摘要:
水力发电是一种利用水流能量转化为电能的清洁能源技术,水电站泵组设备运行的稳定性和安全性至关重要。研究通过搭建离心泵轴承试验台,采用振动传感器采集数据,并运用CNN模型进行特征提取和故障诊断,实现了对泵组设备运行状态的实时监测。实验结果显示,CNN模型在实测集上的轴承故障诊断准确度、召回率和精确度分别达0.961、0.956、0.972,均优于SVM和决策树模型,展现了强大的故障诊断能力。在训练数据稀缺(200组)的情况下,CNN模型的准确度仍大于0.85。
Abstract:
Hydropower generation is a clean energy technology that converts the energy of water flow into electrical energy. The stability and safety of the operation of the pump set equipment in hydropower stations are of vital importance. The study established a centrifugal pump bearing test bench, collected data using vibration sensors, and used a CNN model for feature extraction and fault diagnosis, achieving real-time monitoring of the operating status of pump equipment. The experimental results show that the accuracy, recall, and precision of the CNN model for bearing fault diagnosis on the measured set are 0.961, 0.956, and 0.972, respectively, which are superior to SVM and decision tree models, demonstrating strong fault diagnosis capabilities. In the case of scarce training data (200 sets), the accuracy of the CNN model is still greater than 0.85.
