Possibilities for determining the interference between a power supply network and a converter fed drive

Measuring instruments, measurement methods, and an exemplary analysis of the impact of chosen operating stages of the converter drive on the power supply network have been presented. The measurements of electrical and mechanical parameters in drive systems used in industry are complex. The task is difficult due to the necessity of connecting a measuring instrument into electric circuits of an active facility with the use of only short non-operational periods of the device. However, a wellchosen model of a drive system allows the multivariate research of the impact of drive parameters and a control algorithm used on voltage and current harmonic content and performance of the system, and therefore on a simulation analysis of the impact of the drive on the power supply network.
