Guiyang Power Supply Bureau plans to invest nearly 100 million yuan to build a smart distribution network project

Conduct visual monitoring of power supply equipment and line status; implement online data analysis of power load and power consumption of electricity users to ensure reliable power supply to users; use equipment fault location monitoring system to lock the fault point as soon as possible, ensure rapid power restoration, and minimize power outage time...The author learned from the Guiyang Power Supply Bureau of Guizhou Province, China Southern Power Grid, that in order to further help win the "two-front" people's war of "epidemic prevention and control and economic and social construction", the bureau has currently started the construction of 40 smart distribution network projects in the region to ensure their completion within the year.

Chen Pu, the director of the distribution network project management section of the project management center of the bureau, said in an interview that 40 new smart distribution network projects are concentrated in the three smart grid construction demonstration areas of Shuanglong, Wudang and Xifeng in Guiyang, with a planned investment of nearly 100 million yuan and more than 300 construction personnel. Different from ordinary distribution network projects, the investment cost of smart distribution network construction projects is slightly higher, mainly involving the construction of smart distribution stations including optical fiber composite quadrant OPMC cables, distribution rooms, switch stations, box transformers, and ring network switch cabinets; typical design of smart power supply areas including low-voltage user information monitoring, equipment and line status visualization monitoring, and smart distribution network scenario solutions including equipment fault location monitoring.

After the project was completed, the operation of the main power supply equipment in the smart distribution network was all monitored and controlled online, and the reliability of the power supply was further improved. When a fault occurred, the system quickly analyzed and found the fault, and the time for users to restore power was further shortened.
