引言随着智能配电网建设的不断推进,IEC60870-104通信规约的应用已从输电网向配电网拓展。在通信协议领域,由于协议本是用自然语言描述的,存在二义性,从而使得协议实现者对于协议的不同理解(微弱的差异)产生不同的协议实现,甚至出现错误[1];而不同厂家的终端设备在通信协议格式存在较大差异,也将导致各设备间的通信存在诸多障碍。因此迫切需要好的设计方法和工具帮助开发者设计一套适用IEC60870-101/104通讯协议在智能配电网应用时的智能化自动测试系统,用以保证在互换设备后,整个系统通信仍具有可靠性、
INTRODUCTION With the continuous development of smart distribution network construction, the application of IEC60870-104 communication protocol has been expanded from transmission network to distribution network. In the field of communication protocol, since the protocol is described in natural language, there is ambiguity, which makes protocol implementers have different protocol implementations and even errors [2] for different understandings (weak differences) of protocols Manufacturers of terminal equipment in the communication protocol format, there is a big difference, will also lead to communication between the various devices there are many obstacles. Therefore, there is an urgent need for good design methods and tools to help developers design a set of intelligent automatic test system for IEC60870-101 / 104 communication protocol in smart distribution network to ensure that after the exchange of equipment, the entire system communication With reliability,
