Abstract :
The transient performance of an HVDC power system is highly dependent on the parameters of the current/voltage regulators of the power converter controls. In order to better accommodate changes in system structure or DC operating conditions, this paper introduces a new adaptive control strategy. The advantages of automatic tuning for continuous fine tuning are combined with predetermined gain scheduling in order to achieve robustness for large disturbances. Examples are provided for a digitally simulated back-to-back DC system
