Digitalization -is to install "Thousand Mile Eyes" for the matching network, and to regulate the "compass"

State Grid's Power Supply Company of Jiu Tai District, Changchun City, Changchun City, thoroughly implemented the spirit of the company's two sessions, focused on digital empowerment, vigorously implemented digital transformation and development, conforming to the era of comprehensive digitalization, followed the company's digital transformation general planning guidelines, and efficiently utilized the network map mold system system Global perception search positioning, comparison scheduling system pavement voltage, monitoring current and load change curve, analysis of the abnormal and judgment of diagraming voltage abnormalities, etc., quickly and accurately locate the fault lines and scope, issue inspection and repair orders at the first time, change the "passive repair" In order to "actively serve", solve the problem of blind adjustment of the county branches of the county for many years, and greatly enhance the ability of the faulty sensing and dispatching of the distribution network.

Data empowerment management and control upgrade

Seize the new situation of digital transformation, promote the digital transformation of enterprises to a new level, improve the reliability and power supply quality of the distribution network. Based on the management of power outages and leaning, it is consistent, complete, easy to operate, and economical. The four -step method of governing the foundation, refinement, management, and sharing "deepen the application of the network graph model system, realize the" panoramic "operation monitoring," precision "research and judgment alarm," active "operation and maintenance," intelligent " "Statistical analysis, integrate the application of" legal integration "intelligent inspection and multi -data platforms to help distribution network management and control upgrade.

Data support panoramic perception

Practice -combination of figures, matching, and panoramic monitoring.

A verifying basic data of all power stations, lines, changes, and households in the county area, control the quality of the data source, apply the "connected to the orbit" method to match the matching, and use the "traceable source source" method to track the change switch to perform the drawing and the topology of graphic drawing and topology Check, integrate integrated isolation device, far -pass fault indicator, one or two fusion switches, ring network cabinets, opening and closing locations and other state monitoring, to achieve accurate research and judgment, accurate positioning, and accurate command. During the application process, problems were found and solved in a timely manner, and closed -loop control of the newly changed process is closed, and continuous optimization measures consolidated the results.

Application -real -time perception, accurate research and judgment, and command for repair.

"Warning! Xinglong changed 10 kV Xingchun Line 109 to switch the downstream area of ​​many households to run. It is suspected to be a card or disconnected, please arrange personnel to go to the scene to verify!" After getting the fault information, the panoramic monitoring and positioning of the network graph model system, the bus voltage of the D500 system's bus, the combined line current and the load change, the analysis of real -time call test results, etc. From the failure to the positioning of the positioning fault command, to the reporting of the power outage information group, the whole process only took 15 minutes.

The fault disposal realizes the "three precision research and judgment". Precisely judge a single configuration failure, and automatically pop up the power outage and recovery information of the faulty distribution through the "distribution network remote letter change position" module; precisely judge the switching of the card or disconnecting failure, focusing on the suspension of two or more matching of two or above. The changing line switch is traced on the power supply, combined with the web line topology structure to accurately position the card or disconnect switch; precisely judge the voltage abnormal failure, comprehensively analyze the failure of the voltage abnormalities, the line load changes, and the imbalance of the matching voltage of the time, lock the lock -up Failure range.

Management -consolidation foundation, homologous maintenance, closed -loop management and control.

Strengthen organizational leadership, strengthen work overall planning, establish a flexible management team, build a data governance structure system, pay attention to the "four levels" of the source data, data review, data monitoring, and data analysis. "Side pollution and edge governance", enhance the distribution system, marketing basic data, and PMS distribution information through the consistency rate, form a unified data model of "clean data clean and transparent, unified model specifications, verify flexible intelligence" Zhang Tu "" Data Source "and" Business Line ", which improves business collaboration and data synergy in various professional departments, and create a good digital ecology.

Maintain the "dynamic tree". The first step "foundation foundation" adheres to the principle of "not changing the map, not accepting, non -stop power", eliminating offline changes, and ensuring the timeliness and accuracy of the differential flow of the network diagram. The second step is to "cut the trunk". The grass -roots power supply center must apply for equipment changes online to uniformly report the equipment number and modified drawings in the graph model, and the relevant management departments will be maintained uniformly after approval. The third step "branches", continuously adding new motion updates in school nuclear, strengthen the timely and closed -loop control of the device's change process, and maintain the results of the application.

Services -data -driven, work order supervision, active service.

"It's amazing, I haven't reported it yet, you will come so soon!" The distribution network repair personnel received the low -voltage failure research work order from the power supply service command platform to quickly dispatch the customer's power failure, and the "passive repair repair "In order to actively serve", the speed of fault repair and the satisfaction of electrical customers have increased significantly, and the "Lianxin Bridge" of power companies and electricity customers has been set up. As of now, the active repair work order increased by 26.56 % year -on -year, and the number of reporting orders dropped by 28.57 % year -on -year. The average failure time of the failure of the failure of the volume was 6.34 % year -on -year, and the customer satisfaction rate reached 99.87 %.

Data fusion distribution network transparent

"In the past, the scheduling command had no way to accurately locate the range of faults. It took a long time to study and judge. Now the application of the modeling system can monitor the operating status of the equipment in real time. By deepening the application of the distribution model system, the "blind adjustment" problem of the distribution network branch has been solved, and the distribution network scheduling "considerable, measured, controllable, and adjustable" is realized, and the automatic research and judgment of the distribution network fault is The fault disposal efficiency has been improved, the power index is obtained, the business environment is optimized, and through the transparent management of the entire link and the whole process, the distribution network repair work has really achieved "the truth and the truth", and the full -time maintenance work and the fault treatment are fully dealt with. Process digital control. In the next stage, the power supply company of Jiu Tai District of Changchun City, Changchun City, continued to promote digital repair applications, and organized the person in charge of the repair work of the power supply center to carry out face -to -face, point -to -point communication, learning, guidance, and further improve the standardization and standardization and dispatch command process. Time -effectiveness, give full play to the efficiency and safety of interactive repair, realize the active renovation of rapid compound power, improve the quality of power supply, provide users with a reliable, stable, intimate and convenient power supply service, and provide reliable power guarantee for the high -quality and rapid development of the local economy.
