应用于VSC-HVDC解耦和谐波抑制的控制策略
A kind of Control Strategy for VSC-HVDC System Decoupling and Harmonics Suppression
The VSC-HVDC system under the control of the normal internal model has the problems that decoupling effect of the active and reactive power is not ideal, dynamic performance needs to be improved et al. Thus, a kind of two-degree-freedom internal model for decoupling control of the VSC-HVDC system is made up, which is based on the normal one with a feedforward controller added in this paper. In allusion to the high harmonic content of the 5-, 7-, 11-, 13 order harmonics in the AC system of VSC-HVDC, a control strategy that two-degree-freedom internal model controller combined with the modefied repetitive controller was used to
