The personnel on duty of the regulation and control team of the Gui'an Power Supply Bureau of China Southern Power Grid carefully monitor the operation of the power grid to ensure the safe and stable operation of the main network and distribution network
Young breeds vitality, dare to promote motivation. In Gui'an New District, Guizhou Province, there is a full bachelor degree or above, the average age is only 28 years old power dispatching operation team, very innovative, effective awareness, they rivet enough "brave to break the courage to stand, together to break the new road" of the momentum, the complex things are simplified, simple things process, repetitive things rules, in the western provinces and regions of the first research and development of customer service dispatching intelligent robot, in the Guizhou power grid jurisdiction to innovate the application of distribution network issuing system, the first to run the new main and integrated OCS dispatching automation system, the first to achieve" The integration of blending and control services is "practical operation.
This production team, which dares to fight and persistently climbs, is the Gui'an Power Supply Bureau Ground Regulation and Control Class of Guizhou Power Grid Company, which has been awarded the honor of "Five-star Station" of China Southern Power Grid, and it is also the only five-star team on the operation front of the entire Guizhou power grid system.
Strive to promote the "four unifications" and set the benchmark of "integration of deployment and control services"
The personnel on duty of the regulation and control team of the Gui'an Power Supply Bureau of China Southern Power Grid carefully perform their duties, act as good power grid operation commanders, and provide strong power guarantees for local economic and social development
As a regional power supply bureau with the management characteristics of "most of the office operation, flat management, one post multi-functional, one post and multiple responsibilities", the Gui'an Power Supply Bureau of China Southern Power Grid vigorously promotes the integration of deployment and control services, breaks down professional and departmental barriers, concentrates the distribution network emergency repair command and service dispatching business to the power dispatching and control center, implements the mechanism of "one mouth external, division of labor and cooperation, internal transfer and external transfer", and has achieved good results in management mode innovation, business process optimization, fine performance indicators, and streamlining of human resources. Customer satisfaction and market competitiveness have increased significantly.
At the beginning of 2018, in accordance with the idea of "unified platform, centralized business, step-by-step implementation, and optimization and integration", the regulation and control center was the core, and actively integrated the dispatching monitoring operation, distribution emergency repair command, service scheduling related services, and incorporated the intensive operation and maintenance of the distribution network and the customer manager system of the precinct into the integrated supporting construction of the deployment and control service. By optimizing and adjusting the operation mode of the dispatching system, strengthening the in-depth running-in between the regulation center and the service dispatching office, the Gui'an Power Supply Bureau's "integration of deployment and control services" was officially operated in more than half a year, creating a precedent for the practical operation of the "integration of deployment and control services" of the Guizhou power grid.
Focusing on the goal of "centralized regulation, main distribution coordination, operation and distribution linkage, and rapid response", the grid dispatching and control mode of Gui'an Power Supply Bureau has achieved "four unifications". In terms of unified scheduling, the control class breaks the traditional main distribution network scheduling separation barriers from the source, shortens the information communication and transmission time, coordinates to optimize the operation of the main distribution network, and efficiently handles the distribution network failure.
In terms of unified monitoring, the control class achieves remote messaging, telemetry, remote control "three remote" coverage of distribution automation terminals from the monitoring level, distribution and transformation TTU signal access, and remote retrieval of fault recording waves of Baoxin sub-station, effectively improving the efficiency of fault and abnormal disposal.
In terms of unified research and judgment, the regulation class integrates information such as customer reporting of obstacle work orders, protection action information, TTU dropout, distribution network DFA, fault indicator action situation, etc., and comprehensively studies and judges the failure of the distribution network, so as to respond quickly and accurately locate.
In terms of unified command, the regulation and control team comprehensively coordinates the operation, maintenance and accident disposal of the power grid, efficiently and uniformly commands the line operation and maintenance personnel to accurately find faults, the substation operation and maintenance personnel arrive at the substation operation site on time, and the account manager of the precinct finely serves the electricity customers.
Gui'an regulation and control class vigorously promotes the "four unifications", boldly integrates the work of the five teams of the traditional prefectural power supply bureau's ground adjustment main network dispatching class, local allocation network regulation class, ground adjustment monitoring class, customer service dispatching class, and distribution network emergency repair dispatching class, and comprehensively controls it, and sets up the benchmark of "integration of deployment and control services" of Guizhou power grid from the management and business. It is worth mentioning that the annual punctuality rate of Power Outage and Restoration of Gui'an Power Grid has reached 97.85%, the time of fault power outage has been reduced by 30% year by year, the transmission of power outage information is 0 time difference, and the streamlining rate of dispatching and operating personnel is as high as 38%, which injects strong impetus into accelerating the creation of domestic first-class power grid enterprises from the source.
Build service scheduling robots, work efficiency increased by 50%.
The regulators of the regulation and control class of the Gui'an Power Supply Bureau of China Southern Power Grid actively learn policy theories and professional and technical knowledge through mobile phones and tablet computers
Before July 2019, Guian Power Grid, for the dispatch and sales process of customer service work orders, the guian power supply bureau control class is checked through the work order SMS prompt and marketing system, and the full manual transmission is required, and the work order needs to be transmitted within the specified time limit, and the work order monitoring process needs to be manually recorded, and the work order processing time limit also needs manual monitoring, which is inefficient and the work content is highly repetitive, and the work process is very cumbersome. At the same time, because there is no special system to support the scheduling of marketing business services, the receipt and dispatch of work orders rely on manual notifications, and the lack of automatic reminder services for the disposal time of work orders, resulting in easy overdue disposal time; the implementation of monitoring after dispatch is also completed by manpower, and the overall quality is greatly affected by human factors.
It is imperative to transform and optimize the work order processing process, design a virtual robot for service scheduling of the prefectural power supply bureau, transform the previous manual delivery method into a process network submission, and establish an intelligent online work order processing platform.
Kung Fu pays off. After more than half a year of exploration and hard work, the technical research team of the regulation class of Gui'an Power Supply Bureau has focused on building a set of knowledge graphs with good scalability, strong compatibility, high level of intelligence, and integration of deployment and control services through modeling the data ontology knowledge of each business scenario of "allocation and control service"; at the same time, it has devoted itself to studying the natural language processing technology of power grid regulation business and the voice interaction service technology of power grid operation, researching and designing a speech recognition model that can identify professional terms for power grid operation, and creating a voice interaction platform suitable for the field of dispatching. Realize the intelligent operation of the whole process of intelligent service scheduling virtual robot.
With the service dispatching virtual robot "on the job" in the power dispatching and control center of Gui'an Power Supply Bureau, it has effectively realized the functions of automatic receipt, dispatch, overtime work order and returned work order reminder, automatic telephone notification to users of planned power outage information, automatic voice broadcast of business work orders, centralized control of disposal processes, etc., which greatly improves the efficiency of service scheduling and customer satisfaction, and directly reduces the number of times customers call the 95598 customer service hotline. At the same time, the robot autonomously optimizes the service scheduling business process, reduces the complicated intermediate operation steps, reduces the number of mis-dispatch and transfer of work orders, reduces the overtime of work orders, fundamentally makes up for the "short board" existing in manual operations, and effectively and orderly improves the operation level of "integration of deployment and control services".
According to estimates, since the service dispatching robot was officially launched in February 2020, the labor intensity of the regulators has been greatly reduced, the impact or mistakes caused by human factors have been completely eliminated, the timely processing rate and accuracy rate of all work orders have reached 100%, the number of times electricity customers dialing the 95598 customer service hotline has decreased by more than 30%, and the efficiency of the whole network service scheduling has increased by 50%.
Party building and strong leadership, prompting the "innovation flower"
All members of the gui'an power supply bureau control class are heroic and courageous, united and enterprising
Unorganized, insecure; uninspired, unindusted.
Keeping a close eye on the goal of "Chuangxing", Gui'an Power Supply Bureau set up a special team for the creation of the "South Grid Five-Star Team" and the Chuangxing Responsibility Group headed by the Secretary of the Party Branch of the Power Dispatching and Control Center, to clarify the creation time limit and target tasks, and promote the deep integration of party building and business, innovation and "Chuangxing" same frequency resonance.
Taking party building as the guide and party members as the vanguard, the regulation class deeply implements the "Guidelines for the 7S Management Of China Southern Power Grid Company" and the "Guidelines for the Construction of Team Culture of Guizhou Power Grid Company", takes the localization 7S concept as a higher standard of class management, puts forward the star-creating concept of "everyone is a manager", establishes five 7S working groups for safety management, education and training, fixed management, team culture, and lean improvement, and sets up party members as 7S management team leaders, positions them as organizational and service roles, and also gives them the right to control and decision-making.
In daily work, party members take the lead in "gnawing bones" and face challenges to break barriers. Pioneer party members Xiao Xiaotian, Shang Xiaoxia, huang Yang, in view of the traditional dispatch operation by the dispatcher on duty to order the patrol maintenance center, after receiving the order to the patrol and maintenance center and then send people to operate on the spot, many links, time-consuming, low efficiency of the facts, problem-oriented rapid project to carry out work, on the basis of research and demonstration, boldly enable the dispatch + remote control integration of the new type of operation ticket. Using the new operation ticket, the on-duty controller stays at home in the control room, and applies the remote control system to remotely control the substation to prepare self-projection, recloser and other equipment, and the average operation time is reduced from the previous 30 minutes to about 2 minutes. Such a change not only enhances the real-time control ability of the regulation and operation personnel on the transmission, transformation and distribution system and line load, but also reduces the flow of dispatching instructions, ensures the reliability of power supply, and improves service levels and customer satisfaction.
Coincidentally. Demonstration party members Yang Rui and Song Da actively led the research of the innovative project of "Design and Application of Automatic Report Generation Software commonly used for regional power grid dispatching and operation" in view of the fact that the previous dispatch weekly, monthly and annual reports were manually filled in, which required a lot of time and energy, and were prone to errors, and the invention was copyrighted by the National Copyright Administration. The soft book project, the use of scheduling operation logs and weekly reports, monthly reports and other types of reports relationship, the data to do the validity of the association, automatically generate relevant reports and have statistical analysis functions, to achieve automatic generation of data indicators in each time dimension, to achieve "a set of data, multiple sets of tables", reduce the data in the transfer process error rate and error, reduce the workload of the staff, greatly shorten the handover time, greatly facilitate the scheduling of daily business, and strong practicality, high economy.
With the joint efforts of the whole class, the lean project "Research and Application of 10 kV Distribution Network Comprehensive Power Outage Management Analysis and Decision-making Platform" won the Gold Award for On-site Improvement of Guizhou Power Grid Corporation, and the on-site Improvement Project of "Optimizing OS2 System Man-Machine Interface" won the Silver Award of On-site Improvement of Guizhou Power Grid "Lean Cup" 7S Management Labor Competition. The enterprising control class has won the honorary titles of "Worker Pioneer" of Guizhou Power Grid Company, "Youth Civilization" of Guizhou Power Grid, and "Five-star Model Worker Small Home" of China Southern Power Grid Company.
