Recognition method of electric energy metering equipment in scd file based on multi-keyword matching

Abstract

The invention provides an electric energy metering device identification method in a SCD (Substation Configuration Description) file on the basis of multi-keyword matching. The method comprises the following steps: according to an xml (Extensive Markup Language) normative structure, carrying out analysis to obtain a whole-station device tree; independently matching the name and the description of each logic device with the keyword of the logic equipment, and obtaining a weight according to a matching degree; independently matching the name and the description of each data set in each logic device with the keyword of each logic device, and obtaining the weight according to the matching degree; matching logic node type names contained in a data set entry with the keyword to obtain the weight; and traversing all data sets under the logic device, calculating a total weight (total K), identifying that the current logic device is an electric energy metering logic device if the total k is greater than a preset weight, and recording the position of the logic device in the whole-station device tree. The electric energy metering device identification method improves identification accuracy, reduces manual intervention workloads and improves the identification accuracy and efficiency of automatic software on the whole-station electric energy metering device.

Description

technical field [0001] The invention relates to a method for identifying electric energy metering equipment, in particular to a method for identifying electric energy metering equipment in SCD files based on multi-keyword matching. Background technique [0002] SCD file is the abbreviation of substation system configuration description file, which is composed of extensible markup language (xml), and describes the instance configuration and communication parameters of all IEDs (Intelligent Electronic Devices) in the substation, the communication configuration between IEDs and the primary system structure of the substation; The substation includes different IEDs, and each IED includes several LDs (logic devices); the energy metering (Meter) logic device (LD) is included in some IEDs, and it is necessary to identify the energy metering logic device by analyzing the SCD file. [0003] In order to identify the logical equipment of electric energy metering, there are two methods: ...

Problems solved by technology

[0004] Since the content of the SCD file is automatically generated by the program when the SCD file is transferred, manual verification is often not performed; the above-mentioned electric energy measurement identification method has simple judgment conditions. Missed judgment of electric energy metering equipment; and because the SCD file has a large amount of information, often millions of lines, after the automatic identification of the previous program, it is impossible to carry out manual inspection. , before investing a lot of time and effort in checking
