Abstract :
Techniques have been developed to permit the response of the controls for DC transmission systems to adapt to large system changes. A gain scheduling approach tunes the control as an on-line function of the effective short-circuit ratio and contingency indicators. The method has been tested by digital simulation, based on EMTP, of a back-to-back DC system. It has been found to be robust and control performance has been enhanced
