| 发明名称 | HVDC switchyard and an HVDC switchyard system | ||
| 摘要 | The present invention relates to an HVDC switchyard arranged to interconnect a first part of a DC grid with a second part of the DC grid. By means of the invention, a first part of the DC grid is connected to the busbars of the HVDC switchyard via a fast DC breaker, while further part(s) of the DC grid are connected to the busbars of the HVDC switchyard by means of switchyard DC breakers of lower breaking speed. By use of the inventive HVDC switchyard arrangement, the cost for the HVDC switchyard can be considerably reduced, while adequate protection can be provided. In one embodiment, the fast DC breaker is an HVDC station DC breaker forming part of an HVDC station. In another embodiment, the fast DC breaker is a switchyard DC breaker. | ||

| 主权项 | 1. An HVDC switchyard arranged to interconnect a first part of a DC grid with at least one further part of the DC grid, wherein the HVDC switchyard comprises: at least one busbar and at least two switchyard DC breakers; wherein: at least one of the at least two switchyard DC breakers, arranged to connect the first part of the DC grid to the at least one busbar, is a fast DC breaker;at least one of the switchyard DC breakers is of lower speed, said at least one lower speed switchyard DC breaker being arranged to interconnect a further part of the DC grid with at least one of the at least one busbar; andthe fast DC breaker is capable of providing a higher breaking speed than the at least one DC breaker of lower speed. | ||
