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 ... -
Impact of aggregation interval on harmonic phase angle measurements
(IEEE, 2018)The aggregation principles of IEC 61000-4-30 is a well-known concept implemented in Power Quality (PQ) recorders. Only rms data is retained. Harmonic emission assessment requires the analysis of harmonic phasors. Continuous ... -
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, ... -
Power quality grid code compliance for renewable power plants in South Africa
(IET, 2019)The introduction of renewable generation to South Africa's grid has introduced challenges to the management and regulation of power quality (PQ). These have been addressed by establishing PQ compliance criteria in line ... -
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 ...
