Smart power grid information management system based on wireless sensor network

Abstract

The invention relates to a smart power grid information management system based on a wireless sensor network. An Internet of Things (IOT) architecture of a smart power grid information management platform comprises a smart power transmission module, a smart power transformation module, a smart power distribution module, and a smart power use model. A USN basic network model of the IOT is used and a USN architecture comprises, from bottom to top, five network architecture layers including an awareness network, an access network, a network basic facility, a middleware, and an application platform. The wireless sensor network is used in online monitoring of a high-voltage transmission line, primary and secondary equipment of a transformer station, and especially the primary equipment, distribution network automation, and power using information acquisition power grid requirement side communication. The IOT is effectively and reasonably combined with a smart power grid so as to construct the smart power grid information management platform. The smart power grid information management system improves informatization and automation level of a power system production link, and satisfies a real requirement of the smart power grid for high efficient economy, good safety and reliability, and social interaction.

Description

technical field [0001] The invention relates to a power grid information management system, in particular to a smart power grid information management system based on a wireless sensor network. Background technique [0002] In 1999, the Massachusetts Institute of Technology (MIT) first proposed the concept of the Internet of Things. Comprehensive perception, reliable transmission, and intelligent processing are the characteristics of the Internet of Things. See literature: BATALLA E. Recommendations for situational awareness [R]. Fort Lau-derdale, USA: RTBPTF, 2006. In order to eliminate data collection blind spots in the existing power communication network, clear information islands and many other problems, and realize a smart grid communication management platform with real-time monitoring and two-way interaction, it is necessary to organically combine the Internet of Things and the smart grid. How to integrate the environmental awareness of the Internet of Thin...

AI Technical Summary

Problems solved by technology

The defect of the traditional power grid is that there are a large number of blind spots in the terminal collection of data, and information sharing cannot be carried out within the system, resulting in partial and isolated information, and there are multiple information islands

When the amount of information collected is large, there are inconsistencies in the data, which reduces the usability and credibility, and the system cannot form an organic unified whole

Moreover, the level of information acquisition and utilization is low, and information management is fragmented and discrete. The modernization and intelligence of the entire power grid are not high enough to form comprehensive business applications.
