MMC-HVDC circulating current suppression method based on improved proportional resonance control
The circulating component existing between the three-phase bridge arms of the modular multilevel converter(MMC) can not only affect the stable operation of the converter, but also increase the loss of the system. In order to suppress the circulating current, a MMC circulating current suppression met...

| description | The circulating component existing between the three-phase bridge arms of the modular multilevel converter(MMC) can not only affect the stable operation of the converter, but also increase the loss of the system. In order to suppress the circulating current, a MMC circulating current suppression method based on improved proportional resonance (IPR) control is proposed in this paper. The second and fourth harmonic components in the circulating current are extracted by the notch filter. After the harmonic components are suppressed by the improved proportional resonance control, the voltage compensation is obtained to compensate the modulated wave signal. The control structure of this method is simple and the control effect is good. Finally, a simulation model was built in PSCAD/EMTDC and the proposed control method is simulated, which verified the correctness and feasibility of the scheme. |
