摘要
电力系统中持续的周期性小干扰可能引起系统的低频振荡。在介绍了小信号稳定的数学模型的基础上,提出了模式参与度的计算。最后通过实例仿真证明了小信号稳定模式参与度分析方法在实际电网中各种控制器的安装和配置等方面的有效性。
The low-frequency oscillation can be caused by periodical small disturbance in Power Systems.On the basis of the small signal stability model,the calculation of participation degree of the oscillation modes is proposed.Finally,the result of the instance simulation indicates the effectiveness of applying the participation degree analysis to the allocation of various controllers in actual power grid.
