At 18:15 on August 13th, Ms. Li, who lives in Xinhe Garden, Changzhou City, Jiangsu Province, suddenly had a power outage and resumed power supply after one minute.In this minute, Jiangsu Electric Power Co., Ltd. realized a 10 kV substation fault resection isolation and automatic load switching by computer, which limited the negative impact of fault blackout at the fastest speed.This is due to the company's new generation of distribution automation master station system that was put into operation in Changzhou on July 31.

  The new generation of distribution automation master station system has realized real-time data processing from one million to ten million, from a single I zone acquisition to multi-zone, multi-source data collection, from centralized application services to massive data. Technical breakthroughs such as platform service architecture have met the dual business needs of distribution network operation monitoring and state control.The system I area has the functions of distributed power access control, distribution network simulation training and large-area power outage processing, which can improve the dispatching department's ability to support the distribution network operation management level and emergency response, and meet the regional distributed power supply, micro-grid, Energy storage and other construction and development needs; District IV has "two remote" terminal data access, distribution network single-phase ground fault analysis, distribution terminal management, line and equipment heavy overload analysis, distribution network line loss analysis and other functions, expanded Practicality, meeting the needs of the distribution network inspection business.

  According to Qian Bo, director of the Transportation Inspection Department of Changzhou Power Introduces, the new generation of distribution automation master station system is like installing the "clairvoyance" and "Nerve Center" for the distribution network.Through timely big data collection and analysis, it can make the distribution network be monitored in real time like the main network. Whether it is daily operation monitoring, scheduling operation or fault handling, it can quickly and accurately switch the grid operation mode and isolate the fault power outage area. , comprehensively improve the reliability of power supply.It is reported that in the next step, State Grid Jiangsu Power will comprehensively promote the construction of a new generation power distribution main station system for power supply companies across the province.
