Highlights Vascular complication is one of the most important causes of death in diabetes patients. Arterial stiffness plays a key role in the progress of diabetes vascular complication; therefore, the improvement of arterial stiffness could inhibit the process of atherosclerosis and reduce the burden of diabetes vascular complications This study first

宽频振荡紧急控制是保障风电系统安全运行的“兜底”措施之一。由于风电系统非线性强度大及运行工况多变,难以建立宽频振荡在线风险评估的解析模型。为此,提出了基于数据驱动的宽频振荡风险在线评估方法及紧急控制策略。首先,设计了能够应对宽频振荡多模态和时变特征的宽频相量检测算法,为后续宽频振荡特征评估提供数据支撑;其次,利用最大李雅普诺夫指数作为宽频振荡动态演化趋势的量化指标,并根据风电机组模态阻抗的负电阻效应在线辨识宽频振荡源;然后,融合宽频振荡特征辨识结果,提出宽频振荡风险在线评估策略 ...
