Embodiment Construction
[0035] The present invention proposes a multi-wind turbine operating state identification method based on migration component analysis. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0036] figure 1 It is a flow chart of the method for identifying the operating status of multiple wind turbines based on the migration component analysis; the specific implementation steps are as follows:
[0037] (1) Collect the SCADA data of multiple wind turbines in the wind farm, and designate one of them as the target wind turbine; in this embodiment, the rated power of 24 wind turbines is 1.5MW, the cut-in wind speed is 3m / s, and the rated wind speed is 10m / s, the cut-out wind speed is 25m / s, the data length is 1 year, and the data resolution is 15min; the historical data of the wind turbine SCADA system mainly includes: wind speed, wind direction, power, wind rotor speed, generator speed, yaw angle , pitch ang...
