Electric power data storage system based on block chain

Abstract

The invention discloses an electric power data storage system based on a block chain, and belongs to the technical field of electric power data storage. Theelectric power data storage system comprises an electric power data acquisition module, a wireless transmission module, a cloud processing platform, an electric power supervision department, a plurality of substations, a plurality of electric power management companies and a plurality of substation storage nodes. Compared with a traditional centralized cloud storage system, the centralized cloud storage system is provided with the cloud processing platform, the cloud processing platform does not have a storage function, the electric power data are sliced and encrypted by adopting a block chain technology, and finally the electric power data are distributed to each substation storage node for distributed storage, so that the electric power data are prevented from being maliciously tampered, and even if the system is attacked to cause data leakage, lawbreakers cannot obtain complete power data, so that the storage security of the power data is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of power data storage, in particular to a blockchain-based power data storage system. Background technique [0002] After retrieval, Chinese Patent No. CN109936594A discloses a cloud storage system based on electric power data. Although this invention has the advantages of ensuring data consistency, ensuring stable operation of the system and reducing management difficulty, it is a centralized storage method and is easily attacked. Attacks and tampering cannot effectively guarantee the storage security of power data; blockchain is a technical means in the field of information processing. In essence, it is a shared database. The data or information stored in it has "unforgeable ", "retaining traces throughout the process", "openness and transparency", "collective maintenance" and "decentralization", based on these characteristics, blockchain technology has laid a solid "trust foundation" and created a...

[0002] After retrieval, Chinese Patent No. CN109936594A discloses a cloud storage system based on electric power data. Although this invention has the advantages of ensuring data consistency, ensuring stable operation of the system and reducing management difficulty, it is a centralized storage method and is easily attacked. Attacks and tampering cannot effectively guarantee the storage security of power data; blockchain is a technical means in the field of information processing. In essence, it is a shared database. The data or information stored in it has "unforgeable ", "retaining traces throughout the process", "openness and transparency", "collective maintenance" and "decentralization", based on these characteristics, blockchain technology has laid a solid "trust foundation" and created a reliable "cooperation mechanism ", so it has a wide application space; power data is the basic energy privacy data of the country, and its security status is an important guarantee for the healthy, stable and sustainable development of the national economy; , to promote economic and social development; on the other hand, data fusion across disciplines, units, and departments within electric power companies can improve industry and enterprise management levels and economic benefits; therefore, how to ensure the safety of power data storage and the scientificity of scheduling , has become one of the main bottlenecks in the development of smart grids. At present, most of the power data are stored in a centralized way, and their data is stored in the cloud data center, which is easy to be attacked and tampered with; therefore, a blockchain-based power data is invented. Storage systems become particularly important;

[0003] Most of the existing power data storage systems use centralized cloud storage for power data storage. Although it can effectively alleviate the data storage pressure of power companies, it is vulnerable to attacks and tampering, and cannot effectively guarantee the storage security of power data; To this end, we propose a blockchain-based electricity data storage system
