Front-end terminal detection platform for power distribution

Abstract

The invention, which belongs to the technical field of smart grid, provides a front-end terminal detection platform for power distribution. The detection platform comprises a power distribution workstation, an intelligent controller, a communication area and a printing area. The power distribution workstation is used for displaying real-time data information of a main station synchronously to enable the field detection staff to carry out point countering with a remote main station visually and conveniently, and storing detection data timely to realize after-event query or printing. The intelligent controller is able to control a relay protection and transformer characteristic test module and is used for implementing detection processes of current and voltage telemetering testing, protection action remote signaling testing, and mutual inductor transformer ratio testing and the like, realizing a one-key sequential control mode, and storing detection data timely for after-event query or printing. An ONU is stored in the communication area to complete information interaction work between the main station and the workstation. The printing area is used for completing printing work of detection documents stored in the power distribution workstation and the intelligent controller. With the front-end terminal detection platform, the safety is improved and the detection efficiency is enhanced.

Description

technical field [0001] The invention belongs to the technical field of smart grids and relates to a front-end terminal detection platform for power distribution. Background technique [0002] In the process of distribution automation construction, there are a lot of basic detection work to ensure that the distribution network equipment is remote, accurate and real-time observable, measurable and controllable. Due to the limitation of fiber optic channel, the current detection work mainly adopts the mode of "single detection in equipment area + joint debugging of on-site installation". The single inspection work in the equipment area is mainly a series of indoor routine inspections separated from the main station, while the functional joint debugging inspection of the power distribution automation system under the monitoring of the main station can only be carried out on site. At present, there are many types of detection items in the equipment area, each signal needs to be ...

AI Technical Summary

Problems solved by technology

On-site joint debugging is easily affected by the external environment, such as weather, power supply, traffic and terrain conditions, etc.

According to actual statistics, the average detection time for one terminal device is 85.7 minutes, requiring at least 6 people to cooperate on site, and a line often involves multiple terminals, and it takes a long time to detect one by one, and sometimes the detection process is not smooth, especially When encountering uncertain factors such as "stuck" or finding "sickness" of newly installed equipment, the power outage time of the line will be greatly extended

[0007] 2. The detection task of power distribution terminal is heavy

All instruments and switchgear need to be energized separately with the power cord. The test instruments need to be connected to the ground grid with the ground wire, and network cables and aviation plug-in wires are also required to connect the equipment. However, the number of terminals and switches involved in the power distribution automation project There are many, and the testing equipment is scattered and independent, and the integration degree is not high. With the streamlining of equipment testing operations, various lines on site in the equipment area are easy to be complicated, which brings inconvenience to the on-site testing personnel

[0009] 3. It is difficult to guarantee the quality and efficiency of the point-to-point inspection process

The distribution automation system is characterized by a large number of equipment and a wide geographical coverage. The distribution automation terminal and primary equipment cover the entire urban area. Most of the installation locations are near roads and streets. There are many uncontrollable factors and dangers, which increase the labor cost of on-site inspection. , often inefficient
