Abstract

The present invention discloses a zone area reasonable line loss prediction method based on a data mining technology. The beneficial effects of the present invention are that: the method of the present invention aims to discover the potential correlation between the zone area characteristic data and the zone area line loss by using the actual sampling data of the zone area line loss and utilizing a data mining means to process the mass data, is reliable in data source by being compared with a conventional theoretical line loss calculation method, and can reflect the on-site actual line loss status better; the algorithm flow is simple and practical, and the efficiency is higher; a multiple linear regression model is compact in structure, can reflect the influence degrees of the characteristic parameters to the zone area line loss visually, and is easy to analyze the status of a zone area of unreasonable line loss; the method is easy for software realization, and can be integrated in a line loss management system more conveniently.

Description

technical field [0001] The invention relates to a reasonable line loss prediction method in a station area based on data mining technology, which belongs to the field of electric power system automation. Background technique [0002] Line loss is the power loss, power loss and other losses generated by various components or equipment in the power network during the transmission and distribution of electric energy. The line loss rate refers to the percentage of the power loss in the power network (line loss load) and the power supply to the power network (power supply load), and its calculation formula is as follows: [0003] [0004] The line loss rate is an important economic and technical index that comprehensively reflects the planning and design of the power system, the production operation and management level of the power sector. Reducing the line loss rate can bring considerable economic and social benefits. Our country implements voltage division, division, line ...
