Inter-District Collaborative Linkage and Multi-Source Data Fusion of Smart Substation

The forward security isolation device, reverse security isolation device, vertical encryption authentication device, encryption authentication measures, firewall and other security measures have been set up in each section of the substation. The efficiency of system data interaction across security zones is low and the interoperability is difficult. It is urgent to carry out the research on cross-zone business collaboration. In addition, each professional system of the substation is arranged independently and its application functions are separated, resulting in each professional system of the substation becoming an information island; the professional systems are diverse and the collected data are crossed, resulting in massive data and redundant information, which makes the management and control of substation data information more difficult, and information fusion is an effective way to solve the above problems.
