摘　　要：针对电能质量分析仪量值溯源必须将设备送至专业机构才能完成,不仅耗时费力,而且不能在实际工况条件下评估设备计量性能的现状,研发了电能质量分析仪远程在线校准平台。该平台结合网络技术、测量技术和通信技术,利用物联网、云服务及加密技术建立了一套完整的远程校准流程,并实现了实时控制标准器和被校设备、自动采集和处理数据、自动生成校准证书等。通过该平台,用户在任何地点只需将标准器和被校设备开机并连接好数据线和网络,上级计量技术机构即可实现异地操作完成全部校准过程,并保证校准全过程的可控。实验测试表明,该远程在线校准平台的校准精度高、操作简便,具有广阔的应用前景。In response to the current limitations in calibrating power quality analyzers,which typically require sending equipment to professional institutions for metrological traceability—a process that is not only time-consuming and labor-intensive but also fails to evaluate measurement performance under actual operating conditions—we have developed a remote online calibration platform for power quality analyzers.This innovative platform integrates network technology,measurement technology,and communication technology,leveraging the Internet of Things,cloud services,and encryption techniques to establish a comprehensive remote calibration process.The system enables real-time control of standard instruments and devices under calibration,facilitates automatic data collection and processing,and generates calibration certificates autonomously.With this platform,users anywhere can simply power on the standard instrument and the device under calibration,connect the necessary data cables and network,allowing superior metrological technical institutions to remotely conduct the entire calibration process,ensuring full control and oversight throughout.Experimental tests have demonstrated that this remote online calibration platform offers high calibration accuracy and userfriendly operation,presenting broad application prospects in the field of power quality measurement and smart grid technologies.
