基于主导特征辨识的双馈机组风电场次同步振荡等值建模方法

Gaoya dianqi
大型双馈风电场通常建设在偏远地区，采用线路串联电容补偿能够减少能量损失，然而会引起系统发生次同步振荡，使得对双馈风电场的等值建模出现困难。文中提出一种基于主导特征辨识的双馈机组风电场次同步振荡等值建模方法。在双馈风电场发电系统数学方程的基础上建立小信号模型，利用特征值分析法识别双馈风电场的次同步振荡模式，并通过半实物仿真验证了主导特征变量对次同步振荡模式的影响。以次同步振荡模式的主导特征变量作为双馈风机变量指标，根据层次聚类算法进行分群。通过容量加权法计算等值模型的参数 ...

基于主热流分析的三芯电缆接头热点温度反演辨识方法及试验验证

Gaoya dianqi
电力电缆由电缆本体和电缆接头组成，电缆接头内部的温升是影响电力电缆线路载流能力的关键因素。针对电缆接头材料参数分散性大和热流扩散规律不明显等问题，文中提出了一种基于主热流分析的电缆接头热点温度反演辨识方法，以准确辨识接头内部的热点温度。首先建立了10 kV三芯电缆及接头的有限元仿真计算模型，得到温度场分布规律。其次通过分析电缆接头的热流扩散规律，建立了电缆本体的热路模型，并采用正交试验法设计训练样本和测试样本，确定了距离接头端部0.1 m和2.0 m的2个导体特征温度点 ...
