摘要

针对风电机组传动链动态特性分析中通常忽略发电机电磁转矩激励的问题

综合考虑叶片柔性、齿轮非线性刚度和轴承弹性支承等时变、非线性因素

结合双馈异步发电机矢量控制及叶片变桨控制

采用集中参数法和子结构法建立风电机组传动链机-电-气-控全耦合动力学模型。通过时域求解

研究传动链系统的动态响应特性。结果表明

在电网电压跌落条件下

不同叶片面内弯曲阻尼刚度系数下的发电机转速均有大幅震荡

但随着叶片面内弯曲阻尼刚度比值的增大

发电机转速波动收敛较快

适当增大叶片柔性对发电机暂态稳定性有积极影响;此外

电磁转矩激励会引起传动链机械部件振动加剧

增大齿轮疲劳损伤。

Abstract

In order to solve the problem that the electromagnetic torque excitation of generators is usually ignored in the analysis of dynamic characteristics of wind turbine drivetrain

the time-varying and nonlinear factors including blade flexibility

gear nonlinear stiffness and bearing elastic support

etc. are comprehensively considered and combined with the variable pitch control of wind turbine blades and the generator vector control

and a fully coupled mechanical-electrical-pneumatic-control dynamic model of the wind turbine drivetrain is established by using lumped parameter method and substructure method in the paper. The dynamic response characteristics of the drivetrain system are studied by utilizing time-domain simulation technology in the paper. The results show that the mechanical speed of the generator in the different ratio of bending damping to stiffness in the blade in-plane has significant oscillations under the condition of grid power voltage sag

but with the increase of the ratio of bending damping to stiffness in the blade in-plane

the mechanical speed fluctuation of the generator converges rapidly

and the appropriate increase of blade flexibility has a positive impact on the transient stability of the generator. Besides

electromagnetic torque excitation can aggravate vibration of mechanical components in the drivetrain

and increase gear fatigue damage.
