State Grid Xinmi City Power Supply Company: Accelerate the construction of the self -healing demonstration zone of the new dense power distribution automation

Author:Henan Business Daily Time:2022.07.28

On July 27, the staff of the State Grid Xinmi City Power Supply Company was replacing the 10 kV Ledi 4 board Ⅰ Lexi Line 5#rod switch to one or two fusion smart switches, and the switch was connected to the power distribution automation system The wire line can be visually monitoring, which has completed the standardized wiring of the Ledi 4 board Ⅰ Lexi line, effectively isolation of branch faults, and providing preliminary support for the self -healing of the line. Essence

In order to further improve the reliability of power supply in the urban area, build a strong distribution network shelf, improve the ability to connect and provide interconnection, accelerate the installation of the end -to -end coverage, realize the self -healing function of power distribution, improve the level of use of self -use, and supply the level of use. Under the guidance of the Watching Department, the State Grid Xinmi Power Supply Company In accordance with the working principle of "unified planning, unified standards, and unified construction", combined with important customer distribution, geographical area division and regional network frame conditions, the "east to Changle Road, Changle Road east, The area of ​​about 2.4 square kilometers from the west to the future Avenue, the south to the west section of the west street to the north to the west street is used as a new densely power distribution self -healing demonstration area to comprehensively promote the construction of smart distribution networks.

The demonstration project of the self -healing center of power distribution automation is based on distribution automation, focusing on the self -healing control system, starting from the technical and management level, paying attention to practicality, and carrying out a detailed overall planning for 8 lines in the construction area. With the work idea of ​​"creating a standard model and establishing effective contact", carry out the planning of the network shelf and the planning of incremental mesh, in accordance with the standard of "handle hand in hand, three -point multi -link" in the air line Section transformation, while the load is reasonable, the original radiation line is constructed into a multi -segment moderate connection mode. At the same time, the installation and debugging of the fusion equipment such as DTU and FTUs, and the self -healing function of all distribution lines in the demonstration area in accordance with the centralized feedback line automation mode. Effectively realize the accurate positioning and automatic isolation of the fault of the distribution network, shorten the time of failure and power outage, and play a demonstration leading role for the construction of intelligent distribution networks in the new secret area.

As of July, State Grid Xinmi Power Supply Company has completed all line diagrams to organize and draw work, realizing 206 from the push, 43 reserves and contact projects, 4 approved power distribution automation projects, and the power distribution terminal transmission is launched 206 Taiwan, covering 190 lines. In the first half of this year, the use of power distribution automation system reduced the power outage of 1700. Households, and the average fault treatment time of the entire line was shortened by 12 minutes. Further strengthened the specialization and lean management of distribution networks, further improved the reliability and quality service level of power supply, and made a steady progress.

Next, the company used the self -healing demonstration area of ​​power distribution automation as a model, continued to promote the construction of the county's area power distribution automation, firmly guarded the security lifeline of the power grid, charged a beautiful life, and empowered the beautiful new secrets.
