Abstract :
Two kinds of mechanism that cause Sub-synchronous Oscillation (SSO) by High Voltage Direct Current (HVDC) are introduced in this paper. The Unit Interaction Factor (UIF) and the test signal method are used to analyze SSO that caused by HVDC. The results show that when UIF>0.1, the simulation model takes the risk of SSO. Then, supplementary excitation damping controller (SEDC) is used to suppress the HVDC-SSO. The simulation results show that the SEDC designed has good damping effect on HVDC-SSO.
