Abstract
A voltage-source converter, VSC, control system including an active damper, AD, a direct-voltage controller, DVC, and an alternating-voltage controller, AVC. The VSC control system is configured to control a VSC. The AVC is configured to regulate, using an integrator, an ac-bus voltage of the VSC by calculating a q component of a current reference vector for the VSC. The DVC is configured to regulate, using an integrator, a dc-bus voltage of the VSC by calculating a d component of the current reference vector. The AD is configured to amplify a vectoral difference between the ac-bus voltage and a corresponding reference, and to add the q component of the amplified vectoral difference to the q component of the current reference vector and to an input of the integrator of the AVC.
