HVDC cable modelling for VSC-HVDC applications

2014 IEEE PES General Meeting | Conference & Exposition, 2014
This paper assesses the impact of commonly used cable modelling techniques on the accuracy and simulation speed of detailed VSC-HVDC models for a range of typical studies. The results show that the choice of cable model can have a significant impact on the accuracy of the VSC-HVDC models and that employing a higher fidelity cable model does not ...
