Abstract

The invention relates to a method and system for determining the loss of a low-voltage transformer area based on power consumption collection data, and the method comprises the steps: obtaining the power consumption high-frequency collection data of each user sub-meter in a first preset time period, and obtaining the power supply metering value of a transformer area total meter in each second preset time period, obtaining freezing power consumption of each user sub-table in each second preset time period; determining a transformer area line loss expression of the low-voltage transformer area in each second preset time period; determining a statistical line loss equation of the low-voltage transformer area in each second preset time period; establishing a statistical line loss equation set,and solving according to the power consumption high-frequency acquisition data, the power supply metering value and the frozen power consumption so as to determine the metering error of each user sub-meter in the low-voltage transformer area, the fixed loss of the transformer area and the equivalent resistance of each branch; and substituting the metering error of each user sub-meter in the low-voltage transformer area and the equivalent resistance of each branch into a transformer area line loss expression, and determining the transformer area line loss of the low-voltage transformer area.

Description

technical field [0001] The present invention relates to the technical field of electric energy metering, and more specifically, to a method and system for determining the loss of a low-voltage station area based on electricity collection data. Background technique [0002] Because the network of the low-voltage power network is relatively complex, and the load distribution is uneven, and the information of each part of the line is incomplete, it is very difficult to calculate the line loss accurately, so generally only a simplified method can be used for calculation. There are two methods commonly used, namely, the loss rate method of the platform area and the voltage loss rate method. Among them, the station area loss rate method needs to measure the power loss and loss rate of each typical station area, and the actual measurement needs to draw a low-voltage power network network wiring diagram, and divide the calculation line segments of the main line and branch line of th...
