Research And Implementation Of The Automated Testing Platform Of Power Quality Monitoring Device

For the power quality monitoring device testing department,testing system which meets the power company standard Q/GDW-10-393-2009 "technical specification for the power quality online monitoring device of standardized" will greatly improve the efficiency of detection.At the same time,it can provide manufacturers with relatively complete inspection report,to guide the manufacturers produce products that meet the requirements,to advance in today's intelligent power grid and standardization.Although the technical standard has been related to domestic and international standards of power quality monitoring device,due to its technical level and manufacturers of commercial competition,the detection of power quality monitoring device still has a lot of problems.The power quality monitoring device for digital and analog communication interfaces,and the detection is very different.The detection for power quality monitoring device for more staff manual operation of the grid has low detection efficiency,slow speed and its accuracy is not high.Therefore,the research and realization of power quality monitoring device automation test platform has great engineering application value and economic value.In the process of research and implementation of the platform,this paper expounds the basic concepts of power quality indexes and its corresponding reference standard and introduces the platform implementation involved in the c#programming language and SQL Server 2008 database technology application.Platform is analyzed according to the actual power grid by problems of demand analysis and interpretation on the basis of the platform of the four basic function modules:parameters setting,program testing,test report,and help module.To avoid signal is wrong under the condition of mining,mining,design of the detection signal and signal interval length.At the same time,this paper focuses on the platform of procedures to achieve process.Screenshot shows the practical application of automated testing platform power quality monitoring device.The automated testing platform power quality monitoring device has been put into use in Sichuan province electric power company Ganzi electric power supply company.It has greatly improved the efficiency of the grid work personnel's detection,and ensured the accuracy of the test report of power quality monitoring device.
