Abstract

At different places worldwide EHV/HV connections partly consist of sections with underground power cables. Presently in the west of the Netherlands 20 km (i.e. 240 km single phase in total) of power cables is planned in a new 380 kV connection (Randstad380 project) grid to ensure sufficient transport capacity in the Randstad area for the next decades. One of the issues studied in this project is the uncertainty about possible over-voltages from resonances. The paper intends to give a discussion on types of over-voltages, transients and possible resulting resonances reported in literature for combined linecable circuits. These over-voltages include: switching overvoltage, temporary over-voltage and system-interaction overvoltage. System simulation results will be presented as well.
