Research on Online Fault Diagnosis Technology of Wind Turbine

Wind power is a renewable and clean energy, but for the transmission system of wind turbines operating at high altitude, its equipment inspection, maintenance and troubleshooting are more difficult, and if the fault is not found in time, it may cause more serious economic losses. Therefore, how to better apply the online fault monitoring and prevention technology to the operation and maintenance management of wind turbines is particularly important. This paper mainly combined the mechanical transmission system of a wind turbine to carry out online fault diagnosis technology and system research and development, mainly including: using vibration acceleration signal as monitoring signal to build a fault monitoring system platform; The relationship between mechanical fault and vibration of wind turbine, the principle, implementation, application analysis and development direction of online fault diagnosis technology are described. The configuration scheme and software and hardware requirements of online fault diagnosis technology of wind turbine are proposed for different models, and the fault diagnosis analysis process is discussed based on wind turbine operation data and engineering fault examples.
