摘要： The invention relates to a valve (4) of a converter (2) of a high-voltage direct current transmission system having a plurality of valve sections (38), each comprising a plurality of thyristors (46) electrically connected in series, and a surge arrester (32), which is electrically connected in parallel to the valve (4). According to the invention, a surge arrester (58) is connected electrically in parallel to each valve section (38). Thus a thyristor valve of a converter (2) of a high-voltage direct current transmission system is obtained, which does not require control capacitors.

摘要： The invention relates to a system (1) for transmitting electrical power between a first and a second alternating voltage network (2, 3). A self-commutated converter (20) can be connected to the second alternating voltage network (2), said converter being connected to an unregulated rectifier (10) via a direct voltage connection. The unregulated rectifier can be connected to the first alternating voltage network on the alternating voltage side. The device according to the invention is characterised by a network generation device (9), which can be connected to the first alternating voltage network (2) and is provided for generating an alternating voltage in the first alternating voltage network (2), the network generation device (9) being designed to exchange reactive power and active power with the first alternating voltage network (2). The invention further relates to a method for stabilising a network frequency of the first alternating voltage network (2), in which the network frequency in the first alternating voltage network (2) is regulated by changing a voltage at the direct voltage terminal of the self-commutated converter (20).
