Abstract

A method for on-line calculation of theoretical line loss of distribution network is provided. Based on the integrated power and line loss management system, from the PMS, the marketing basic data platform accesses the equipment archive data, access line topology data from the PMS system, from the electric power information acquisition system and the electric energy acquisition system to the operation data of the distribution network, on-line generation of distribution network topology diagram, maintenance of distribution network topology diagram, and then according to the work needs of the selection of equivalent power method or forward-backward power flow method for theoretical line loss calculation of distribution network, online query calculation results and automatic generation of analysis report. The on-line calculation method of the invention realizes the functions of automatic data collection-automatic data integration-automatic theoretical line loss calculation-line loss result report summary analysis of the theoretical line loss calculation of the distribution network, so as to improve the automation degree of the current distribution network line loss theoretical calculation, reduce the workload in the line loss theoretical calculation, and improve the distribution network operation benefit of the company.

Description

technical field [0001] The invention relates to the field of theoretical calculation and analysis of power network loss, in particular to an online calculation method for theoretical line loss of distribution network lines. Background technique [0002] Theoretical calculation of line loss is an important technical means for line loss management and analysis. Through theoretical calculation, the composition of losses in the power network can be more accurately understood, and a reliable basis can be provided for fully tapping the loss reduction potential of power grid enterprises, especially for different investment plans. Theoretical calculation of line loss is particularly important. [0003] The distribution network is at the end of power production, transmission, and distribution. Its large number of equipment, wide coverage, and low voltage level lead to large losses in the distribution network. Excessive distribution network loss reduces the utilization efficiency of ...
