Anordning för eliminering av övermodulation i elanläggning

摘要

In a plant for transmitting electric power between a direct voltage network (1) and an alternating voltage network (4) through a station (2) members (14) are adapted to compare the amplitude of reference alternating voltage with the direct voltage on the direct voltage side of the station between the two poles of the direct voltage network and when the quotient reference alternating voltage amplitude/half of said direct voltage exceeds a predetermined value to send a signal to a control apparatus included in the station, which is adapted to interpret the receipt of such a signal as an order of increased consumption of reactive power of the alternating voltage side of the station and control a converter (6) in accordance with this order.
