摘要
通过2个研究实例，对一般电力系统电压动态稳定性进行分析研究，应用分叉理论及映射原理，将系统雅可比矩阵特征复平面进行特定变换，从而寻求平衡解流形上动、静分叉点。研究分析系统电压从稳定到失稳乃至崩溃的发生发展过程，分析了励磁调节器的限制作用对电力系统动态电压稳定性的影响。实例结果验证了所提方法的正确性、有效性和实用性，并提出了一些新看法。
The power system voltage dynamic stability is studied by means of the new analysis method presented in part one of the paper with two practical examples. The bifurcation theory is used to search for the static and dynamic bifurcation points on the equilibrium solution manifold based on the power system dynamic models. Specific imaging transform is carried out on the system Jacobian matrix eigenvalue complex plane. The evolving process of the system voltage changing from steady state to instability and then to voltage collapse is studied and the effect of the limitation of excitation regulator on dynamic voltage stability of power system is analyzed. The results of the two examples demonstrate that the new method is correct. effective and practical.
