We have already proposed wind turbine generating systems connected in series to a DC transmission system with an externally commutated thyristor inverter. We have developed dynamic model for the proposed system and have analyzed dynamic performances of the system in detail. And we have proposed maximum power point tracking control system for the wind turbine generating system. Also, the steady-state characteristics of the system have been investigated. It has been shown that the system has high efficiency when the leading angle of commutation for the inverter is low. In this paper, we discuss the method of constantly controlling margin angle for the proposed system to obtain high efficiency and stabilization. The effects of constant margin angle control for the steady-state characteristics of the system are investigated first, and dynamic performances of the system for the case with the control system are explored.
