专利汇可以提供CONTROL OF ACTIVE POWER IN A HIGH VOLTAGE DIRECT CURRENT TRANSMISSION SYSTEM专利检索,专利查询,专利分析的服务。并且A high voltage direct current transmission system has a first and a second converter station (STN1, STN2' respectively) coupled to each other via a direct current link (W1, W2), each converter station with a voltage source converter (CON1, CON2 respectively), and with voltage sensing means (M5, M6 respectively) for sensing at each of the respective converter stations their respective direct voltages (Udc1, Udc2 respectively). The first converter station has means (UdcREG, IREG) for voltage control of the direct current link by control of the direct voltage of the first converter station in dependence on a sensed instantaneous value thereof and a first voltage reference value (Udc1R). The second converter station has power control means for control of its active power flow (P2) in dependence on a reference value (P2R, f 2 R ) thereof. The power control means comprises voltage control means (UdcREG) for control of the direct voltage of the second converter station in dependence on a sensed instantaneous value thereof and a second voltage reference value (Udc2R), said second voltage reference value being formed in dependence on a third voltage reference value (Udc2R') and on a voltage reference correction signal ( DELTA UdcR) formed in dependence on a quantity (P2, f 2) indicative of the active power flow through the second converter station and the reference value (P2R, f 2 R ) thereof.,下面是CONTROL OF ACTIVE POWER IN A HIGH VOLTAGE DIRECT CURRENT TRANSMISSION SYSTEM专利的具体信息内容。
