区概率分布，进而通过光路透射率递归特征分析确立渗入性侵湿可能性，最后对绝缘电阻值进行分区趋势分析生成隐性损伤指标向量，通过阈值比对输出维护优先级清单来实现对风力发电机密封状态和绝缘性能的精准评估与预警。
