The invention relates to an electric network structure vulnerability quantification and visualization display technology and discloses an electric network structure vulnerability real-time evaluation system for carrying out real-time evaluation and analysis on the electric network structure vulnerability. The electric network structure vulnerability real-time evaluation system has the technical scheme that the electric network structure vulnerability real-time evaluation system comprises a system management module, a data communication module, a vulnerability visualization module, an evaluation indicating module and a database module. The electric network structure vulnerability real-time evaluation system is based on the wide area measurement information, the electric network structure vulnerability is evaluated in real time, and the functions of the structure vulnerability evaluation, the real-time display, the real-time recording and the like of operation parameters in an electric network are realized. On one hand, the receiving of dynamic data transmitted by a WAMS (wide area measurement system) is realized, in addition, the dynamic structure and the state information are analyzed, and the real-time recording of the electric network operation state parameter is realized; and on the other hand, the electric network structure vulnerability evaluation and result display is realized, and basis is provided for improving the safe operation of the electric network.
