摘 要 :近年来,智能变电站保护设备检修并没有充分发挥智能站逻辑隔离和变电站过程层数据共享等优势,随着 IEC 61850 ED2 版本的发布,为继电保护装置远程在线测试提供了可行性。在遵循国际标准的前提下,提出了基于 IEC 61850 软报文的继电保护装置远程在线测试技术,通过继电保护装置虚回路软隔离,完成智能变电站检修状态下的继电保护装置的功能测试和回路校验。设计了基于该技术的智能变电站继电保护远程在线测试系统架构,以及从调度侧到智能变电站侧实现网络远程安全访问测试数据流程,并开发了基于容器技术的在线测试 APP,可灵活部署在变电站监控系统中。结合试点工程,充分验证了远程在线测试技术的安全性和可行性,显著提高了智能变电站继电保护装置的运维效率。

Abstract: In recent years, the advantages of smart stations such as logical isolation and process layer data sharing are not fully utilized in the maintenance of protection device in smart substation. With the release of the IEC 61850 ED2 version, it provides feasibility for remote online testing of relay protection devices. Under the premise of following international standards, this paper proposes a remote online testing technology for relay protection devices based on IEC 61850 message. Through virtual circuit soft isolation of relay protection devices, functional testing and circuit verification of relay protection devices in smart substations under maintenance conditions are accomplished. The architecture of the remote online testing system for relay protection in smart substation based on this technology was designed, as well as a secure remote network access process for test data from the dispatch side to the smart substation side was implemented, and an online testing APP based on container technology was developed, which can be flexibly deployed in the substation monitoring system. Combined with the pilot project, the safety and feasibility of the remote online testing technology are fully verified, which significantly improves the operation and maintenance efficiency of relay protection devices in smart substation.
Key words: smart substation; online testing system; virtual circuit soft isolation; IEC 61850
