摘　　要：目前变电站二次回路设计交付仍然依赖于传统的图纸方式。这种方式需要具备专业知识的人员进行图纸校核和现场运维,不利于电力系统数字化技术的发展。为了实现对变电站二次回路接线的智能校验,本文借鉴了IEC61850逻辑建模思路,并提出了基于数字孪生的建模方案。本文从变电站工程设计的角度出发,对总平面布置、屏位布置、组屏方案以及关键的接线设计进行了数字化建模。在此基础上,结合工程经验将典型设计规范转化为数字化标准规则库,作为智能校核依据。通过对比匹配扫描站内屏柜、线缆二维码所获取的对象实例属性数据,我们实现了对设计成品的校核,并辅助施工及后期运维。通过某扩建工程模拟测试证明,采用该方法能够有效提升调试和运维人员的工作效率。Currently,the delivery of secondary curcuit designs in substations still relies on traditional drawing methods.This approach requires personnel with specialized knowledge for drawing verification and field operation and maintenance,which is not conducive to the development of digital technologies in power systems.To achieve intelligent verification of secondary circuit wiring in substations,this paper draws inspiration from the IEC61850 logical modeling approach and proposes a digital twin-based modeling scheme.Starting from the perspective of substation engineering design,the paper performs digital modeling of general layout,screen position arrangement,panel grouping scheme,and crucial wiring designs.Building on this,typical design specifications are transformed into a digital standard rule library,serving as the basis for intelligent verification.By comparing and matching object instance attribute data obtained from scanning on-site cabinet and cable QR codes,this method verifies the design product and aids in construction and later operation and maintenance.Simulation tests on a certain expansion project demonstrate that this method effectively improves the work efficiency of debugging and operation and maintenance personnel.
