Line loss problem analysis and defect elimination processing method

Abstract

The invention relates to a line loss problem analysis and defect elimination processing method and belongs to the electricity management field. An archival data center is established, the line loss situation of each region in each period is recorded, and the unreasonable regions are screened and classified; a standardized diagnosis center is established, a standard formula for diagnosing unreasonable causes of the regions is made, and tasks are assigned to relevant departments for processing; a centralized management center is established, the defect elimination process is recorded, and backtrack and statistics of the task processing situation are facilitated; a reporting system is established, statistical analysis of key links is carried out, so the management level can accurately grasp the information that they want to know. Through employing technical measures and management measures, line loss assessment and analysis of the regions are carried out on the monthly, quarterly and annual basis, management analysis of assessment indicators is strengthened, causes of problems are found out, problem decomposition and measure implementation are carried out step by step, follow-up analysis and assessment of implementation of the measures are carried out, and closed-loop control of management of the regions is realized. The method can be widely used in the field of power supply management and line loss management.

Description

technical field [0001] The invention belongs to the field of power supply management, and in particular relates to a method for analyzing and eliminating line loss problems. Background technique [0002] my country's electric power industry has entered a stage of "rapid development" in recent years. However, due to problems such as uneven energy distribution, problems that are contrary to the overall development direction and even hinder the development of electric power have appeared in various fields. [0003] In the marketing of low-voltage power, due to the current economic and technical constraints, although power supply companies at all levels have invested a lot of money in large-scale construction and transformation of low-voltage networks, due to the large number of low-voltage customer groups and frequent changes, At present, in the line loss management of the station area, there are generally abnormal line loss caused by management reasons such as unclear relation...

Problems solved by technology

[0003] In the marketing of low-voltage power, due to the limitations of current economic and technical conditions, although power supply companies at all levels have invested a lot of money in large-scale construction and transformation of low-voltage networks, due to the large number of low-voltage customer groups and frequent changes, At present, in the line loss management of the station area, there are generally abnormal line losses caused by management reasons such as unclear relationship between households and transformers, poor meter reading quality, power theft, and metering failures. Abnormal line loss caused by technical reasons such as too small conductor cross-section, overloaded line, insufficient reactive power compensation capacity, no-load and light-load transformers, etc.

[0004] In recent years, many domestic power supply companies have faced a common dilemma to varying degrees, that is, "large investment and small return" in the management of line losses in the station area. Various equipment transformations for low-voltage distribution networks have continued, but the benefits are increasing. The more unsatisfactory it is, the root cause is that in the past ten years, the main factors affecting the line loss in the station area have undergone tremendous changes, and the direction of investment in transformation remains unchanged, which will inevitably lead to a short-term rebound in quick-acting loss reduction, and it is difficult to solidify long-term loss reduction , orderly loss reduction, and finally fell into the dilemma of "large investment and small return"

[0005] At present, there are more than 16,000 station areas under the jurisdiction of a power supply company in Shanghai, the line loss is only more than 10,000, and the pass rate is less than 70%.
