Abstract

The embodiment of the invention provides a wind turbine generator blade fault early warning method, and relates to the field of wind turbine generators. The problem that internal damage and faults of wind turbine generator blades are difficult to evaluate is solved. The method comprises the steps of obtaining a first score representing a wind speed-power operation condition, a second score representing a wind speed-hub rotation speed operation condition and a third score representing a wind speed-tip speed ratio operation condition according to multiple groups of wind speed-power, multiple groups of wind speed-hub rotation speed and multiple groups of wind speed-tip speed ratios; according to the multiple groups of axial second-level vibration data, a fourth score representing the operation condition of the axial second-level vibration data is obtained; and determining the state of the wind turbine generator blade according to the first score, the second score, the third score and the fourth score. A first score, a second score, a third score and a fourth score are obtained according to wind speed-power, wind speed-hub rotating speed, wind speed-tip speed ratio and axial second-level vibration data, then the state of the wind turbine generator blade is determined according to the scores, and the evaluation difficulty is reduced.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a method for early warning of blade failures of wind power generators. Background technique [0002] Wind energy is a clean and renewable energy. In recent years, the wind power industry has developed rapidly. However, due to many reasons such as the harsh environment of the wind farm, the damage to the large components of the wind turbine has caused great obstacles to the wind power industry, especially the downtime and replacement caused by the cracking of the blades. Therefore, it is imminent to control the operating status of wind turbine blades. In related technologies, there is a problem that it is difficult to evaluate the dominant faults of wind turbine blades. Contents of the invention [0003] The object of the present invention includes, for example, to provide a wind turbine blade fault early warning method, which can. [0004] Embodiments of the present inve...
