| 摘 要： | 对复杂多机系统与HVDC相互作用引起的次同步振荡进行分析与抑制研究。采用机组作用系数法对不同运行方式下可能发生次同步振荡的机组进行了筛选。依据UIF不变的原则将复杂多机系统简化为单机交直流系统，利用复转矩系数法分析了系统的阻尼特性。将根据单机系统设计的次同步振荡阻尼控制器用于抑制复杂多机系统的次同步振荡，时域仿真结果表明了所设计的次同步振荡阻尼控制器的有效性。

| Abstract: | 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 ... |
