Abstract

The invention relates to the field of power distribution networks, and provides a method and a device for metering power consumption in a power distribution network. The method comprises the following steps of acquiring metered values of voltage and power consumption of a plurality of user nodes; obtaining the voltage drop of the user nodes relative to a bus according to the metered values of the voltage; acquiring a feeder correlation matrix R of a feeder where the user nodes are located, wherein the feeder correlation matrix R represents a linear relationship between the voltage drop of the user nodes on the feeder relative to the bus and the power consumption of the user nodes; judging whether the metering of the power consumption is abnormal or not according to the feeder correlation matrix R, the voltage drop of the user nodes relative to the bus and the metered values of the power consumption. According to the method and the device, a power distribution system can be helped to identify probable electricity stealing behaviors.

Description

technical field [0001] The present invention relates to electricity distribution networks, and in particular to methods and apparatus for handling electricity consumption metering in electricity distribution networks. Background technique [0002] Electricity theft is a problem that has always been faced by power distribution systems. The annual energy loss due to electricity theft can be as high as tens of millions of kilowatt-hours. Due to the extremely complex power distribution network and the large number of customers faced by the power distribution system, there is currently no effective mechanism to help the power distribution system detect or identify possible power theft. Contents of the invention [0003] Therefore, there is a need for a solution that can help power distribution systems identify possible power theft. [0004] According to an aspect of the invention there is provided a method for handling electricity consumption metering in an electricity distri...
