Abstract

The invention provides a wind turbine generator tower drum load prediction method and system. The method comprises the following steps: 1, obtaining load data corresponding to a wind turbine generator in each wind power state in a to-be-detected region in a preset time under different wind power states; step 2, collecting a wind power value corresponding to the maximum load value of each group, a torque value of the tower drum and a bending moment value of the tower drum from each group of load data to obtain multiple groups of operation data; step 3, obtaining a quadratic function image between the wind power value and the load according to the obtained multiple groups of operation data; step 4, predicting the load of the tower drum of the wind turbine generator according to the obtained quadratic function image; according to the method, the load can be effectively predicted, the complexity of previous prediction is avoided, the load can be quickly and intuitively predicted, and the prediction convenience is improved.

Description

technical field [0001] The present invention relates to the technical field of wind turbines, in particular to a method and system for predicting tower loads of wind turbines. Background technique [0002] The wind power supply consists of wind turbines, towers supporting generators, battery charge controllers, inverters, unloaders, grid-connected controllers, battery packs, wind power flanges, etc.; wind turbines include wind turbines, power generators The wind wheel consists of blades, hubs, reinforcements, etc.; it has functions such as blades being rotated by the wind to generate electricity, and the head of the generator to rotate. Wind speed selection: Low wind speed wind turbines can effectively improve the wind energy utilization of wind turbines in low wind speed areas. [0003] Existing prediction methods usually need to test a lot of data to make predictions, which are relatively complicated and cannot be accurately and intuitively predicted. Contents of the in...
