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 ...

VSC-HVDC Station With SSSC Characteristics
IEEE Transactions on Power Electronics, 2004Commercial installations of voltage-source converter-high voltage direct current (VSC-HVDC) are now in service as asynchronous link and as underwater/underground DC transmission. The research reported in his paper is directed to providing VSC-HVDC with synchronizing power and damping power so that after a transient the steady-state is reached in ...

In the case of VSC-based HVDC transmission systems, the transfer of power is controlled in the same way as in the case of a classic HVDC transmission. The inverter side controls the active power, while the rectifier side controls the DC voltage [33, 56]. With classic HVDC, the reactive power cannot be controlled independently of the active power.

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
