The effect of a reduced power quality on the energy efficiency of stand-alone generator systems
Debruyne, Colin; Rens, Johan; De Kock, Jan; Desmet, Jan (IEEE, 2016)It has already been thoroughly validated that the efficiency of direct online motors is susceptible towards certain power quality parameters such as voltage unbalance or harmonic voltage distortion. It can be assumed that ... -
The effect of real network phase disturbances on the calculation of IEC 61000-4-30 parameters
Rens, Johan; De Kock, Jan; Van Wyk, Willie; Van Zyl, Jacobus (IEEE, 2014)Real life network dynamic phenomena are used to demonstrate how the calculation of IEC 61000-4-30 parameters can be affected. The voltage frequency can change instantaneously at a point in the network due to a shift in the ... -
Testing of a predictive pole-slip protection algorithm on a real time digital simulator
Lamont, Lafras; Rens, Johan; De Kock, Jan (IEEE, 2016)Predictive pole-slip protection is not implemented in commercially available protection relays. All pole-slip protection relays on the market will only trip a generator after it has pole-slipped one or more times. A ...
