Problems solved by technology

[0003] At present, domestic systems with line loss statistical functions mainly include marketing system and metering automation system, but the theoretical calculation of line loss that cooperates with the two is still limited to manual construction of power grid topology, parameter entry and calculation data. In the calculation, only the parameter values ​​corresponding to key points such as representative reference points or reference dates are selected for calculation, which makes the accuracy of the calculation results open to question

Abstract

The invention provides a method of improving a power equipment line loss per unit calculation result. The method comprises the following steps of (S1) marking off a plurality of line loss theory data according to voltage classes, and (S2) determining currently-chosen line loss theory data, and determining a corresponding calculation mode according to the currently-chosen line loss theory data to achieve line loss rate calculated via the currently-chose line loss theory data. The plurality of line loss theory data comprises line loss theory data corresponding to a 0.4kV voltage grade, line loss theory data corresponding to 10kV voltage grade and line loss theory data corresponding to a 110kV voltage grade. According to the embodiment, automatic data statistic and calculation can be realized; and line loss rate calculation result accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of electric equipment line loss calculation, in particular to a method for improving the calculation result of electric equipment line loss. Background technique [0002] The line loss rate is an important economic and technical index in the production and operation of power supply enterprises, and it is also an important symbol to measure the technical level and management level of power supply enterprises. However, the line loss rate depends on the accurate calculation of the theoretical line loss value. As a result, the effective analysis of line loss and the effective formulation of loss reduction measures can be carried out. [0003] At present, domestic systems with line loss statistical functions mainly include marketing system and metering automation system, but the theoretical calculation of line loss that cooperates with the two is still limited to manual construction of power grid topology, parame...
