摘要基于双馈感应发电机的风力发电机组容易受到次同步振荡的影响。次同步控制干扰是近年来出现的一种次同步振荡现象，指的是双馈风力发电机组转子侧变流器与固定串联补偿输电线路之间的相互作用。本文对次同步控制交互进行了定量化分析，并创建次同步控制交互触发条件来检测次同步控制交互的存在。然后将次同步控制交互触发条件与阻抗扫描相结合，有效地识别感应发电机效应和次同步控制交互作用。在此基础上，提出了一种次同步控制交互触发的阻尼控制策略，有效地缓解了次同步控制交互。通过时域仿真，验证了该控制策略的抑制能力和鲁棒性。
Abstract Doubly fed induction generator-based wind turbines are vulnerable to subsynchronous oscillations. Subsynchronous control interaction is a recently emerging subsynchronous oscillation phenomenon, which means the interaction between the rotor-side converter of a doubly fed induction generator-based wind turbine and a fixed series-compensated transmission line. In this article, subsynchronous control interaction is quantitatively analyzed, and an subsynchronous control interaction-triggered condition is created to detect the existence of subsynchronous control interaction. The subsynchronous control interaction-triggered condition is then combined with impedance scanning to effectively identify the induction generator effect and subsynchronous control interaction. Further, a subsynchronous control interaction-triggered damping control strategy is developed to effectively alleviate subsynchronous control interaction. The mitigation ability and the robustness of the presented control strategy are, respectively, verified by time-domain simulation.
