On the evening of August 10, the State Grid Dongying City Hekou District Power Supply Company (hereinafter referred to as "Hekou Company") development and construction department line loss special workers opened the "same period line loss management system" as usual to view the results released in July, "whether the top 100 counties, top 100" column appeared two "yes" for the first time, this is the company since December 2020 shortlisted for the top 100 creation qualifications, the first time to break into the "top 100 counties" queue, the company's urban power supply center became the first "top 100 institutes", achieving a double breakthrough in history.
"Since December last year, we have been on the road to creating the 'Top 100', and after more than half a year of hard work, we have finally gained" On August 11, liang Yongchao, head of the Development and Construction Department, was full of emotion when it came to the creation of the top 100 counties and the top 100 institutes.
Hekou company is small in size, the proportion of economic operation in the line and Taiwan area is low, large-scale demolition has brought great obstacles to line loss management, the company's "top 100 counties" and "top 100 institutes" indicators are often ranked behind in the city, and the creation of "top 100" is close to the fantasy for Hekou company... One label after another seems to tell Hekou that it is impossible to create a 'top 100', so "can it create a hundred strong, how to create a hundred" has become the thorn in the heart of the company's cadres and employees.
<b>The "top 100" is up</b>
No matter how difficult the top 100 are, they must eventually fight. The goal of Kawaguchi Company to jointly strive for the "Top 100" was finally set, but "how to create, how to go" made everyone think hard and study it repeatedly. The train runs fast, all thanks to the headband. Yang Ning, general manager of the company, and Li Pengfei, secretary of the party committee, took the initiative to claim the positions of leader and deputy leader of the line loss management leading group, built a "number one" responsibility system, and woven a three-level management network of "decision-making level, management level and execution level". The scope of responsibility of line loss management is decomposed, controlled and assessed according to the indicators of "partitioning, pressure division, division line and division area".
"It is necessary to concentrate on discussing and studying and formulating practical and feasible solutions, clarifying the improvement goals, adhering to seeking truth from facts, making steady progress, resolutely not letting go of every suspicious problem, ensuring that there is progress every week, and seeing results every month" On May 12, Hekou Company organized a professional management meeting on line loss, and Yang Ning, general manager of the company, attended the meeting and carefully emphasized the deployment of line loss management.
Combined with the actual situation of line loss management, "control daily loss" and "grasp high loss" has become the key to the promotion of "top 100" in Hekou Company, the company implements the management and leadership guarantee of the power supply station, organizes the operation and inspection, marketing and other professional departments to strengthen the specific management guidance of each power supply station, starting from the management and technical aspects, carry out the analysis of the correlation between high loss and negative loss in the Taiwan area, and rectify the problems found in a timely manner such as the inconsistency of household changes and the mutual supply and mutual belt of Taiwan and change. Establish a normal monitoring mechanism for qualified Taiwan areas, formulate special governance plans for rebounding Taiwan areas, and carry out cause analysis and countermeasure research in Taiwan district by district. The 46 Taiwan areas belonging to the new household office and the urban power supply center have been successively transformed from high-loss Taiwan areas into economic operation stations.
<b>The "Top 100" forge ahead</b>
"For this kind of situation where the load distribution of the taiwan area is uneven, the low loss of one district and the high line loss of one district, we can try to change the household change relationship in the right position" On May 27, the company's development department organized a contact and help to the new household power supply station in Bao Bao to learn more about the progress of the line loss management work this week.
In view of this situation, the staff organized on-site investigation, studied and analyzed the key factors of the problem one by one, and gradually realized the economic operation of 16 Taiwan areas by replacing the small multiplier transformer, changing the distribution position of the Station area, shortening the radius of power supply, returning the original line, migrating the transformer to the load center, etc. Gradually realized the economic operation of 16 Taiwan areas, which greatly improved the proportion of economic operation in the new household area.
On the afternoon of June 3, the sun was like fire, and the estuary ushered in the first hot weather of the year. Fu Yong, Sun Jian, Zhang Baoze, deputy general managers of the company, and Li Junshan, who was then the head of the development department, conducted on-site investigation in Longquan Village and Shengli Village in the demolition and relocation area, jointly studied loss reduction measures and formulated loss reduction plans. After on-site analysis and discussion, it was determined to dismantle the unloaded low-voltage branch line of Shengli Village, adjust the power access points of the scattered users, concentrate the low-voltage load near the transformer, move the demolition line of Shengli Village to Longquan Village, erect a line instead of the old line to supply power to breeding users, and solve the problem of power supply radius in Longquan Village. The experience of loss reduction in 2 Taiwan areas was quickly promoted in other power supply stations of the company, and 17 demolition and relocation areas were successfully reduced in June, effectively solving the important blockage problem in the creation of the company's "top 100 counties" and "top 100 institutes".
In order to continue to promote line loss management, the company pays attention to the summary of experience, for the demolition of the village and taiwan areas, the demolition of non-user low-voltage branch lines, the adjustment of decentralized user power access points, the low-voltage load is concentrated in a position closer to the transformer, reducing line losses. Focus on zero-degree meters and meters with large power fluctuations to plug management loopholes. Monitor the three-phase current situation at the peak load time of the evening and noon, adjust the three-phase load in the three-phase load area with a large imbalance, ensure the balance of the three-phase current in the station area, and reduce the increase in line loss caused by the three-phase load imbalance. For the station area where the load is located at the end of the low-voltage line, the position of the transformer is relocated so that it is in the center of the load, and the line loss is reduced, and the station area with long running time and serious line aging is included in the transformation project.
<b>The "Top 100" climbed to the next level</b>
Failures vary, there is only one kind of success. In the case of a slight improvement in the promotion of online loss, the company summed up the experience and practices in a timely manner, clarified the targeted solution strategy of various types of Taiwan areas, realized "a set of countermeasures for one type of Taiwan area", formed a rectification and governance template plan, and promoted and implemented it within the scope of the company to comprehensively improve the basic management level of line loss. Through continuous strengthening of control and the formulation of loss reduction measures, the company's line loss rate has gradually improved, and the double breakthrough of "top 100 counties" and "top 100 institutes" has been achieved in one fell swoop.
Recently, the "top 100" evaluation system of the State Grid Corporation has been adjusted more frequently, and the theoretical line loss and economic operation rate indicators of the line have become more important, and the calculation basis of the theoretical line loss is that the line and the taiwan area have complete and correct ledger parameters, topology diagrams and operating data in the integrated system. Time is not waiting for anyone, in order to continue to promote the creation of "top 100", Hekou Company quickly organized the transportation and inspection department and the marketing department personnel to carry out the route and the topology map of the Taiwan area in two ways. On the one hand, arrange experienced teachers on site to conduct on-site investigations, collect on-site equipment information, and draw offline drawings. On the other hand, the elite personnel were organized to rectify the PMS system and draw accurate GIS graphics, which were 100% integrated with the scene. After nearly two months of overtime work, the PMS graphics improvement work of 30 lines and 244 taiwan areas was completed, the information of the line and the taiwan area account was standardized, and the theoretical line loss calculation basis and the proportion of economic operation were improved.
In the next step, Hekou Company will continue to conscientiously implement the deployment of line loss work of provincial and municipal companies, aim at "special excellence", strive to make breakthroughs as the basic requirements, firmly establish the idea of "grasping line loss is to grasp efficiency", will strive for excellence throughout the entire process of line loss management, actively learn from advanced units, learn from each other's strong points, base on reality, strengthen problem orientation, do a good job in line loss management pre-control, promote line loss management to be solid and effective, and achieve the comprehensive management level of line loss "to improve quality and efficiency, go to the forefront".
