摘　　要：并入电网的光伏电站,对通信的可靠性和实时性有很高要求。IEC61850作为电力系统自动化领域唯一的全球通用标准,致力实现数字化变电站中不同厂商的设备之间的互操作,IEC61850标准只提供了抽象通信服务接口(abstract communication service interface,ACSI),没有定义具体的通讯协议的实现方法。提出引入(data distributions service)DDS规范来映射抽象通信服务接口的通信实现方案。根据IEC61850标准的信息模型和DDS规范的特点,设计出DDS规范与IEC61850标准中的抽象通信服务接口具体的映射方法,利用DDS规范基于发布/订阅的通信机制分发数据,同时利用DDS规范中的Qos策略,为光伏电站提供不同的实时性通信服务,以满足光伏电站的通信要求。The photovoltaic power station,which is merged into the grid,has a high demand for the reliability and realtime performance of the communication.IEC61850 as the field of power system automation the only global standard,is committed to realize digital substation in between different manufacturers of equipment interoperability and IEC61850 standard provides only the abstract communication service interface（Abstract communication service interface,ACSI）,no specific definition of communication protocol implementation method.In this paper,（data distributions service）DDS is proposed to map the communication implementation scheme of Abstract communication service interface.According to IEC61850 standard information model and DDS features,the mapping method of the abstract communication service interface in the DDS standard and the IEC61850 standard is designed,the use of DDS specification based on publish/subscribe communication mechanism to distribute data.At the same time,the Qos strategy is used in the DDS specification to provide different real-time communication services for the photovoltaic power station,to meet the needs of the photovoltaic power station communication requirements.
