The system considered in this book is given in Fig. 5.1. The HVDC system consists of two VSCs connected via a DC link. The control of converter VSC-1 is done by using DC voltage control, whereas the control of converter VSC-2 is done by active power control. In this chapter, the steady-state and transient behavior of control schemes in normal and fault

HVDC cable modelling for VSC-HVDC applications
2014 IEEE PES General Meeting | Conference & Exposition, 2014This 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 ...

Supply passive networks with VSC-HVDC
2001 Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.01CH37262), 2001In this paper, the steady-state model of the VSC-HVDC (voltage source converter based HVDC) system supplying a passive network has been developed. According to this model, the control strategy is presented. At the same time, the AC filter is designed based on analyzing the spectrum of the AC voltage generated by the VSC.

The trend in semiconductor developments has made the high-voltage direct current (HVDC) technologies based on voltage source converters feasible. This type of convertor has a number of potential advantages compared with “classic” HVDC, but deep analysis should be carried out before its integration in electric power system. In this paper, the results of
