摘　　要：分析了电网发生次同步谐振的机理及其对发电机的危害影响,介绍了各种抑制次同步谐振的方法,对其特点进行了比较。着重分析研究了阻塞滤波器的参数设计,对输电系统在大干扰故障情况下阻塞滤波器对次同步谐振的抑制效果进行了数字仿真分析。Generation mechanism of sub-synchronous resonance and its harm to generator are analyzed. Various methods for mitigating the sub-synchronous resonance are introduced as well as its characteristics are compared. The parameter design for blocking filter is emphatically analyzed ＆ studied. When large disturbances occur in transmission system, a digital simulation analysis on mitigating effect of the blocking filter on the sub-synchronous resonance is also made.
