In a multiterminal HVDC network, dc circuit breakers (CBs) are required at each end of a line to selectively isolate a fault. Several CB concepts have been implemented in PSCAD, which differ significantly in their structure and performance. This paper describes the interaction of the different HVDC CB topologies with a meshed four-terminal network and assesses their performance in terms of maximum...
The operation of PWM motor drives with long cables results in several undesired phenomena. In order to avoid them all, it was proposed in a previous work that the long cable be used to connect the rectifier to the inverter, which would then be placed beside the motor, thus establishing a DC line transmission. In the mentioned work, the additional benefit of the proposal, which is the reduction of...
