Title:
ロバスト制御に基づく風力発電ユニットの空力アンバランス負荷制御方法
Document Type and Number:
Japanese Patent JP7432215
Kind Code:
B2
Abstract:
To provide an aerodynamic unbalance load control method for a wind power generation unit based on robust control.SOLUTION: An aerodynamic unbalance load control method for a wind power generation unit based on robust control includes the steps of: obtaining the amount of measurement of a main shaft load of a measurement waiting station room; converting a main shaft load measurement of an engine room into an effective input of a robust independent variable pitch controller by means of coordinate transformation of the engine room; establishing a product perturbation model for aerodynamic unbalance of a wind power generation unit; calculating a robust independent variable pitch controller; and obtaining an input pitch angle of a wind power generation unit control system by means of coordinate inverse transformation of the engine room. The problem that a sensor is mounted on a rotary part is solved by using the amount of bending moment measurement based on the engine room as a feedback input of the controller. Based on Coleman conversion, one controller completes aerodynamic unbalance control. Conventional imperfect decoupling and nonlinear problems of a system are solved by adopting a multi-input, multi-output, and robust independent variable pitch control policy.SELECTED DRAWING: None
