Abstract

The invention provides a method and a system for configuring a business expansion metering device based on a knowledge graph. The method comprises the following steps of: S1, acquiring business expansion information of historical users and operation data corresponding to the business expansion information; S2, constructing a typical configuration information table according to the business expansion information; S3, calculating the information gain ratio of each type of information in the configuration information table, and constructing a metering device configuration decision tree; S4, obtaining a business expansion demand of a new user, and generating a plurality of configuration schemes corresponding to the business expansion demand through the metering device configuration decision tree; and S5, performing quantitative evaluation on the configuration scheme according to the operation data, generating an evaluation report, and performing visual display. By means of the mode, the configuration scheme obtained by the user can better meet the actual requirement while the configuration scheme making efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of electric energy metering device configuration, in particular, to a method and system for configuring a business expansion metering device based on a knowledge map. Background technique [0002] At present, the number of metering devices is large and the frequency of use is high, which is closely related to power grid planning, power grid trading, power dispatching and quality assessment. With the reform of my country's electric power system, higher requirements have been put forward for the work of electric energy measurement, especially the transformation from the traditional planned economy to the market economy, the electric energy measurement technology is more important, and its integrity and accuracy need to be paid attention to. Electric energy measurement is directly related to the calculation of various technical and economic indicators such as power system power generation, line loss, fa...
