Abstract	本申请属于发电机技术领域，具体涉及一种发电机定子槽楔松紧度检测方法、设备和存储介质，其中的方法包括：S10、获取待检测槽楔被敲击后由声音传感器采集得到的原始声波数据；S20、对所述原始声波数据进行预处理，得到敲击声波数据；S30、对所述敲击声波数据进行目标特征提取，得到声波特征值；其中，所述目标特征包括频带幅值面积、频谱质心、波形因子、第三峰值频率、第五峰值频率；S40、将所述声波特征值输入到训练好的分类器中进行敲击声波特征分类，得到发电机定子槽楔松紧度检测结果。本申请提出的方法对发电机定子槽楔松紧度无损检测，不仅提高了检测效率和准确率、还降低了检测成本。
Other Abstract	The invention belongs to the technical field of generators, and particularly relates to a generator stator slot wedge tightness detection method and device and a storage medium, and the method comprises the steps: S10, obtaining original sound wave data collected by a sound sensor after a to-be-detected slot wedge is knocked; s20, preprocessing the original sound wave data to obtain knocking sound wave data; s30, performing target feature extraction on the knocking sound wave data to obtain a sound wave feature value; wherein the target characteristics comprise a frequency band amplitude area, a frequency spectrum centroid, a waveform factor, a third peak frequency and a fifth peak frequency; and S40, inputting the sound wave characteristic value into a trained classifier to carry out knocking sound wave characteristic classification so as to obtain a generator stator slot wedge tightness degree detection result. According to the method provided by the invention, the tightness of the slot wedge of the generator stator is subjected to nondestructive detection, so that the detection efficiency and accuracy are improved, and the detection cost is reduced.
