Adaptive tools to conduct harmonic analysis using time domain software

Abstract

The non-linear behaviour of HVDC converters causes distorted voltage and current waveforms in the HVAC network to which it is connected [1]. Typically frequency domain software is used for conducting harmonic analysis (penetration and impedance scan studies) and results are displayed as steady-state quantities not taking into account the dynamic behaviour of the system components. A time domain software package is utilized to perform harmonic analysis and consider the dynamic behaviour of the system components. Thus the contribution of this work is the development of adaptive (compact) tools to simplify harmonic analysis procedures for investigating integrated HVAC/HVDC systems using time domain software. Results are generated and it is found that the developed tools are effective for conducting harmonic analysis using time domain software
