As the most widely used standard of intelligent substation communication,IEC 61850 satisfies the quite high requirement in real-time and reliable communications,but it does not define the specific communication protocol,which causes difficulties such as variation of mapping and non-standardization. Based on the existing problems of MMS and high coupling model of client / server communication issues during the mapping process. This paper proposes a new view,which is data distributions service applied in the distributed communication system to replace manufacture message specification( MMS) as application layer protocol. Data distribution service( DDS) adopts data-center publish-subscribe communications model,and overcomes the problems about height coupling model between server and client; P / S model also provides the support of Qo S and improves the flexibility of communication. Meanwhile,DDS defines global data space,provides a simple and intuitive way to transfer data,and further to meet the requirements of real-time systems.
