A DC transmission system including wind turbine generating systems has been proposed and its steady-statecharacteristics have been analyzed. The proposed DC transmission system consists of wind turbine generatingsystems connected in series to a DC transmission line, synchronous machines, duplex reactors with whichharmonic components of the sending-end and receiving-end grid currents can be eliminated, a current-sourcethyristor inverter, and so on. The system has high reliability and it can generate high quality electrical powerwithout distortion and fluctuation. In this paper, in order to give generality to the results, average constants ofthe system are chosen and the effects of the duplex reactor inductances on the steady-state characteristics of aproposed DC transmission system having the average constants are revealed. It is shown that when the duplexreactor inductances are selected properly, the system can operate over a wide range without operation limit.
