摘要

提出了一种风电系统齿轮箱效率下降的检测和估计方法。首先，通过指定的模型估计轴转矩。最后的估计扭矩用于检测齿轮箱效率下降通过一个比例动作回路。该方法在FAST编码模拟器上实现，该模拟器由美国国家可再生能源实验室的国家风力涡轮机中心设计。得到的结果提供了良好的故障检测和估计。

Residual generation for the gearbox efficiency drop fault detection in the NREL 1.5WindPact turbine

This paper presents an approach to detect and estimate drop of gearbox efficiency in wind turbine systems. First, shaft torque is estimated through a specified model. The last estimation torque is used to detect gearbox efficiency drop through a proportional action loop. The approach was implemented on FAST coded simulator, designed by the US National Renewable Energy Laboratory's National Wind Turbine Center. The obtained results provide a good fault detection and estimation.
