Problems solved by technology

[0003] In the 61850 server module of the power quality monitoring terminal, the measurement data is mapped to the leaf node of the logical device of the ICD file through the short address, and the 61850 client module can only obtain the required data through the specified leaf node. There are many leaf nodes in the middle, and it is impossible to manually find the leaf nodes in the ICD model read by the client and configure them manually. Therefore, how to identify which leaf node can obtain Ua or other dimensions requires a power quality ICD model The method of automatic dimension matching of middle leaf nodes

example 1

[0029] Example 1: In the DataSet data set, look up the instance number of the logical device, specifically: in Table 2, look up the instance number of the logical device;

[0030] Such as: MMXU1 basic data (real-time data), its instance number is inst=1;

[0031] Secondly, in Table 1, find the leaf node path corresponding to the instance number of the logical device, and replace the character "?" or character "*" in the path with the instance number of the logical device;

[0032] Such as: will the MMXU in Table 1? Replace the "?" in 1 with 1; Dimension rtFreg, frequency real-time measurement value, leaf node path MMXU? $MX$Hz$mag$f becomes MMXU1$MX$Hz$mag$f; get the dimensional leaf node path.

example 2

[0033] Example 2: According to Table 1, it can be known that: the MSQI sequence component value (real-time data), whose instance number is inst=1,

[0034] In Table 2, replace the character "?" in the path with 1;

[0035] Get: rtImbNgV, voltage negative sequence unbalance real-time measured value, leaf path MSQI? $MX$ImbNgV$mag$f becomes MSQI1$MX$ImbNgV$mag$f.

[0036] MHAI harmonic data (real-time data) with inst=1, the MHAI in a)? Replace the "?" with 1.

[0037] The present invention establishes the ICD file, establishes the relationship table between various dimensions of the power quality monitoring terminal and the corresponding leaf node path, and the original method: the 61850 client parses out that there are many leaf nodes in the ICD model, and no certain leaf node is known The meaning represented (in the icd model in the power quality monitoring terminal, the similar leaf node paths represent different meanings of dimensions), which can be efficiently obtained b...

Abstract

The invention belongs to the technical field of the power quality monitoring, and specifically relates to a leaf node automatic dimension matching method in a power quality ICD model. The solved technical problem is to provide an automatic and efficient leaf node automatic dimension matching method in the power quality ICD model. The adopted technical scheme is that the leaf node automatic dimension matching method in the power quality ICD model comprises the following steps: S10, establishing an ICD file; S20, establishing a relation table of various dimension of a power quality monitoring terminal and the corresponding leaf node path; S30, creating an ICD automatic matching model; S40, reading the ICD automatic matching model through the 61850 client module, analyzing the leaf node patchand matching the dimension; the method is suitable for the power system.

Description

technical field [0001] The invention belongs to the technical field of power quality monitoring, and in particular relates to a method for automatically matching dimensions of leaf nodes in a power quality ICD model. Background technique [0002] In order to vigorously promote the standardization of power quality terminals, it is required that the inspection departments of provincial electric power companies and the Provincial Electric Power Research Institute and other units have the power quality monitoring terminal verification capabilities, and the power quality monitoring terminals to be installed must be tested for network access; The monitoring terminal needs to have a 61850 server module, so that in the power quality monitoring terminal automatic verification system (abbreviation: verification system), the measurement data acquisition module needs to have a 61850 client module that supports simultaneous communication with multiple 61850 server modules. [0003] In th...
