Power distribution network line fault on-line monitoring and positioning system and communication method

Abstract

The invention discloses a power distribution network line fault on-line monitoring and positioning system. The power distribution network line fault on-line monitoring and positioning system comprises a line fault indicator, a wireless acquisition device, a wireless ad hoc network and a monitoring main station, wherein the wireless acquisition device is in wireless communication with the monitoring main station through the wireless ad hoc network, the wireless ad hoc network comprises a central node and multiple sensing nodes. The central node and the multiple sensing nodes are connected in a wireless communication mode, and the multiple sensing nodes are connected in the wireless communication mode. The invention further discloses a communication method adopted by the power distribution network line fault on-line monitoring and positioning system. A networking method of the wireless ad hoc network comprises the following steps of initializing node electrification, starting to perform networking, finding neighbors and measuring field intensity, collecting the field intensity, performing route planning and configuration and performing normal work. By means of the system and the communication method, the power distribution network line fault on-line monitoring and positioning are performed, the networking can be performed quickly, a structure is flexible, data transmission is reliable, received data are complete, wireless communication signal dead zones do not exist, only one-time investment is required, operation expense is not required, and the operation cost is reduced.

Description

technical field [0001] The invention relates to a distribution network line fault monitoring and positioning system, in particular to an on-line monitoring and positioning system and a communication method for a distribution network line fault relying on a wireless ad hoc network. Background technique [0002] With the continuous development of the power system, there are more and more faults in the distribution line. In order to reduce the search workload after a line fault, shorten the fault repair time, save a lot of manpower and material resources, improve the reliability of power supply, reduce the loss of power failure, strengthen and improve the level of system operation and management, it is urgent to be able to quickly and efficiently after the system fails. Accurately find the fault point, the accurate location of the line fault point is becoming more and more important. [0003] Most of the traditional distribution network line fault monitoring and positioning sy...

Problems solved by technology

However, communication networks such as GSM or GPRS need communication base stations to achieve communication. In mountainous areas and other places that are far away from base stations or where large-scale communication base stations are not suitable, communication cannot be achieved, and there are communication blind spots.

At the same time, the operation of communication networks such as GSM or GPRS requires cost, because the distribution network line itself is a huge power network, so the communication cost is quite a lot, and its operating cost is high.
