Abstract: 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.

Abstract translation: 本发明涉及一种将DC网格的第一部分与DC网格的第二部分相互连接的HVDC开关场所。 通过本发明，DC电网的第一部分经由快速DC断路器连接到HVDC开关站的母线，而直流电网的另外部分通过以下方式连接到HVDC开关站的汇流条： 开关柜断路器的断开速度较低。 通过使用本发明的高压直流输电开关装置，可以显着地降低HVDC开关站的成本，同时可以提供足够的保护。 在一个实施例中，快速DC断路器是形成HVDC站的一部分的HVDC站DC断路器。 在另一个实施例中，快速DC断路器是开关站DC断路器。
