POSSIBILITIES FOR DETERMINING THE INTERFERENCE BETWEEN A POWER SUPPLY NETWORK AND A CONVERTER FED DRIVE
Journal Title: Power Electronics and Drives - Year 2017, Vol 1, Issue 1
Abstract
Background: This article presents the methodology that enables the analysis of the impact of the converter drive on the power supply network and the impact of the network on the drive to be performed. Material and methods: The key points in such an analysis are: the use of an appropriate measuring system that is chosen in terms of possibilities, the ability to take precise measurements, the correct determination of drive parameters, the simulation that reflects the normal behaviour of a system, the determination of quality of operation parameters that are relevant due to the impact of the drive on the power supply network, and arriving at the right conclusions after the analysis. Results: The applied methodology, which allows for the multivariate analysis of the impact of the converter drive on the power supply network and the possibility of analysing the impact of the network on the drive. Conclusions: The comparison of measurement results with the drive simulation results indicate that there is high correspondence between these waveforms, both in reference to the voltages and currents powering the frequency converter and the currents powering the motor.
