| Notes | HVDC; subsynchronous oscillation; damping characteristic; simulation 41-1401/TM Subsynchronous oscillation resulting from the interaction between complex multi-machine system and HVDC is analyzed and damped.Firstly,the turbine generator units that have SSO problem are screened out using unit interaction factor method.Then,the complex multi-machine system is simplified into single-machine AC-DC hybrid system according to the principle of UIF invariability and the damping characteristic of AC-DC hybrid system is analyzed by complex torque coefficient method.Finally,the HVDC supplemented subsynchronous damping controller designed for single-machine system is used to damp the subsynchronous oscillation of the complex multi-machine system and the simulation results indicate that the SSDC designed in this paper is effective.
