Judgment Method for Abnormal Loss of Power Grid Components

Abstract

In order to solve the problems existing in the judgment of the abnormal loss of the existing power grid components, the present invention provides a method for judging the abnormal loss of the power grid components. Statistical line loss rate and theoretical line loss rate of the power grid components, and obtain the difference between the statistical line loss rate and theoretical line loss rate; set the power grid component loss abnormal threshold K, when the difference between the statistical line loss rate and theoretical line loss rate If the absolute value of is less than K, the loss of the selected grid component is considered normal; otherwise, the loss of the selected grid component is determined to be abnormal. The present invention abandons the traditional way of judging based on the statistical line loss rate fluctuations and empirical values ​​at the end of the month, avoids the disadvantages of management lag, and effectively solves the traditional judgment of abnormal power grid component loss based on empirical values, which is not suitable for fine management of line loss Requirements, with high economic and practical value.

Description

technical field

[0001] The invention relates to the technical field of electric power systems, and relates to a method for judging abnormal loss of power grid components, in particular to a method for judging whether the power grid component loss is abnormal according to the magnitude of the difference by comparing the theoretical line loss rate of a representative day with the statistical line loss rate. 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 abnormal values ​​of line loss rate. Therefore, reasonable loss reduction measures cannot be proposed only by analyzing statistical line loss rate. Theoretical line loss calculation of the power grid is one of the important technical means adopted by ...
