Problems solved by technology

However, building a machine learning model requires a large number of fault samples of wind turbines, and it is difficult to obtain fault samples in practice, which hinders the application of machine learning in practice.
Expert systems usually require a large amount of expert knowledge to build a wind turbine fault diagnosis expert system, but it is difficult to obtain a large amount of expert knowledge, and it is difficult to accurately describe the fault phenomenon of wind turbines
In addition, the expert system is too costly in subsequent updates and is not easy to maintain
It can be seen that the existing intelligent diagnosis methods for wind turbines have relatively large deficiencies, and it is difficult to implement them in practical applications.

Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the application clearer, the embodiments of the application will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0036] The intelligent state monitoring system of this application first collects the vibration data of the transmission chain (such as the main bearing, gearbox, generator) of the wind turbine, blade vibration data, tower overturning data, tower foundation settlement data, and wind turbine speed through the edge data acquisition equipment. Pulse data, power, wind speed, etc. The edge data acquisition equipment will preprocess the original data, including: extracting the characteristic parameters of the vibration data (such as early warning evaluation value, peak-to-peak value, effective va...

Description

technical field [0001] The application relates to an intelligent condition monitoring system for wind turbines based on multiple templates, which is applicable to the technical field of wind turbine monitoring. Background technique [0002] Wind power can convert wind energy into electrical energy, and is the main means for human beings to utilize wind energy, a clean energy source. At present, the proportion of wind power in the field of electric energy is increasing year by year. According to the "Statistical Briefing on China's Wind Power Lifting Capacity in 2018", as of the end of 2018, the cumulative installed capacity of wind turbines in my country was about 210 million kilowatts, and the installed capacity of wind turbines maintained a steady growth trend. In the wind power generation system, the wind turbine is the core equipment and plays an important role in converting wind energy into electrical energy. At present, wind turbines are mainly divided into three typ...
