| 摘要: |
| 通过计算模式阻尼比对机组有功出力和直流线路有功功率的灵敏度，得到参与振荡模式的关键机组和直流线路。提出基于阻尼比灵敏度的由机组出力调整和直流传输功率调整两部分组成的混合控制策略，以此抑制大区域电网的区域功率振荡。在软件DIgSILENT中搭建了8机交直流电力系统，通过策略实施前后的结果对比，表明所提控制策略能够有效地抑制交直流电力系统的区域振荡，提高了系统的稳定性。 |

| Abstract: |
| The sensitivity of mode damping ratio to generator active power or DC line active power is calculated to obtain the critical generators or DC lines participating in the oscillation mode，based on which，a hybrid control strategy consisting of the generator power output regulation and the DC power transmission adjustment is proposed to suppress the areal power oscillation of large power grid. An 8-generator AC-DC power system is built in DIgSILENT and the simulative results are compared between with and without the implementation of the proposed strategy，which shows that，with the proposed strategy，the areal oscillation of AC-DC power system is effectively suppressed and the system stability is enhanced. |
