Line loss rate benchmark value calculation method based on transformer area data feature classification

Abstract

The invention discloses a line loss rate benchmark value calculation method based on transformer area data feature classification, is applied to the field of power line loss management, and can perform line loss rate benchmark value calculation based on data feature classification on a transformer area. According to the method, a new K-means clustering algorithm is used to make the data classification of the station area more reasonable and the calculation result is more accurate., the transformer area data classification is more reasonable, and the calculation result is more accurate; the benchmark value calculation method is characterized by comprising the following steps of: firstly, analyzing an influence relation of a line loss rate influence factor on line loss, and selecting electrical characteristic parameters which have a relatively large coefficient of correlation with the line loss rate and are easy to obtain as variables for establishing a transformer area index function; and then, determining the initial clustering center of the clustering algorithm through the index function, so that the accuracy of the clustering result is improved, and a scientific theoretical basisis provided for the provided benchmark value determination method.A reasonable theoretical basis is provided for determination of the line loss rate benchmark value of the transformer area, the lineloss rate prediction calculation result is accurate and can serve as a data basis for benchmark value determination, an effective way is provided for line loss management of the transformer area, andlean and digital management of line loss management of the transformer area is easy to achieve.

Description

technical field [0001] The invention belongs to the field of calculation of line loss rate; in particular, it relates to a calculation method of benchmark value of line loss rate based on classification of station area data features. Background technique [0002] Line loss rate is an important economic and technical indicator for comprehensively evaluating the planning and design, production operation, technical management, and operation level of the power system, and it is also an important content for evaluating the management of the power sector. However, due to the characteristics of large scale, many nodes, long lines and wide area of ​​China's distribution network, the power loss of low-voltage distribution network accounts for about 40% of the entire power network loss. It is urgent to solve the problem of line loss, so accurate and simple line The loss calculation and analysis method has important guiding significance for the actual management work. The theoretical ...
