摘要

摘要本研究旨在评估不同ISO VG 320油配方用于2.5 MW风力发电机齿轮箱的效率。在一个定制的测试平台上，对矿物油和聚阿尔法烯烃(PAO)两种市售润滑剂进行了实际操作条件下的测试。测量结果表明，矿物润滑剂的整体效率高于PAO润滑剂，但效率程度的差异仅为0.1%。详细的油分析表明，矿物润滑剂产生了更多的磨损颗粒。采用功率损失模型对齿轮箱的效率进行了预测，模型结果与实验结果吻合较好。研究得出结论，矿物油在齿轮箱较窄的工作温度范围内粘度较低，因此比PAO油具有更高的效率。然而，值得注意的是，观察到的效率差异可能部分归因于测量的不确定性，以及矿物润滑剂在工作温度下的粘度比PAO润滑剂低10%的事实。

Testing and modelling of a 2.5 MW wind turbine gearbox: Influence of lubricant formulation

Abstract This study aimed to evaluate the efficiency of different ISO VG 320 oil formulations used in a 2.5 MW wind turbine gearbox. Two commercially available lubricants, a mineral oil and a polyalphaolefin (PAO) lubricant, were tested under realistic operating conditions using a customized test rig. Measurements showed that the overall efficiency of the mineral lubricant was higher than that of the PAO lubricant, but the difference was only 0.1% in degree of efficiency. Detailed oil analysis revealed that the mineral lubricant generated more wear particles. A power loss model was also implemented to predict the efficiency of the gearbox, and the results of the model were found to be in agreement with the experimental results. The study concluded that the mineral oil presented higher efficiency than the PAO oil due to its lower viscosity within the narrow operating temperature range imposed on the gearbox. Nevertheless, it is important to note that the observed differences in efficiency may be attributed, in part, to measurement uncertainties and the fact that the mineral lubricant has 10% lower viscosity at the operating temperature compared to the PAO lubricant.
