摘　　要：继电保护设备的运行维护对远程调试和通信安全的要求日益提高。传统调试方式受限于现场操作且通信安全性不足,而虚拟专用网络(Virtual Private Network,VPN)加密通信技术为继电保护远程调试提供了高效可靠的技术解决方案。因此,设计一种基于VPN加密通信的继电保护远程调试方法,构建包括身份认证与权限控制、加密隧道的建立与管理、继电保护远程调试以及数据加密日志记录的完整技术框架。实验结果表明,该方法在调试响应、调试指令传输及数据完整性校验方面表现优越,在多数据量场景下具备良好的适应性,为继电保护远程调试提供了有力支持。The operation and maintenance of relay protection equipment requires more and more remote debugging and communication security.Traditional debugging methods are limited by on-site operation and lack of communication security.The encrypted communication technology of Virtual Private Network(VPN)provides an efficient and reliable technical solution for remote debugging of relay protection.Therefore,a remote debugging method of relay protection based on VPN encryption communication is designed,and a complete technical framework including encryption tunnel management,identity authentication authority control,remote debugging of relay protection and data encryption log recording is constructed.The experimental results show that this method is superior in debugging response,debugging instruction transmission and data integrity verification,and has good adaptability in multi-data scenarios,which provides strong support for remote debugging of relay protection.
