    摘要: In a plant for transmitting electric power between two stations (17, 18) through a direct voltage network (16) for High Voltage Direct Current an arrangement (23) is arranged for draining electric power from the direct voltage network. The arrangement has a valve (24) made of bidirectionally controlled thyristors (BCT) with ability to conduct current in both directions therethrough. The plant has also a unit (25) adapted to control the thyristors of the valve so that the current direction between the direct voltage network and the valve is such that electric power is fed from the direct voltage network to an alternating voltage network- connected to the valve independently of the power feeding direction between said two stations (17, 18).
