摘要：

To compensate the negative-sequence and reactive power in the electric railway traction power supply system, we proposed a novel railway power quality manage system based on V/v traction transformers (V/v-RPQMS). According to principle of proportional resonant (PR) controller, we proposed the control strategy of the V/v-RPQMS. In this method, the active and reactive current components in the vector control strategy are adjusted after transforming into a stationary coordinate to realize the V/v-RPQMS independent regulation of active and reactive power and the active power bidirectional transmission. Compared with the vector control using proportional integral (PI) controller, this strategy does not need repeated coordinate transformation but simplify the control algorithm; because no coupling term and feed-forward compensation exist, the robustness of the control system is improved. Finally, simulation and experimental results show that the proposed control strategy has a good dynamic and static performance, and it can significantly improve the grid-side power quality. ©, 2015, Science Press.
