A method and device for locking electric leakage users based on line loss monitoring

Abstract

The invention provides a method and a device for identifying electricity stealing and leakage users based on line loss monitoring. The method comprises the following steps of making statistics on the daily power loss of N days of a target feeder line and the user power of M users; correcting the daily power loss of the N days to obtain maximum daily power loss values and minimum daily power loss values of the N days; performing per unit value calculation by selecting the user power of the M users on the first day, the maximum daily power loss values and the minimum daily power loss values as reference values; drawing M user power curves, a maximum daily power loss curve and a minimum daily power loss curve by using the user power of the M users on the N days, the maximum daily power loss values and the minimum daily power loss values after the per unit value calculation respectively; and identifying the users corresponding to the user power curves between the maximum daily power loss curve and the minimum daily power loss curve as the electricity stealing and leakage users. According to the method and the device, the electricity stealing and leakage users can be quickly and accurately identified, and the loss of a power system can be retrieved.

Description

technical field [0001] The invention relates to the field of electric power technology, and in particular to a method and device for locking electricity stealing and leakage users based on line loss monitoring. Background technique [0002] With the rapid development of the power supply business, illegal acts of stealing electric energy have also occurred continuously, which has plagued the power supply enterprises for a long time. Driven by economic interests, some criminals use electricity stealing as a means of reducing costs and making huge profits, forming a phenomenon that has developed from personal electricity theft in the past to some professional gangs and even groups stealing electricity. The illegal act of stealing electricity not only caused huge economic losses to the country and enterprises, but also seriously disrupted the normal order of power supply and consumption, and caused bad social impact. Criminals' means of stealing electricity is also diversified,...

However, due to the main factors affecting the line loss rate, such as cable transformer relationship, power consumption business, power theft, leakage and other factors, that is, the abnormal line loss rate may be caused by the above factors such as line transformer relationship, power consumption business, etc., making it impossible to analyze

It can be seen that the efficiency of this method is also very low, and it is often impossible to find the real mutation point of the line loss rate or there is an abnormal change during the period when the mutation point cannot be found.

[0008] 4. In recent years, power supply companies all over the country have spent huge sums of money to install automated remote monitoring terminals. Although many power supply companies have basically achieved full coverage of all special transformer users, and use this system for round-the-clock monitoring, use this device to monitor whether the current loop is Open circuit loss, whether the voltage circuit is short-circuited and lost voltage, whether there is reverse polarity, whether there is a special alarm item, etc. to investigate and deal with the leakage of electricity. The reporting rate is still very high and the false reporting rate is also high, which still cannot meet the needs of the existing electricity inspection
