This paper proposes an adaptive supplementary controller based on the multiple-model adaptive control (MMAC) approach to mitigate subsynchronous resonance (SSR) induced by a Type III wind system connected to a series-compensated transmission line. The proposed supplementary controller has two levels; the first level is a set of controllers designed using standard linear control methods, and the second level is a supervisory controller that selects the level-one controller based on the system conditions. A systematic approach is introduced for simultaneous coordination of parameters of the proposed supplementary controllers in a nonaggregated wind system. The aim of this coordination approach is to stabilize the system by moving the unstable modes to the left-hand plane while minimizing the controller gain values to reduce the sensitivity of the wind generator to the small disturbances. To evaluate the performance of the proposed controller, small-signal stability of the test system is studied using its comprehensive dynamic model. Time-domain simulation results show the effectiveness of the proposed supplementary controller to mitigate subsynchronous oscillations in a wide range of operating conditions.

减轻III型风系统引起的次同步共振

本文提出了一种基于多模型自适应控制(MMAC)方法的自适应辅助控制器,以减轻由连接到串联补偿输电线路的III型风系统引起的次同步共振(SSR)。提议的辅助控制器有两个级别;第一级是使用标准线性控制方法设计的一组控制器,第二级是根据系统条件选择一级控制器的监控控制器。引入了一种系统方法,用于在非聚集风系统中同时协调建议的辅助控制器的参数。这种协调方法的目的是通过将不稳定模式移动到左侧平面来稳定系统,同时最小化控制器增益值以降低风力发电机对小干扰的敏感性。为了评估所提出的控制器的性能,使用其综合动态模型研究了测试系统的小信号稳定性。时域仿真结果表明,所提出的辅助控制器在宽范围的工作条件下缓解次同步振荡的有效性。
