Distribution substation terminal with positioning function and positioning implementation method therefor

Abstract

The invention discloses a distribution substation terminal with a positioning function and a positioning implementation method therefor. The distribution substation terminal comprises a distribution substation terminal body (1) which is provided with a communication module (2). The communication module (2) comprises a wireless module (3) supporting multi-standard networks and a positioning module (4) supporting multiple positioning systems and capable of starting the multiple positioning systems at the same time. The positioning module (4) and the wireless module (3) are electrically connected with each other, and longitudinal information and latitudinal information is sent to the main station of the distribution substation terminal body (1) for positioning via the wireless module (3). The invention is advantaged by few positioning restriction and small positioning error probability.

Description

technical field [0001] The invention relates to a power distribution and transformation terminal with a positioning function and a positioning realization method thereof. Background technique [0002] The intelligent distribution transformer terminal is a device that collects operating information such as distribution transformers, incoming and outgoing line switches, residual current action protectors, and smart energy meters, as well as user electricity consumption information. Functions such as protector monitoring, status monitoring, load management, dynamic reactive power compensation / three-phase unbalance control / harmonic control, security protection, interactive management, asset management, video surveillance, environmental monitoring, and distributed power access management. [0003] The current intelligent distribution transformer terminal does not have a positioning function. In the monitoring system of the main station, the staff of the station area fill in the g...

AI Technical Summary

Problems solved by technology

[0003] The current smart distribution transformer terminal does not have a positioning function. The staff in the station area fill in the geographic location file of the terminal according to the general location of the terminal when it is installed in the monitoring system of the main station. The accuracy of this location is relatively low.

When there is a problem with the terminal, the staff in the main station area needs to go to the site to find and analyze the problem in person. Since the terminal cannot be located, if the staff in the main station area is not familiar with the specific installation location, it will take a lot of time to search Geographical location of terminal installation

This will not only waste the time of the staff in the main station area, but also reduce the work efficiency.

[0004] In view of the above situation, the patent document with the announcement number CN 102915626 A discloses a remote meter reading system and its concentrator and timing method. The GPS module is installed in the center to realize the positioning of the concentrator, but the system can only rely on the GPS module to achieve positioning, which is subject to relatively large limitations, and cannot provide more accurate positioning for the terminal, which is not conducive to the repair work of the staff in the main station area
