    Abstract: Embodiments of the present invention are generally based on employing a power transmission line (160) in a HVDC link to provide auxiliary power to one of the ends of the HVDC link for facilitating a black start thereof when the HVDC link is de-energized, i.e. when at least one of the HVDC converter stations (140, 150) is de-energized and there is no transmission of power between inverter and rectifier HVDC converter stations (140, 150) on each side of the HVDC link. A relatively small amount of power can be conveyed towards one of the HVDC converter stations (140, 150) via the power transmission line (160) so as to provide power to any auxiliary system(s) of the converter station (140, 150), for example prior to a black start of the converter station (140, 150) being carried out.

    Abstract translation: 本发明的实施例通常基于在HVDC链路中采用电力传输线路（160）以向HVDC链路的一端提供辅助电力，以便在HVDC链路断电时促进其黑启动，即 当HVDC转换站（140,150）中的至少一个被断电并且在HVDC链路的每一侧上的逆变器和整流器HVDC转换器站（140,150）之间没有电力传输时。 能够经由输电线路（160）向相对于HVDC转换站（140,150）中的一个输送相对少量的功率，以向转换站（140,150）的任何辅助系统提供电力， ，例如在执行转换器站（140,150）的黑启动之前。

    Abstract: A converter arrangement (300, 301) is disclosed, which is configured to couple an AC power system (102, 302) with a DC power system (103). The converter arrangement (300, 301) comprises a plurality of converter modules (100) electrically connected in series at a DC pole (Tl, T2, T7, T8), for example between a first DC pole (Tl, T7) and a second DC pole (T2, T8), or between a DC pole and ground. At least one converter module (100) is configured such that the at least one converter valve (151-1, 151 -N, 152-1,..., 152-N, 153-1, 153-N, 154-1, 154-N, 155-1, 155-N, 156-1, 156-N) thereof is controllably switchable between conducting states with a selected current conduction direction and a non-conducting state so as to selectively control polarity of any voltage contribution provided by the at least one multi-level converter cell (141-1,..., 141-N, 142-1, 142-N, 143-1, 143-N, 144-1, 144-N, 145-1, 145-N, 146-1, 146-N) of the converter module (100).

    Abstract: The invention relates to a voltage source converter (100) and energization thereof. The converter comprises a plurality of converter modules (102) connected in series between DC terminals of DC power system. Each converter module is further connected with AC terminals of a phase of an AC power system, for conversion between DC and AC power. Each converter module has director valve arms (D1,D2) and wave shaper arms (WS1,WS2). The director valve arms comprise antiparallel thyristor pairs and the wave shaper arms comprise cell capacitors. The converter can be energized in a first mode from the AC power system and in a second mode from the DC power system. In the first mode, a duration of turning on of the thyristors is controlled. In the second mode, the connection and bypassing of the wave shaper arms is controlled with the thyristors. This limits inrush current, overvoltage in capacitors and ensures that capacitors are charged adequately.
