摘要

针对最大功率点跟踪（MPPT）与扭振控制回路之间的耦合及运行过程扰动抑制问题,提出一种基于线性自抗扰的风电机组MPPT与扭振协同控制方法。设计未知输入观测器并结合牛顿-拉夫逊算法为叶尖速比法MPPT估计有效风速,设计卡尔曼滤波器为扭振控制回路估计传动链扭转速度。在FAST中开展仿真研究。仿真案例表明：相较于传统方法,所提出方法发电量提升1.58%,引入扭振控制器后,扭转速度和扭角的标准差分别降低31.06%和0.50%,提高MPPT性能的同时抑制传动链扭振。

Abstract

Aiming at the problem of coupling between MPPT and torsional vibration control loop and disturbance suppression in the operation process, a cooperative control method of MPPT and torsional vibration of wind turbine based on linear active disturbance rejection is proposed. The unknown input observer is designed and combined with the Newton-Raphson algorithm to estimate the effective wind speed for the tip speed ratio method MPPT, and the Kalman filter is designed to estimate the torsional speed of the drivetrain for the torsional vibration control loop. The simulation research is carried out based on the 5 MW wind turbine model in FAST. The simulation case shows that compared with the traditional method, the power generation of the proposed method is increased by 1.58%. After the introduction of the torsional vibration controller, the standard deviation of the torsional speed and torsion angle is reduced by 31.06% and 0.50%, respectively, which improves the MPPT performance and suppresses the drivetrain torsional vibration.
