The validation of single point measurements for the localization of multiple harmonic sources
Power quality management requires inexpensive and simple methods for electric power quality monitoring. This paper investigates the validity of single point measurements for the localization of sources of waveform distortion ...
Attenuation effect with non-linear loads for small stand-alone grids
This paper presents the effect of non-linear loads on the overall voltage quality in small powered stand-alone (islanded) systems. The iterative effect between current and voltage distortion is related to the source's ...
The effect of a reduced power quality on the energy efficiency of stand-alone generator systems
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 ...
Evaluation of system losses due to harmonics in medium voltage distribution networks
Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future ...
The effect of real network phase disturbances on the calculation of IEC 61000-4-30 parameters
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 ...
Modeling and validation of losses due to unbalanced loading of stand-alone generators
The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal ...
