【摘要】：随着电网技术的飞速发展，智能电网的概念被提出，而为满足信息化、互动化、自动化的要求，智能变电站应运而生。作为国家全面建设智能电网的核心工作，智能变电站建设是智能电网建设整体框架中提升电网智能化水平的重中之重，为变电站设备的高效可靠运行、监控和维护搭建现代化平台，实现了变电站设备管理模式的重大突破。新一代智能变电站与数字化变电站的全站组网技术不同的是，智能变电站的网络通信结构采用点对点通信。按新一代智能变电站设计要求，变电站自动化系统采用开放式分层分布式系统，按照“三层一网”设计，MMS/GOOSE/SV“三网合一”，，通信规约统一采用DL/T860通信标准。就地线路保护“直采直跳”；主变保护采用“直采直跳”；站域保护采用“网采网跳”。本文以新城市110kV变电站为实例，主要分别就电力系统一次、电力系统二次，通信、电源、节能、环保措施进行全面分析及可行性、技术创新研究，为智能变电站的技术发展提供了很好的技术参考。
[Abstract]:With the rapid development of power grid technology, the concept of smart grid has been put forward. In order to meet the requirements of information, interaction and automation, intelligent substation came into being. As the core work of the national comprehensive construction of smart grid, the construction of intelligent substation is the most important part in the overall framework of smart grid construction to improve the intelligence level of power grid, which is for the efficient and reliable operation of substation equipment. Monitoring and maintenance to build a modern platform to achieve a major breakthrough in substation equipment management mode. The new generation of intelligent substation is different from the whole station networking technology of digital substation, the network communication structure of intelligent substation adopts point-to-point communication. According to the requirements of the new generation intelligent substation design, the substation automation system adopts an open hierarchical distributed system. According to the design of "three layers and one network", the communication protocol adopts DL/T860 communication standard. In-situ line protection "straight jump", main transformer protection "straight mining straight jump" and station area protection "net mining jump". This paper takes the new city 110kV substation as the example, mainly carries on the comprehensive analysis and the feasibility, the technical innovation research on the power system primary, the power system secondary, the communication, the power supply, the energy saving, the environmental protection measure respectively. It provides a good technical reference for the technical development of intelligent substation.
