摘要
介绍了国际电工委员会制定的基于TCP/IP网络的调度主站和远方子站远动通信协议-IEC60870-5-104的体系结构、参考模型、传输帧格式及在南方电网直调厂站中的应用。针对通过TCP/IP网络访问传输远动信息存在的安全问题,对其传输模式进行了深入研究,提出了一种基于加密和身份认证的安全报文传送方法。在南方电网应用的经验表明,该方法是合理和有效的。
General structure ,the network reference model, the frame format and the application of IEC60870-5-104 telecontrol protocol, which is published by IEC and used in the communication between the dispatching center and remote station based on TCP / IP network, are introduced in this paper. Aiming at the information security of remote transmission based on TCP / IP network access, the mode of transmission is in-depth studied. A practical method for packet transmission based on encryption and authentication is proposed. The application experience on China Southern Power Grid shows that the method is reasonable and effective.
