Abstract
A power conversion system includes: a self-commutated converter connected between an AC power system, and a first DC main line and a DC return line; a line-commutated converter connected between the AC power system, and the DC return line and a second DC main line; and a control device. When activating the self-commutated converter and the line-commutated converter, the control device activates the self-commutated converter, and after completion of activation of the self-commutated converter, activates the self-commutated converter. The self-commutated converter can be activated first to take advantage of a function of the self-commutated converter that is not included in the separately-commutated converter.
