基于图像分析的电能质量扰动边-云协同辨识框架
Edge-cloud Collaborative Identification Framework for Power Quality Disturbances Based on Image Analysis
摘要
Abstract
With the increase in the penetration rate of distributed sources and loads,the monitoring data of sensors is increasing dramatically.Power grid maintenance services propose a rapid response requirement in power quality data analysis.To achieve rapid response and highly accurate identification of power quality disturbance(PQDs),this paper proposes an edge-cloud collaborative identification framework for PQDs based on image analysis.Leveraging the latest advancements in the field of image analysis,the concept of double-phase Lissajous locus(DPLL)is proposed to convert PQDs signals into locus image with unique shapes.A lightweight convolutional neural network(CNN)with the same structure is deployed at the edge and cloud,respectively,to perform rapid response and training tasks.By sharing model weights of edge-cloud,this framework can achieve rapid and high-precision identification of PQDs.To continuously improve model performance,a depth CNN is designed to be deployed to the cloud for data labeling to assist model update.The experimental results demonstrate that the proposed framework can provide more accurate PQDs identification and meet the real-time response requirements in engineering practice.关键词
