Method for quickly testing consistency of PQDIF (Power Quality Data Interchange Format) files

Abstract

The invention relates to the technical field of power equipment testing, and particularly relates to a method for quickly testing the consistency of PQDIF (Power Quality Data Interchange Format) files. The method comprises the steps of setting basic parameters for testing the PQDIF files through a power quality monitoring system, generating PQDIF files to be tested, carrying out a test on a grammar property of the PQDIF files, carrying out a test in allusion to the data integrity of the PQDIF files, and carrying out a test in allusion to the data accuracy of the PQDIF files. According to the invention, a power quality monitoring device is provided through analyzing difficulties existing in PQDIF file consistency testing at present, the PQDIF file consistency is tested quickly, automatic processes of PQDIF file generation, reading, analysis, test and the like are realized based on output control for Fluke 6100A series power quality standard sources, and tests for the data integrity and the data accuracy of the PQDIF files can also realized, thereby improving the efficiency and the quality of network access detecting operations of the power quality monitoring device.

Description

technical field [0001] The invention relates to the technical field of power equipment testing, in particular to a method for quickly testing the consistency of PQDIF files. Background technique [0002] According to the research and application of IEC61850 technology in the field of power quality monitoring, the development of communication protocols for power quality monitoring devices can be divided into two stages, with 2011 as the dividing line. Before 2011, all power quality monitoring devices used manufacturers' private communication protocols. After two years, more and more power quality monitoring devices adopt IEC61850 as the standard communication protocol. From the perspective of technological advancement, IEC61850 is an inevitable development trend of power quality monitoring devices. As of now, private communication protocols of manufacturers still occupy a certain market, especially the existence of stock power quality monitoring devices, so that the sharing o...

Problems solved by technology

[0004] In areas where PQDIF is used as the data exchange standard, the consistency detection of PQDIF files is a necessary detection item for the network access detection of power quality monitoring devices. The so-called PQDIF file consistency detection mainly checks the structure and Whether syntax, data integrity, data correctness, etc. meet the requirements of IEEE1159.3 and local regulations, but PQDIF, like IEC61850, is also a freely implementable and very flexible standard based on XML language. IEEE1159.3 allows PQDIF files Use custom labels and different file structures; and there are many power quality parameters, and a PQDIF file may contain data records of hundreds of parameters. These actual conditions make the consistency detection of PQDIF files very difficult, especially for PQDIF file data The check of completeness and data correctness, taking the check of PQDIF file data integrity as an example, basically relies on manual work at present. The main method is: import the PQDIF file into the power quality monitoring system, and then use the system’s trend curve query function, Query whether the trend curve of power quality parameters exists one by one; if it exists, the data is considered complete, otherwise the data is considered incomplete, this kind of checking work efficiency is very low, and the checking of the correctness of PQDIF file data is currently impossible
