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 ...
On the development of a power quality benchmarking model
(IEEE, 2009)
The development of a Power Quality (PQ) Benchmarking model is presented. Practical results are discussed to motivate the need of adding value to recorded PQ data by means of benchmarking PQ performance. The importance, ...
Towards PQ regulation in Southern Africa
(IEEE, 2009)
This paper discuss the regulation of Power Quality (PQ) in Southern Africa from a user perspective
An overview of the application of phasor measurement units (PMUs) and network coherent data in an interconnected power network: a case for Namibia
(Elsevier, 2017)
This paper presents the technological background, the structure of a time-stamp for network coherent data and the emerging documentation on the data requirements for applications making use of network coherent data. ...
Attenuation effect with non-linear loads for small stand-alone grids
(IEEE, 2016)
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 ...
Quality of supply data mining
(IEEE, 2014)
Extracting useful network management information from a large volume of QoS data obtained all over a network can be simplified by innovative data mining techniques. The need for QoS expertise is reduced as interactive ...
The effect of real network phase disturbances on the calculation of IEC 61000-4-30 parameters
(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 ...
