摘　　要：智能变电站是智能电网的重要环节,需要实时可靠的通信支持。IEC 61850作为智能变电站的通信标准,没有定义具体的通讯协议的实现方法,造成具体实现中面临映射多样化、非标准化以及实现复杂的问题。针对IEC 61850标准中的模型与常规的基于制造报文规范(manufacturing messagespecification,MMS)映射的不足,以及基于客户机/服务器结构的中间件的紧耦合问题,提出一种新型完全基于发布/订阅(publish/subscribe)方式的数据分发服务规范(data distributionsservice,DDS)映射抽象通信服务接口(abstract communicationservice interface,ACSI)的新方法。DDS提供丰富的服务质量策略,适合对实时数据要求高的应用环境。采用符合DDS规范的中间件作为映射实现的工具,设计了具体的映射实例模型,并针对电力工程应用特点,得出IEC 61850实现工程应用的标准步骤。相对于其他的软件中间件(如CORBA-TAO)映射的方法,基于DDS的中间件提供了一个简便、快速、规范的实现。最后设计实现智能变电站实时通信仿真系统,并测试验证了所提方法的实时可靠性。Smart substation is a key component of smart grid and requires real-time and reliable data communication.As a communication standard for smart substation,IEC 61850 has not defined details of how to implement special communication protocols,which causes difficulties such as variation of mapping,non-standardization and complexity of implementation.To remedy those mentioned shortcomings of IEC61850 model,defects of traditional manufacturing message specification（MMS） based mapping,and the closed coupling of client/server based middleware,this paper proposes a novel data distribution service（DDS） and fully publish/subscribe based methodology to implement the abstract communication service interface（ACSI） of the IEC61850.As DDS provides comprehensive Quality of Service（QoS）,it is suitable for applications with critical requirement of real-time data communication.The middleware that fulfills the DDS specifications is adopted as the mapping tool,and the real mapping model is designed in detail.Furthermore,according to the requirements of the power engineering,the standard implementation procedures of IEC 61850 are also obtained.Comparing with other types of middleware based mapping method,such as CORBA-TAO,the proposed DDS-based middleware can provide a simple,fast and standardized realization.Finally,a real-time communication simulation system for smart substation was set up to test real-time performance and reliability of the proposed method.
