基于改进YOLOv7的多尺度特征提取绝缘子缺陷检测算法

Gaoya dianqi
针对绝缘子图像缺陷尺寸小、背景干扰因素多、难易样本不平衡等问题，提出了一种多尺度融合的YOLOv7（MSF-YOLOv7）算法，并将其应用于输电线路绝缘子的缺陷检测。首先，通过多尺度卷积块注意力模块（multi scale-convolution block attention module，MS-CBAM），深度聚合带有丰富语义信息的特征图，提升网络对不同尺度目标的检测性能；其次，在主干网络利用新开发的全局空间金字塔池化（global spatial pyramid pooling-fast ...

海上风电柔性直流输电工程±525 kV海缆过电压特性研究

Gaoya dianqi
海上风电是目前最具发展潜力的可再生能源领域之一，而柔性直流送出是远海风电最主要的直流送出方式。随着经济社会发展，较低电压等级的海缆输送容量已经难以满足日益增长的远海风能的输送需求。在整个海上风电柔性直流送出系统中，直流海缆是非常重要的组成部分，其安全性直接关系到整个直流输电工程的安全可靠运行。因此对于海缆过电压特性进行全面、详实的研究显得尤为重要。为了便于分析直流海缆的过电压特性，依托于某±525 kV海上风电柔性直流输电项目，在PSCAD/EMTDC环境下搭建了基于模块化多电平换流器的两端柔性直流输电（
