Problems solved by technology

[0003] At present, the preventive maintenance of wind turbines is mainly maintenance after failure and regular maintenance (such as semi-annual maintenance and annual maintenance), but there is no online life prediction and corresponding preventive maintenance and maintenance system for the components of the whole machine, so it is difficult to realize the The role of early warning of unit life cannot scientifically judge the timing of unit maintenance and provide reasonable prevention and maintenance methods, resulting in high fan maintenance costs and unreasonable spare parts warehouse planning

Embodiment Construction

[0039] Various example embodiments will now be described more fully with reference to the accompanying drawings, wherein like numerals refer to like parts throughout.

[0040] figure 1 A flow chart showing a life prediction method for fan components according to an embodiment of the present invention.

[0041] refer to figure 1 , in step 101, the characteristic parameters of the components of the fan are collected.

[0042]Characteristic parameters of various components of the fan can be collected by controlling various sensors installed in the fan. For fan components, characteristic parameters mainly include electrical characteristic parameters (such as current, voltage, frequency, etc.), mechanical characteristic parameters (such as vibration signals, magnetic field signals, speed signals, etc.), process parameters (such as wind speed, power , temperature, etc.).

[0043] In step 102, according to the characteristic parameters of the components of the wind turbine collec...

Abstract

The invention provides a service life forecasting method and a service life forecasting system of fan components. The service life forecasting method of the fan components comprises the steps of: acquiring characteristic parameters of the fan components; determining the components that are at a non-ineffective stage according to the characteristic parameters acquired; determining the rest service life region of the components that are at the non-ineffective stage; and performing on-line rest service life forecasting on the components of which the rest service life region is within a preset service life region. According to the method and the device, the rest service life of the fan components can be acquired on line so that a fan user can be guided to process potential fan faults in time, thus ensuring the safety and the reliability in operation of a fan.

Description

technical field [0001] The invention relates to the field of wind power generation. More specifically, it relates to a method and system for life prediction of fan components. Background technique [0002] With the development of technology, the attention and utilization of renewable energy are increasing. Among them, wind power is a relatively mature energy technology. [0003] At present, the preventive maintenance of wind turbines is mainly maintenance after failure and regular maintenance (such as semi-annual maintenance and annual maintenance), but there is no online life prediction and corresponding preventive maintenance and maintenance system for the components of the whole machine, so it is difficult to realize the The role of unit life early warning cannot scientifically judge the timing of unit maintenance and provide reasonable prevention and maintenance methods, resulting in high fan maintenance costs and unreasonable spare parts warehouse planning.
