Anlage zur elektrischen Kraftübertragung, mit Gleichspannungsreglung

摘要

In a plant for transmitting electric power between a direct voltage network (1) and alternating voltage networks (6-9) through VSC converters (10-13) the stations (2-5) for transmitting electric power have regulating apparatuses (14-17) adapted to enable regulation of either voltage or current. Means (18-21) are arranged for measuring the direct voltage, and members (22-25) are adapted to compare the direct voltage measured with a predetermined value and when this is underpassed send signals to the respective apparatus for changing regulation mode, so that a change of the voltage-regulating station takes place.
