最近正在学习IEC61850, 初步的学习后有了一些体会,将其写下来, 希望能有感兴趣的朋友一起交流.

IEC61850标准-变电站通讯网络和系统,是新一代的变电站通讯体系,着力于解决变电站内部的不同厂家之间的互操作性,信息共享等问题.

IEC61850标准常常伴随着数字化变电站这一名词出现,这主要是区别于常规的变电站通讯而言的.但是同时要注意,对于全数字化的变电站,单是二次设备符合IEC61850国际规约，还不是真正的数字化，我们还要看是不是完全实现了信号的数字化采集和传输，对于一次主设备，如开关、变压器等，有没有实现数字化监测.

言归正传,谈谈IEC61850标准本身.

IEC61850由IEC标准化委员会制定, 主要应用到变电站自动化系统(SAS).它定义了变电站内的各种智能电子装置(IED)之间的通讯标准以及相关的系统要求. 在IEC61850-变电站通讯网络和系统这个大标题下,包含以下这些部分:

Part 1: Introduction and overview (IEC61850-1)

Part 2: Glossary (IEC61850-2)

Part 3: General requirements (IEC61850-3)

Part 4: System and project management (IEC61850-4)

Part 5: Communication requirements for functions and device models (IEC61850-5)

Part 6: Configuration description language for communication in electrical substations related to IEDs (IEC61850-6)

Part 7-1: Basic communication structure for substation and feeder equipment – Principles and models (IEC61850-7-1)

Part 7-2: Basic communication structure for substation and feeder equipment – Abstract communication service interface (ACSI) (IEC61850-7-2)

Part 7-3: Basic communication structure for substation and feeder equipment – Common data classes (IEC61850-7-3)

Part 7-4: Basic communication structure for substation and feeder equipment – Compatible logical node classes and data classes (IEC61850-7-4)

Part 8-1: Specific communication service mapping (SCSM) – Mappings to MMS (ISO/IEC 9506-1 and ISO/IEC 9506-2) and to ISO/IEC 8802-3 (IEC61850-8-1)

Part 9-1: Specific communication service mapping (SCSM) – Sampled values over serial unidirectional multidrop point to point link (IEC61850-9-1)

Part 9-2: Specific communication service mapping (SCSM) – Sampled values over ISO/IEC 8802-3 (IEC61850-9-2)

Part 10: Conformance testing (IEC61850-10)
