| 提出在基于电压源换流器的高压直流输电(VSC-HVDC)中采用多通道变参数的次同步附加阻尼控制(SSDC)来抑制次同步振荡的方法?在PSCAD/EMTDC中搭建了并联VSC-HVDC的IEEE次同步谐振第一标准测试系统,通过测试信号法得到在不同工况下发电机电磁转矩对调制功率的相位滞后特性,据此选择合理参数设计多通道变参数的SSDC?对并联VSC-HVDC的IEEE次同步谐振第一标准测试系统进行仿真表明,VSC加装多通道变参数SSDC后对次同步振荡有很好的抑制作用,并具有一定的鲁棒性? |

| Abstract: |
| Multi-channel variable-parameter SSDC (SubSynchronous Damping Control) is adopted in VSC-HVDC to suppress the SSO (SubSynchronous Oscillation). IEEE first benchmark system with VSC-HVDC is built in PSCAD/EMTDC. The phase lag property of generator electromagnetic torque behind modulating power is obtained with the test signal method,based on which,the rational parameters are selected for the design of multi-channel variable-parameter SSDC. Simulative results show that,VSC equipped with multi-channel variable-parameter SSDC effectively suppresses SSO with certain robustness. |
