Theoretical line loss level calculation evaluation method based on actual measurement operation parameters of regional power grid

Abstract

The invention aims at solving a problem that there is short of a solution to the evaluation of the theoretical line loss level of a regional power grid, and provides an effective theoretical line loss level calculation evaluation method. The method comprises the steps: presetting a plurality of voltage levels, which are used for evaluating the theoretical line loss level of the regional power grid, for a to-be-evaluated regional power grid; selecting a representative day to carry out the theoretical line loss calculation; obtaining the power supply amounts of a plurality of preset voltage levels, the power supply amount of the whole grid formed through the plurality of voltage levels, the theoretical line loss rate, and the theoretical line loss rate of a plurality of voltage levels, which are the same as the voltage levels, of a regional power grid at an upper level; and finally evaluating the theoretical line loss level through calculating the theoretical line loss level difference ratio K of the to-be-evaluated regional power grid. The method avoids the defects that the regional theoretical line loss level is evaluated through experience and there is short of scientific criterion in the prior art, is effective, and is higher in practicality and operability.

Description

technical field [0001] The present invention relates to the technical field of electric power system, in particular, relates to an effective evaluation method of theoretical line loss level, especially through real-time database and data mining technology, based on the theoretical line loss level evaluation method of regional power grid actual measurement operation parameters, the present invention At the same time, it also involves a calculation method of theoretical line loss level based on the measured operating parameters of the regional power grid, so as to provide a basis for evaluating the theoretical line loss level of the regional power grid. Background technique [0002] Line loss is the lifeblood of a power supply company, reflecting the effectiveness of a company's technology, management and other aspects of work. In the analysis of statistical line loss, power supply enterprises are often affected by factors such as large fluctuations in line loss rate and many ...
