【摘要】 IEC 61850 对于具有严格时序要求的控制类操作采用“状态机”来定义其通讯服务。“状态机”技术的基础是计算机科学的经典理论——“自动机理论”,被广泛应用于网络通讯、语言翻译、行为识别等方面,但被引入到变电站通讯标准却是首次。这种技术应用于 IEC61850 也表明,“互操作性”目标需要更加深入的计算机科学理论和技术的支持。作者以 IEC61850“互操作性”为主题,介绍“自动机理论”的基本原理,探讨它在该标准中的应用价值,以挖掘计算机科学理论及技术在 IEC61850 中的应用深度。更多还原

【Abstract】 In IEC 61850 the communication services of the controlling operations with strict sequence requirement were defined by state machines. The classical theory of computer science, namely the automata theory, was the technical basis of state machine and widely used to such aspects as network communication, language translation and behavior recognition, but it was the first time for this theory to be led into the substation communication standard. Such an application to IEC 61850 indicated that for interoperability the powerful support from the theory and technology of computer science was necessary. Focused on the subject of IEC 61850’s interoperability, the basic principle of automata theory was presented and the value of applying this theory to IEC 61850 was discussed to excavate the application of computer science and technology in IEC 61850.更多还原
