摘要

针对直驱风电机组与弱交流电网之间相互作用引发的次同步振荡问题,提出一种鲁棒复合控制的直驱风机次同步振荡抑制策略。首先,根据虚拟同步机（VSG）控制原理构建网侧逆变器序阻抗模型,根据其幅频特性曲线判断系统稳定性。然后,分析得出电流环PI控制器作为关键因素加剧了振荡,故采用自抗扰（ADRC）控制器进行替换,同时设计基于不确定性和扰动估计器（UDE）的附加阻尼控制器,以达到协同抑制扰动的目的。最后,利用Matlab/Simulink平台构建相应的单一控制与复合控制模型,仿真结果证明了鲁棒复合控制策略的可行性。

Abstract

Aimed at the sub-synchronous oscillation issues arising from the interaction between direct-drive wind turbines and weak AC grids, a robust composite control strategy for suppressing sub-synchronous oscillation is proposed. First, the virtual synchronous generator （VSG） control principle is used to construct the grid-side inverter sequential impedance model, and the system stability is assesed according to its amplitude-frequency characteristic curve. Then, the analytical derivation analysis concludes that the PI controller in the currentloop exacerbates the oscillations as a key factor, which is replaced by active disturbance rejection control （ADRC）. Additionally an additional damping controller based on the uncertainty and disturbance estimator （UDE） is designed to synergistically suppress the disturbances. Finally, the corresponding single control and composite control simulation models are established based on the Matlab/Simulink platform, and simulation results verify the applicability and practicality of the robust composite control strategies.
