Method and system for establishing power grid visualized perceptual model

Abstract

The invention relates to a method and a system for establishing a power grid visualized perceptual model. The method comprises the following steps: firstly, performing situation awareness demand analysis according to the target of power grid security risk assessment, then sequentially performing data preprocessing and data integration according to the result of the situation awareness demand analysis, establishing a knowledge correlation analysis engine for data of environment factors and production factors, extracting the knowledge data to obtain statistically synthetic KPI data in a space dimension and a time dimension, adopting a visualization technology to visually show diagrams of the environment data, the statistically synthetic KPI data and the knowledge data, and combining the situation awareness with the visualized views to realize situation visualization, so as to establish the power grid visualized perceptual model. Through the model, the information of the various factors in the environment can be immediately acquired and acknowledged, the future state of the environment can be predicted, and the running state of the power grid can be shown in real time, so that users can understand and use the power grid knowledge more directly and quickly.

Description

technical field [0001] The invention relates to the technical field of smart grid operation security, in particular to a method and system for constructing a grid visualization perception model. Background technique [0002] Information visualization is the theory, method and technology of using computer graphics or image processing technology to convert information into graphics or images and display them on the computer screen for interaction. Visualization research on smart grid knowledge, on the one hand, can greatly reduce the difficulty and workload of developers, speed up the construction of grid visualization, and effectively solve the problem of "information islands" in power companies; on the other hand, it is more conducive to emergency response to emergencies When a sudden accident occurs in the power system, the staff can directly see the equipment status and the cause of the accident through the visually displayed data monitoring system, making the operation of...

Problems solved by technology

[0004] The present invention aims at the problems that the information visualization model commonly used in the current power grid makes the representation form of power grid knowledge visualization single and it is not convenient for the staff to understand the meaning expressed by the power grid knowledge visualization in a comprehensive and real-time manner, resulting in potential safety hazards in the operation of the power grid, etc., and provides a power grid The visual perception model construction method interacts situational awareness with visual views to realize situational visualization and form trending situational awareness indicators, so as to establish a corresponding power grid visual perception model, through which the information of various elements in the environment can be obtained and understood in a timely manner And predict the future state of the environment, and display the operating state of the power grid in real time, improve the level of power grid visualization, and realize users' more intuitive and rapid understanding and use of power grid knowledge
