Nyakureba, Mike (2018) Impact of Harmonics from 12-pulse Converter-Fed DC Drives. [USQ Project]
Abstract
Power system harmonics are a dominant topic when considering power quality issues in power systems due to the increased use of nonlinear harmonic producing loads such as electronics-based motor drives. Harmonic Analysis is therefore necessary to ensure compliance to the relevant standards , identify harmonics, build models of Variable Speed Drives and relevant components of the connected power system are evaluated. The analysis of the results can be used to aid the design of additional harmonic mitigation measures.
This thesis is to carry out an analysis of the harmonics from twelve-pulse converter fed drives and to identify the power quality issues , the impact and mitigatory measures. The thesis details the fundamentals of basic theory of rectifiers, harmonic theory, the multi-pulse topologies Methodology and an analysis of the results and mitigation measures.
The basis of this thesis is the MIM twelve pulse rectifier-fed drive for the winder that located is underground. However, this project will focus mainly on the analysis of harmonics and their effects on transformers and the recommended strategies to reduce detrimental impacts thereof. Through simulations and field measurements at identified locations, the analysis is expected to determine the harmonic content and waveform distortions and come up with a judgement of harmonic compliance based on the results.
