Abstract

The voltage source converter based high voltage direct current transmission (VSC-HVDC) supplying passive networks is subject to voltage quality problem. In this paper, based on analyzing the influence of time delay introduced by PWM inverter and computation, a delay compensation method for vector control method is proposed to improve the control dynamic and therefore enhance the voltage quality. Simulation results are obtained from PSCAD/EMTDC under different operation conditions. The comparison of the behavior between the proposed control method and the conventional method clearly shows the proposed control method can improve the voltage quality during the load changing and AC grid fault.
