基于Weibull核函数与MCSVDD的轮毂电机故障诊断

open access: yesZhendong Ceshi yu Zhenduan
为监测分布式驱动电动汽车中轮毂电机运行状态,确保整车运行安全,提出一种基于改进的多类支持向量数据描述(multi⁃class support vector data description,简称MCSVDD)的轮毂电机故障诊断方法。首先,针对MCSVDD算法的改进,基于近邻传播(affinity propagation,简称AP)聚类算法提出了MCSVDD以“距离类内簇中心最小”的类别判断法则,并基于Weibull函数构造了Weibull核函数,用于优化数据描述模型;其次 ...

考虑多源协同的主动配电网故障恢复策略

open access: yesGaoya dianqi
随着科技的发展,主动配电网中面临了多项重要问题,首先,随着大量柔性负荷和电动汽车的接入,负荷种类显著多元化,增加了电网管理的复杂性。其次,可再生能源的随机性和波动性对电网的故障恢复提出了重要挑战。为了应对这些问题,研究提出了一种针对各种能源互动的主动配电网故障恢复策略。该策略建立了一个优化模型,以最大数量可控分布式电源行动和最小功率损失为目标,同时满足系统安全约束。为了建立该模型,使用了改进的二进制粒子群算法和遗传算法。通过在IEEE33节点配电网模型上的仿真分析,实验结果表明 ...
