High voltage grid monitoring method and comprehensive monitoring system based on wireless sensor network

Abstract

The invention relates to a high voltage grid monitoring method and comprehensive monitoring system based on a wireless sensor network, aims at effectively monitoring the state information and the natural physical information of a piece of electric network equipment, and has the characteristics of being high in monitoring efficiency, low in monitoring cost as well as safe and reliable. The technical scheme is that: the high voltage grid monitoring method based on the wireless sensor network comprises the steps of: monitoring the high voltage grid by a plurality of wireless sensors positioned at various places in the high voltage grid, transmitting the measured information to sensor cluster heads and sink nodes in sequence, and transferring the measured information to a server and a plurality of remote client ends through an optical cable by Internet. The high voltage grid comprehensive monitoring system based on the wireless sensor network comprises a plurality of wireless sensor nodes positioned on the high voltage grid, the sink nodes for reception of information, the server for communicating a gateway with each sink node and the plurality of remote client ends, wherein a sensor cluster head for information transmission is arranged in each wireless sensor node, respectively.

Description

technical field [0001] The invention relates to a high-voltage transmission network monitoring method and a comprehensive monitoring system, in particular to a high-voltage transmission network monitoring method and a comprehensive monitoring system based on a wireless sensor network. Background technique [0002] The statistical results of our country from 1999 to 2008 show that not only the complex climate environment is one of the reasons for the large-scale power outage accidents of the power grid, but also the power grid accidents caused by the failure of the power transmission and transformation equipment itself have a tendency to increase year by year, accounting for about all power grid accidents every year. For example, in 2008, among the 57 accidents that had a great impact on the operation of the power grid, 29 were caused by power transmission and transformation equipment failures, accounting for about 51% of the total number of accidents. The analysis of the cau...
