This paper presents the virtual instrument used to monitor and analyze the behavior of Uninterruptible Power Supplies (UPS) system. The monitoring system includes: Hall effect sensors, data acquisition board, the LabVIEW environment and PC host. The applications enable the equipment to perform the functions of digital scope and analyze the following parameters: harmonic content, total harmonic distortion...
The momentum of today is focused on smart grid facilities that allow green energies to be used in electrical networks. But an important issue is to have powerful tools at hand able to measure power quality parameters in a flexible way in such grids. This paper present a flexible system designed and implemented to monitor power quality parameters in the power grid. Not only real time monitoring was...
A new monitoring method of power quality based on the industrial computer is proposed. Using fast Fourier transform, synchronous sampling signal from the data acquisition card is processed. This system can analyze and display the power quality parameters. The results of the experiment show that the system can monitors and analyzes the power quality parameters in power systems with long time, and harmonic...
