By use of eigenvalue analysis, the subsynchronous oscillation （SSO） characteristic of HVAC power system with series compensation capacitor and that of HVDC transmission system with supplemental subsynchronous damping controller （SSDC） are researched respectively. The mechanism of total subsynchronous damping conservation of HVAC power system with series compensation capacitor under variation of compensation degree as well as the mechanism of total subsynchronous damping conservation of HVDC transmission system with SSDC under the variation of amplification factor of SSDC are analyzed. Thus the law of subsynchronous damping variation under various oscillation modals is revealed.
