Line loss contribution degree analysis method and system based on relative gain principle

Abstract

The invention provides a line loss contribution degree analysis method and system based on a relative gain principle. The method comprises the following steps: firstly, carrying out key characteristicindex analysis on a typical network structure of a low-voltage transformer area; obtaining open-loop gain and closed-loop gain from each key characteristic index to the line loss of each element by using a control variable method; combining the properties and the characteristic indexes of the relative gain matrix with the relative gain matrix of the line loss of each element; and finally, extracting line loss contribution degree information of each key characteristic index according to the relative gain matrix. Compared with a traditional analysis method, the method has the advantages that data mobility is high, effective information of related data can be extracted in line loss management, the relative gain principle is applied, the calculation method of the contribution degree of the key feature indexes is researched, contribution degree information of the key feature indexes to line loss is extracted, and support is provided for subsequent energy conservation and loss reduction.

Description

technical field [0001] The invention relates to a line loss contribution degree analysis method and system based on the principle of relative gain, belonging to the field of distribution network control. Background technique [0002] The massive data of the power grid has been formed, and the characteristics of big data are becoming more and more obvious. There are many types of data, large volume, fast increment, and high real-time requirements. However, most of the current data has insufficient liquidity and a low value conversion rate. It is urgent to extract effective information from relevant data in online loss management. Contents of the invention [0003] Purpose of the invention: One purpose is to propose a line loss contribution analysis method based on the principle of relative gain, so as to extract the line loss contribution of key characteristic indicators to each component. A further object is to propose a system implementing the method described above. ...
