Power Quality Analysis

This paper presents a software design useful for power quality analysis and data management. The software was programmed in LabVIEW and Oracle, running on Windows in a regular PC. LabVIEW acquires data continuously from the lower machine via TCP/IP. Using its database connection toolkit, LabVIEW accesses to Oracle to stores and retrieve the power quality data according to different indicators. A friendly GUI was built for data display and user operation, taking advantage of the powerful data-handling capacity of LabVIEW and its rich controls. Moreover, Excel reports can be exported using report generation toolkit in LabVIEW. The software greatly improves the data analysis and management capacity.

Analysis System

The introduction of the virtual instrument technology provides new ideas for the developments of the temperature acquisition. This paper presents the design of temperature acquisition system based on VI technology. This system takes LABVIEW as the software development platform, simulating environmental temperature parameters via temperature sensors and heaters. Through the USB-6009 data collecting cards environmental temperature is sent to LABVIEW software platform for analysis. The system has the functions of data acquisition, display, storage, callback, save, analysis, printing statements and limit alarm processing and so on, and completes the real-time collection and analysis of the temperature.
