Anti-electric larceny management method under condition of access of distributed generation

Abstract

The invention discloses an anti-electric larceny management method under the condition of the access of a distributed generation. The method comprises four steps: I, determining self-generating capacity under the access of the distributed generation of a user; II, determining the predicted value of monthly electricity consumption after the user installs the distributed generation; III, determining a monthly actual electricity consumption value after the user installs the distributed generation; IV, comparing the predicted value and the actual electricity consumption value, judging whether electric larceny occurs or not, performing lateral comparison according to the predicted value and the actual electricity consumption value respectively obtained in the step II and the step III, and if the predicted value is greater than the actual electricity consumption value, judging that the user has suspicion of electric larceny. According to the anti-electric larceny management method disclosed by the invention, by fully utilizing mastered measurement data, electricity consumption data and the like, the user with the suspicion of electric larceny is accurately screened out; on the premise that the current line loss per unit is incapable of effectively helping a power supply enterprise to narrow the electric larceny range, when the invisibility of the electricity consumption of the user is not in favor of screening out the user with the suspicion of electric larceny, the suspicion of the electric larceny user can be effectively screened out, and the loss of the power supply enterprise is effectively retrieved.

Description

technical field [0001] The invention belongs to the technical field of electric power operation, and in particular relates to an anti-stealing electricity management method. Background technique [0002] The flood of power theft has been plagued by power companies, causing huge economic losses to the country, with annual losses exceeding 20 billion yuan, seriously disrupting the order of the market economy. With the development of science and technology, the means of stealing electricity are becoming increasingly concealed and diversified. However, the current anti-stealing technology has great limitations, which can be mainly divided into two categories. One is to design a watt-hour meter with anti-stealing function, which fundamentally eliminates the possibility Electricity theft meters are often costly, and the operability of replacing all user electricity meters is poor, and the problem of electricity theft cannot be improved in a short period of time; through the analy...

Problems solved by technology

However, the network access of such enterprises and household "micro power stations" will change the size and direction of the power flow in the distribution network, thereby affecting the network loss of the distribution network, which makes the traditional method of judging electricity theft based on the line loss rate invalid. At the same time, Since the user's power generation is difficult to track and determine, the actual power consumption of the user is more hidden, which will bring certain difficulties to the anti-theft work
