General line loss analysis method

Abstract

The invention relates to a general line loss analysis method, which comprises the following steps: firstly, taking a database platform as a foundation to finish the preparation of graphics and data; sending various pieces of prepared data into a line loss calculation module to carry out the analysis of major network line loss and distribution network line loss; sending the line loss and a tidal current result obtained by calculation into an analysis module; sending calculation and statistical results into a database so as to bring convenience to automatically generate a summarization result; carrying out reactive optimization to compare the calculation result with the line loss measured by practical data; and carrying out summarization result statistics on the current-level line loss, and generating a statement. The general line loss analysis method is adopted to analyze factors, which affect the line loss, in a line, can cause an influence degree on the line loss by each line loss factor to be clear, and sets a loss reduction target to further optimally control a line loss value so as to provide a line loss calculation and analysis result for administrative departments and make a reasonable and effective loss reduction plan.

Description

technical field [0001] The invention relates to the technical field of line loss management in power supply and distribution, in particular to a comprehensive line loss analysis method. Background technique [0002] The power distribution system refers to the part of the power system that directly serves users. Because the distribution network is connected to the user end, it has the following characteristics: the structure of the distribution network is mostly a radial tree structure, with many branches and the number of nodes. The distribution network generally adopts a ring structure design and operates in an open-loop mode; the equivalent resistance R value of the line parameters is relatively large; the random variability of the load is large; the distribution network database has a large scale, many variables, and a large calculation workload; The problem of unbalanced three-phase load in the power grid is relatively prominent; the distribution network develops rapidly...
