In this paper, a steady-state model of a VSC (voltage source converter) based HVDC system has been developed. According to this model, the corresponding relationship between the two controlling and the two controlled variables of the VSC is determined. Furthermore, a nonlinear control strategy combining an inverse model controller with a PI controller is proposed, and a nonlinear compensation method is adopted for the DC voltage PI controller. Digital simulation shows the validity of the established steady-state model and the feasibility of the proposed control strategy.read more

TL;DR: In this paper, a DC/DC-converter is connected to a first of the poles of the direct voltage side of the converter and through a first output terminal connected to one of the current valves to the second of poles so as to obtain an unbalanced step-up-transformation of the voltage between the two poles while obtaining a potential having a higher value on the second output terminal than on said first output terminals.
