基于扩展103规约的保护装置通信与调试系统设计

Design of communication and debugging system for protection device based on extended 103 protocol

针对日益复杂的保护装置和受限的装置人机接口,提出并实现了一种基于扩展IEC60870-5-103规约的保护装置通信与调试系统。该系统以IEC60870-5-103规约为基础,并对其进行扩展,除了具有IEC60870-5-103规约的全部功能外,还支持装置菜单读取、权限控制、装置命令执行等功能,有效地弥补了装置面板人机交互功能差、IEC60870-5-103规约无菜单结构、无权限控制和无法支持装置全部接口功能的局限性。经过在保护装置中的实际工程应用,表明本系统通信稳定可靠,调试功能全面丰富,支持了装置所有的接口功能,提高了保护装置的开发和调试效率。

To settle the ever profound protection device and its limited human-machine interface, this paper promotes and implements a communication and debugging system extended from the IEC60870-5-103 protocol. The system extends IEC60870-5-103 protocol by supporting device menu reading, access control, device command execution and other functions besides its pre-existing functionality, which makes up the protocol＇s limitations such as weaker human-machine interface of device panel, lacking of menu structure and access control, and incomplete supporting of all interface functions, etc. Engineering application in protection devices demonstrates the system has high communication stability and comprehensive debugging functions, as well as supports all interface functions of the device, thus effectively increases the development and debugging efficiency for protection device.
