We have already proposed a wind turbine generating system connected in series to a DC transmission system with an externally commutated thyristor inverter. Also, Dynamic performances of the proposed system have been analyzed in detail. It has been shown that the output power of wind turbine generator can be kept almost maximum value and the output active power of the whole system can be controlled for the case with the power control systems. In this paper, the steady-state equations of the proposed system are developed first, and steady-state characteristics of the system are investigated. Also, the relations between the output power of the whole system and leading angle of commutation for the inverter for the various DC input voltages are studied. It is shown that the system has high efficiency in the case of high DC input voltage. Finally, dynamic responses of the system in considering steady-state operating values when wind speed is changed are explored.
