摘　　要：针对当前智能变电站中的继电保护装置在运维业务配置中存在效率低、设备运行故障诊断定位不够准确的问题,提出一种面向继电保护运维业务的继电保护数字孪生建模技术并进行应用探索。该技术通过分析继电保护运维业务需求,从运维业务、物理空间、信息物理融合这三个维度构建面向继电保护运维的数字孪生模型,实现继电保护业务能力、图形能力的自发现、自描述,支撑继电保护运维系统对继电保护装置的快速接入与配置、设备运行故障快速定位的功能,使继电保护运维业务接入和配置的效率提高90%以上,设备故障定位也可精准到插件级别。A digital twin modeling technology for relay protection is proposed and applied to explore the problems of low efficiency and inaccurate equipment operation fault diagnosis and positioning in the operation and maintenance business configuration of relay protection devices in current smart substation.This technology analyzes the requirements of relay protection operation and maintenance business,and constructs a digital twin model for relay protection operation and maintenance from three dimensions:operation and maintenance business,physical space,and information physical integration.It realizes self-discovery and self-description of relay protection business capabilities and graphical capabilities,and supports the rapid access and configuration of relay protection devices and equipment operation fault location functions of the relay protection operation and maintenance system.The efficiency of accessing and configuring relay protection operation and maintenance services is improved by more than 90%,and equipment fault localization can also be precise to the plug-in level.
