Electric network structure vulnerability real-time evaluation system

Abstract

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.

Description

technical field [0001] The invention relates to a technology for evaluating safe operation of a power system, in particular to a technology for quantifying and visually displaying the vulnerability of a grid structure. Background technique [0002] With the continuous advancement of the grid interconnection process, the scale of the grid is becoming larger and larger. The structure and operation mode of the large power grid are more complex, and the unforeseen factors increase, and the fragile characteristics of the power grid become more and more difficult to control. From the perspective of power grid dispatchers, how to grasp the global structural vulnerability of the large power grid, understand the actual operating status of the large power grid, formulate a correct dispatching model, and ensure the safe operation of the large power grid is an urgent need. Therefore, how to propose effective quantitative indicators of power grid structural vulnerability and visualize t...
