摘要
随着数字化变电站的快速发展,IEC 61850在数字化变电站中得到广泛应用。高压直流输电(HVDC)工程的建设也十分迅速,但换流站的数字化水平还远低于变电站,主要体现在传输规约和传输网络等方面。文中结合天广直流改造工程,从装置建模和站控层通信冗余处理两个方面来阐述IEC 61850在直流输电系统中的应用。随著数字化水平要求的提高,IEC 61850也将是HVDC系统自动化技术发展的重要基石。
With rapid development of digital substation, IEC 61850 can be widely used. HVDC projects are also in quick developing process, but the digital level of converter station is much lower than substation, mainly reflecting in transmission protocols and transmission network etc. Based on the reconstruction of Tian-Guang HVDC project, this paper illustrated the application of IEC 61850 in the HVDC system from two main sides： device modeling and station-layer communication redundant processing. With the improvement of digital level, IEC 61850 will also be an important cornerstone for the development of automation technology in HVDC systems.
