Embodiment

[0075] figure 1 The functional framework of the large power grid panoramic security defense system based on big data technology is mainly designed. The main functional process is as follows:

[0076] (1) The physical layer includes the actual power grid structure and the external environment related to the power grid. The present invention first collects the power grid information and external environment information on the physical layer, and realizes the collection and preprocessing of the information, so as to realize the security defense system of the power grid in the future Provide a data base.

[0077] (2) The transport layer is mainly responsible for the storage and transmission of information, and transmits the processed and screened information to the computing layer to provide basic data services for the computing layer.

[0078] (3) The calculation layer mainly utilizes the big data technology provided by the present invention to perform big data analysis and calc...

Abstract

The invention provides a large power grid panoramic security defense method and system. The system comprises a physical layer, a transmission layer, a calculation layer and a presenting layer; the defense system fuses and transmits acquired periodical power grid data, and analyzes and stores transmission data to conduct data mining on power grid data; according to data mining of the power grid data, the power grid data after being processed is calculated through a big data technology, and a calculation result is presented. According to the large power grid panoramic security defend method and system, electrical space-time big data intelligent mining depth and utilization breadth are effectively expanded, and solid technical support is provided to achieve global energy Internet active defense.

Description

technical field [0001] The invention belongs to the field of online safety monitoring and early warning of a large power grid, and specifically relates to a method and system for panoramic security defense of a large power grid. Background technique [0002] Unbalanced distribution of energy, uncoordinated economic development, and prominent environmental issues. The future development model of energy will show the energy Internet with the deep integration of renewable new energy technology and information Internet technology, and realize efficient, safe, economical and flexible development of energy. At the same time, the Energy Internet will bring great opportunities and challenges to the development of electrotechnical disciplines, theoretical research and engineering applications. Under the high penetration rate of renewable energy and the rapid development trend of energy Internet, the power grid will also present more complex random, multi-source big data and multi-sca...
