key words: management technology line loss in the first half of 2005, Harbin Rural Electrification Bureau completed 476.48 GWH of power supply, an increase of 60.43 GWH or 14.52% over 416.05 GWH in the same period of last year; The electricity sales was 450.94 GWH, an increase of 57.38 GWH or 14.57% over 393.56 GWH in the same period of the previous year; The comprehensive line loss rate was 5.36%, down 0.05 percentage points from 5.41% in the same period of the previous year. In the first half of 2005, 65.78 GWH of 0.4 kV power supply was completed, an increase of 19.44% over 55.07 GWH in the same period of the previous year; Electricity sales were 61.97 GWH, an increase of 20.05% over 51.61 GWH in the same period of the previous year; The low-voltage line loss rate was 5.80%, down 0.5 percentage points from 6.30% in the same period of last year. 1. The exploration of line loss management mode will not cause structural damage due to the failure of a component 1.1 improve the organization and improve the management system. Line loss management directly reflects the comprehensive management of power supply enterprises. Due to the small clinical sample size, it is also an important means for power supply enterprises to improve economic benefits. Therefore, the establishment of an efficient and perfect organization system is the foundation of loss reduction and power saving. According to the actual situation of Harbin Suburban Rural Power Bureau, a three-level loss reduction and energy conservation leading group was established, that is, the bureau established a line loss leading group headed by the director to be responsible for the overall loss reduction and energy conservation management; The planning department of the bureau sets up a level-2 line loss leading group to be responsible for the daily work of overall line loss management. Two comrades with comprehensive technical business are responsible for high and low voltage line losses respectively; Each power management office has set up a three-level line loss leading group to be responsible for the management of loss reduction and power saving in its jurisdiction. At the same time, it has set up part-time line loss officers in the Bureau's biotechnology office, dispatching room, business office, metering office, power consumption Inspection Bureau and other departments, improved the overall line loss management system, and formed a clear responsibility and authority, hierarchical management, providing an organizational guarantee for efficient loss reduction and power saving. 1.2 establish a scientific and reasonable assessment system. At the beginning of 2005, Harbin Suburban Rural Power Bureau organized relevant personnel to carefully discuss and compare the transmission and transformation loss indicators to the substation area according to the planned indicators issued by the Regional Bureau, combined with the electricity planning and the actual development of the power load in the power supply area, as well as the line loss indicators completed in the previous year, and according to the theoretical calculation value of the line loss, and divided the transmission and transformation loss indicators into the substation area, 10 kV indicators are formulated according to the line, and 0.4 kV indicators are formulated according to the substation area, After being reported to the line loss leading group of the Bureau for deliberation, evaluation and demonstration, it shall be submitted to the workers' Congress. After approval, it will be issued in the form of documents, and the economic status of energy conservation and loss reduction will be signed with 8 electricity management offices to ensure the completion of the indicators. Each power management office shall decompose the line loss index to each employee according to the line and station area, link the line loss index to the economic interests of employees, and take it as the main assessment content of the tenure objectives of leading cadres at all levels. Loss management achieved the unity of responsibility, power and interest, and fully mobilized the enthusiasm of employees. At the same time, the dynamic assessment of energy conservation and loss reduction shall be carried out according to the power operation status, and the line loss indicators of line technical parameters shall be adjusted in time to make the indicator formulation scientific and reasonable. 1.3 to strengthen line loss analysis and reduce management loss, line loss statistical analysis is an important link in line loss management. Every month, Harbin suburban rural power bureau insists on daily meter reading on a regular basis. It is enough to count the line tension range of 10n-500n on a monthly basis and according to the station area. Each unit timely analyzes the line loss statistics such as aerospace, automation, infrastructure and transportation planning data. The planning department makes a qualitative and quantitative analysis of the overall line loss management based on the analysis results of each unit, summarizes experience, finds out deficiencies, and formulates measures, The line loss leading group finds out the problems existing in the loss reduction and power saving work according to the global analysis report and deploys the next loss reduction measures. A regular line loss analysis meeting shall be held on a quarterly basis, and all relevant units shall report the problems existing in their quarterly loss reduction work and exchange good experience. According to the line loss analysis, the power consumption Inspection Bureau has formulated an inspection plan, conducted targeted surprise inspections, and irregularly conducted 24-hour power consumption supervision, so that power thieves have no opportunity to take advantage of it and the phenomenon of power theft is decreasing day by day. In this way, a complete line loss analysis system has been formed from top to bottom, and the loss reduction measures have been adjusted in time, so that the line loss can be controlled and managed. In the first half of 2005, there were 71 10 kV distribution lines, 13 lines with a loss rate of more than 8%, a year-on-year decrease of 4, 1206 0.4 kV low-voltage stations and 45 stations with a line loss rate of more than 8%, a year-on-year decrease of 12. 1.4 strengthen the business management and strictly implement the routine daily meter reading accounting, which is the main data source and basis for the loss reduction work. Harbin Suburban Rural Power Bureau strictly implements the routine daily meter reading and adopts the monthly meter reading by route, sequence and time to lay a good foundation for the line loss statistics. At the same time, the personnel who read the 10 kV line and the low-voltage meter reading personnel also read the meter on time every month to synchronize the high-voltage meter reading with the low-voltage meter reading and ensure the accurate statistics of the low-voltage line loss. In order to ensure the accuracy of the gateway meter of the Regional Bureau, the personnel of the electricity consumption Inspection Bureau are sent to read the meter together every month to ensure the accurate measurement of the gateway meter. In order to ensure the quality of meter reading, the method of reading meters every 10 for key lines, key stations and key customers is adopted, and the meter reading personnel are changed regularly to improve the technical and professional quality of meter reading personnel. The electricity inspection bureau is divided into five inspection teams. Each inspection team must complete the inspection tasks of one distribution line and five low-voltage platform areas door-to-door by line every month. At the same time, the business director, business section chief and audit section chief of each electricity management office must complete the meter reading quality inspection of one line and five stations, forming a layer by layer audit network in the overall situation, timely finding and solving problems, reducing management loopholes and reducing line losses. In the first half of 2005, a total of 4126 high-voltage users, more than 30000 low-voltage users and 71 defective high-voltage users were inspected, 35 rectification notices were issued, 3 cases of electricity theft were found, 6 households violated the regulations, and the amount of electricity recovered was 1.767 GWH, totaling more than 400000 yuan. 1.5 strengthen measurement management the key link to ensure the correct measurement of line loss management of measurement devices lies in measurement management. In the first half of 2005, Harbin Suburban Rural Power Bureau focused on strengthening measurement management and unified management of measurement devices according to
