Embodiment Construction

[0134] figure 1 The diagram shows the detection of 100 as Figure 4 to Figure 9 An abnormal condition 120 of a blade 22 on a wind turbine generator 12 is shown in FIG. Method 100 includes an act of measuring 200 sensory input 140 from wind turbine generator 12 .

[0135] The method includes an act of identifying 300 a signature of an abnormal condition 155 , such as experienced by the blade 22 , from the sensory input 140 .

[0136] figure 2 Additional aspects of signature 150 (ie, exception signature 155 ) identifying exception condition 120 are illustrated.

[0137] The act of measuring 200 may involve the act of synchronizing 240 sensory input. The act of synchronizing 240 could in principle be performed as part of identifying 300 .

[0138] As will be illustrated, the act of identifying 300 may involve identifying signature 150 by comparing normal signature 152 or pre-calibrated signature 154 of sensory input 140 to measured signature 150 of sensory input 140 .

Abstract

A method of detecting an abnormal condition, such as a blade or a rotor, on a wind turbine generator is disclosed. A system for detecting an abnormal condition, such as a blade or a rotor, on a wind turbine generator is also disclosed.

Description

technical field [0001] The present invention relates to a method of detecting abnormal conditions, eg blades or rotors, on a wind turbine generator. The invention also relates to a system for detecting abnormal conditions such as blades or rotors on a wind turbine generator. Background technique [0002] The operation of a wind turbine generator benefits from information about operating conditions. To this end, a large number of auxiliary diagnostics with specific purposes have been developed and realized. [0003] In an example, weather forecasts based on meteorological data are refined with the specific purpose of predicting weather conditions. [0004] In another example, the installation of meteorological equipment, such as LiDAR or radar, to observe weather conditions faced by wind turbine generators is costly and complex. [0005] Precipitation, including heavy precipitation, can be detected or identified by rain gauges; and / or modeled in conjunction with meteorolog...
