Abstract:
A high voltage direct current (HVDC) switchyard is provided. The switchyard is arranged for interconnecting three or more sections of an HVDC power network, such as transmission lines, converters, or any other type of HVDC equipment. The switchyard comprises at least one main circuit breaker and at least four transfer switches. The at least one main circuit breaker and the at least four transfer switches are arranged so as to enable to individually disconnect any one of the at least three sections of the HVDC power distribution network. In an embodiment of the invention, the transfer switches which usually are comprised in direct current (DC) hybrid circuit breakers are used as selector switches, thereby reducing the number of main breakers in the switchyard.
