摘要
本文用李亚普诺夫能量函数计算电力系统暂态过程能量临界值Ver,和在故障切除时能量函数值V(θc),若V(θc)≤ Ver,则系统稳定,反之是不稳定,可确定暂态稳定域.
By means of Lyapunov energy function we calculate the critical value Ver of the transient energy of power system and the value of the energy function V(θ)c when fault is cleared away. If V(θ)c≤Vcr, the power system is stable. Conversely, the power system is unstable and the region of the transient stability can be determined.
