[0038]The present invention will be further described below with reference to the accompanying drawings and examples.
[0039]ReferFigures 1 to 10The present invention provides an impeller speed fault tolerance monitoring method based on a flange gap sensor, comprising the steps of:
[0040]S1, the wind turbine collects the first impeller speed measured by the absolute value of the speed encoder by the speed monitoring module in real time, and transmitted to the main controller processor;
[0041]S2, the flange gap sensor collection signal is mounted with each blade of the wind turbine, and the flange gap sensor collector 13 collects the signal of the flange gap sensor to transmit the acquired flange gap data. To the hipporator control processor;
[0042]S3, the modulator control processor calculates the second impeller rotation according to the collected flange gap data, and specifically includes the following process:
[0043]S3.1, the number of blades of the winder set is m, and the target flan...
