In terms of reinforcement to meet the minimum requirement for HVDC connection, several aspects can be considered. The AC side can be reinforced by increasing its voltage level, boosting its line rating (through a larger cross section), and/or installing new transmission lines. Existing AC lines ...

The deployment of a 765-kV transmission line on Eskom’s South African Grid marks the beginning of a new era in power industries. The integration of renewable energies by independent power producers (IPPs) leads to an infrastructural change in the stability performance of the entire grid. These...
A fault-location method for transmission lines using synchronized voltage measurements at both endings of the line is described in [11]. Reference [12] proposes a fault-location method for VSC-HVDC system transmission lines using an active impedance estimation technique. A fault-location method is ...
