Real-time Power Quality Monitoring and Analysis Platform of Rural Power Network Based on Virtual Instrument
A new design proposal of real-lime power quality monitoring and analysis platform based on virtual instruments technology is proposed that aims at the key issues that affecting the quality of rural power network.From steady-state to transient-state,this article discusses the typical algorithms of harmoniC analysis,voltage deviation and unbalance in threephase,voltage swells and dips,voltage fluctuation,transient oscillation and the theory of power quality disturbances detection based on Hilbert phase-shifting.Completing the software design of power quality monitoring and analysis platform based on NI (National lnstruments)-LabVlEW,which including visual design algorithm of the monitoring and analysis,graphical display of the calculation,analysis and display of the results,auxiliary we also use the FLUKE standard power source. The actual results show that the test results of our platform are accurate,the interfaces are friendly and the performances are steady and practical.
