Abstract

The invention concerns a switchyard for interconnecting direct current power networks and a direct current power transmission system comprising such a switchyard. The switchyard comprises a number of interconnected entities comprising at least two main circuit breakers and a number of transfer switches, where each network has two connections to the switchyard, at least one via a transfer switch, each main circuit breaker has four connections in the switchyard, two at each end of the main circuit breaker and at least one via a transfer switch, and each network is joined with every other network via a corresponding path through at least one main circuit breaker as well as via a corresponding path bypassing all main circuit breakers.
