Modern industrial customers, such as pulp and paper industries, have increased the vulnerability to power quality problems. A voltage source converter based high-voltage direct current (VSC-HVDC) transmission has the potential to offer high power quality when transmitting large amount of power. Therefore, in this paper, a VSC-HVDC transmission is proposed to supply such industrial plants in order to improve their power quality. The proposed VSC-HVDC together with an industrial plant is simulated in PSCAD/EMTDC to investigate the dynamic performance of the studied system during various operation conditions and after different events. Grid faults, different power production levels of the generator and trip of the generator are studied. Simulation results show that with a VSC-HVDC supply the power quality of industrial plants can be significantly improved. The extent of the improvement strongly depends on the VSC current limits, the generator power production levels and the generator ratings.
