Transformer district line loss rate flexible analysis algorithm process

Abstract

The invention relates to a transformer district line loss rate flexible analysis algorithm process and belongs to the electricity consumption management field. The flexible analysis algorithm process includes the following steps that: influences of reactive power compensation insufficiency and three-phase unbalance are eliminated for a transformer district of which the loss rate has a positive value, and a correction value of the loss rate is calculated; false wiring types of a current transformer in a load recording instrument are indentified through utilizing measurement data of a typical month; and the electricity supply quantity of the transformer district and the correction value of the loss rate are estimated according to the false wiring types of the current transformer in the load recording instrument and the measurement data. With the transformer district line loss rate flexible analysis algorithm process adopted, on the one hand, data exception can be identified and corrected, and on the other hand, cross influences of power factors and three-phase unbalance can be eliminated from the loss rate with a positive value, and therefore, transformer district line loss rate analysis results can become an authentic reliable basis for the discrimination of serious electricity stealing areas; the transformer district line loss rate flexible analysis algorithm process enables practical significances for power supply companies in electricity stealing-prevention working efficiency improvement and electricity stealing loss risk reduction. The transformer district line loss rate flexible analysis algorithm process of the invention can be widely used in the electricity consumption management field.

Description

technical field [0001] The invention belongs to the field of power consumption management, and in particular relates to an analysis and calculation method for the line loss rate of a station area. Background technique [0002] Anti-stealing is of great significance to maintaining power supply order, ensuring power security, and protecting the legitimate income of the country and power supply companies. At the same time, due to the concealment and dispersion of electricity theft, anti-stealing is also a problem that has plagued power supply companies for a long time. Since 2007, the Shanghai Electric Power Company began to implement the line loss refinement work. For the low-voltage station area, the line loss rate of the station area was obtained by comparing the power supply of the station area measured by the load tester and the total electricity sales of the station area during the same period, and then According to the high or low line loss rate, the area with high incid...

[0005] (2) Electricity inspection is still an important link in the anti-stealing of electricity. Efficient inspection requires a reliable source of information on suspected users of electricity theft. However, the current analysis method of line loss rate in the station area has two defects: ① through the supply and sale of electricity Abnormal data (zero or negative) in the line loss rate of the low-voltage station area obtained by comparison is very frequent, which may be caused by wiring errors during the installation of the load tester, or by the tester body or communication Fault problems, there may also be marketing management problems in the station area (such as variable-household mismatch, etc.), so that the line loss rate cannot be used as the basis for judging the hardest-hit areas of electricity theft; ② Even if a high positive line loss rate is found after comparison, It cannot simply correspond to the problem of high electricity theft, because the line loss rate is also affected by factors such as power factor and three-phase unbalance rate
