Evaluation of system losses due to harmonics in medium voltage distribution networks
(IEEE, 2016)
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 ...
Improved event based method for harmonic impedance assessment
(IEEE, 2016)
The quantification of harmonic emission requires an accurate model of the network harmonic impedances. A number of techniques have been proposed for the assessment of the network harmonic impedances to be practical and ...
Continuous harmonic impedance assessment using online measurements
(IEEE, 2015)
The quantification of harmonic emission requires an accurate representation of the network harmonic impedances. A number of techniques have been proposed to make the assessment of the network harmonic impedances practical ...
Real-time power system oscillation monitoring using synchrophasor measurements
(IEEE, 2015)
Inter-area oscillations impact negatively on power system stability and power transfer capability. Monitoring oscillations in real time can improve control of the power system. Synchrophasor data from Phasor Measurement ...
A practical evaluation of harmonic emission assessment
(IEEE, 2011)
This paper reports an evaluation of harmonic emission assessment. The results obtained by the Harmonic Vector Method are correlated to the behavior of harmonic active power by means of synchronized measurements in a ...
On the reporting of power quality
(IEEE, 2011)
The reporting of power quality (PQ) requires consideration as different users of information on Quality of Supply (QoS) have different needs. Reporting on the compliancy of voltage regulation in terms of a PQ standard can ...
The analysis of voltage and current unbalance by application of active and reactive power in the fundamental frequency negative-sequence components
(IEEE, 2012)
The behaviour of the fundamental frequency negative-sequence power components in unbalanced power networks is evaluated for possible information on the relative contribution by the supply and loading network. Previous ...
On-line performance monitoring of a transmission line using synchrophasor measurements
(IEEE, 2015)
Synchrophasors are increasingly being implemented to improve the understanding of network performance. This paper presents the use of voltage and current synchrophasors in the on-line performance monitoring of a transmission ...
The validation of single point measurements for the localization of multiple harmonic sources
(IEEE, 2010)
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 ...
Carbon‐14 radiolabeling and tissue distribution evaluation of MMV390048
(Wiley, 2016)
The antimalarial compound MMV390048 ([14C]-11) was labeled with carbon-14 isotope via a 3-step synthesis. It was obtained in a 15.5% radiochemical overall yield from carbon-14 labeled methyl iodide with a radiochemical ...
