Abstract
This paper analyzed the performance of two different controllers when unbalanced fault occurs in AC system and established a VSC-MTDC system with three terminals by using PSCAD/EMTDC.Vector current controller and dual vector current controller were applied separately under AC system unbalanced fault of active power control side.The simulation results show that dual vector current controller can improve the performance of VSC-MTDC under AC system unbalanced fault of active power control side.When the control strategy of eliminating the DC voltage oscillation is applied,the oscillation of DC voltage is effectively suppressed;and when the control strategy of eliminating the negative-sequence currents is applied,the negative-sequence of AC system is effectively suppressed.关键词
