摘要
智能电网是以智能一次设备和二次设备为基础,深度集合电力与通信技术而形成的未来电网体系结构。介绍了智能电网的发展及其技术内涵。针对智能电网保护控制系统的需求特点,指出同步测量技术为面向智能电网的保护控制系统提供了必要的技术基础,提出了基于广域信息的保护控制系统结构设计,并探讨了智能配电网保护控制面临的技术课题与研究思路。
It is the trend to investigate and implement smart grid in the 21st century. Based on the intelligent primary and secondary equipments, smart grid is the future power grid which integrates electrical and communication technologies closely. The paper introduces the development and technical content of smart grid firstly. According to the requirement of protection and control system of smart grid, the paper indicates that synchronized measurement technology provides necessary technical basis for protection and control, and proposes the structural design of integrated protection and control system based on widearea information. Lastly, the paper discusses the technical issues and research ideas for smart distribution grid.
