【摘要】：智能电网是电力工业未来的发展方向，在智能电网建设的推动下，未来数字化变电站将成为新建变电站的主流。中国持续强劲增长的国民经济以及我国电网面临的独特需求造就了中国电力市场环境的特殊性，并给中国电力企业带来了新的挑战。IEC61850变电站通信网络和系统规约是国际电工委员会为了适应电力行业高速发展所带来的高效、共享互操作、工程集成等要求而制定的针对变电站内IED设备的网络通信的国际标准，也是实施变电站智能化的唯一指导性国际标准。构建一个符合智能变电站性能要求和功能要求的通信网络系统，是建设智能变电站的前提，，这一工作涉及变电站特定的通信协议栈的开发、网络设备、组网方案、通信性能分析等工作。本文以天津千米桥220kV智能变电站为实例，分析了采用IEC61850规范，设计智能化变电站通信网络系统的结构特点，以及智能化变电站建模、组网规则等工作。结合三种通信组网传输方式（MMS、GOOSE、SMV）实现的异同，讨论了其在实际工程中应用的相关要求及实现机制，并具体负责构建了该站的MMS网。MMS网主要用于间隔层设备与站控层设备之间的通讯，反应变电站的基本信息和定值服务功能，为变电站的稳定运行提供技术保证。
[Abstract]:Smart grid is the future development direction of power industry. Under the impetus of smart grid construction, digital substation will become the mainstream of new substation in the future. The sustained and strong growth of China's national economy and the unique demand faced by China's power grid have created the particularity of China's electricity market environment. It also brings new challenges to Chinese electric power enterprises. IEC 61850 substation communication network and system protocol is an efficient and shared interoperation brought by the International Electrotechnical Commission in order to adapt to the rapid development of the power industry. The international standard for network communication of IED equipment in substation, which is formulated by engineering integration and other requirements, is also the only guiding international standard for the implementation of substation intelligence. The construction of a communication network system that meets the performance and functional requirements of intelligent substation is the premise of the construction of intelligent substation. This work involves the development of substation specific communication protocol stack, network equipment, networking scheme. Communication performance analysis and other work. Taking Tianjin Qianmiqiao 220kV intelligent substation as an example, this paper analyzes the structural characteristics of designing intelligent substation communication network system by using IEC61850 specification, as well as intelligent substation modeling, networking rules and so on. Combined with the similarities and differences of the implementation of three communication networking transmission modes (MMS,GOOSE,SMV), the related requirements and implementation mechanism of their application in practical engineering are discussed. The MMS network is mainly used for the communication between the spacer equipment and the station control layer equipment, which reflects the basic information and fixed value service function of the substation, and provides the technical guarantee for the stable operation of the substation.
