摘要(Abstract):

随着传统电网向智能电网的发展,继电保护装置测试也由人工测试转向自动化测试。通过分析目前已有自动测试系统存在的不足,为了降低检测人力成本,提高继电保护的测试效率,提出了基于5G通信和图像识别技术的新型继电保护测试系统。系统采用模块化设计思路,利用5G网络连接云端服务器、自动测试平台和手机终端,从而实现客户端可下载测试方案,远程实时监控测试过程,快速获取测试报告。为了快速获取保护装置压板的状态,引入了图像识别技术,对测试方案的智能生成、虚端子自动配置等系统关键技术提出了相应的解决方案。目前,该系统已成功应用于500 kV萧围变电站和220 kV绿汀变电站的验收工作,测试效果理想。
As the traditional power grid has evolved into smart grid,testing of relay protection devices has shifted from manual mode to automatic model. By analyzing the shortcomings of the existing automatic testing systems,the paper proposes a new relay protection testing system based on 5G and image recognition technology to reduce labor cost and improve the testing efficiency of relay protection. The new system adopts a modular design idea and uses 5G network to connect the cloud server,automatic testing platform and mobile phone terminal so that testing solutions can be downloaded on the client,remote and real-time testing monitoring can be achieved,and testing report can be generated fast. In order to quickly obtain the pressure plate status of the protection device,image recognition technology is introduced,and corresponding solutions are proposed for the intelligent generation of test solutions,automatic configuration of virtual terminals and other key technologies. The system has been successfully applied to the acceptance of 500 kV Xiaowei substation and 220 kV Lyuting substation with satisfactory test results.
