| 摘 要： | 在动态系统平衡点分岔现象的数值分析中，间接法是一个有效的算法。该方法的基本原理是，当动态系统参数缓慢变化时，在其平衡点的延拓过程中，首先检测该平衡点流形的局部邻域内系统的拓扑性质的改变，然后应用插值法来确定更高精度要求的参数分岔值。文中用间接法来确定电力系统非线性稳定分析中的平衡点分岔值，对一典型的电压稳定模型进行计算以确定系统负荷参数的fold和Hopf分岔值，并给出时域仿真结果。

| Abstract: | Am ong the num ericalm ethodsto analyze the localbifurcation phenom enaofdynam icalsystem , the indirectm ethod is an efficientone. Its basicprinciplesarefirstto locate thebifurcation values ofthe param etersin the continuation procedure of equilibrium of the dynam ic system and then by interpolation, to get the fine tuning ofthe value, as the param eters are quasi-varied. An indirect m ethod to analyze the bifurcation values for non-linear stability analysis of pow er system is designed. Itis applied to com pute the fold and Hopfbifurcation values ofa classicalvoltagestability m odel. The tim e dom ain sim ulation results arealso given and they show thattheindirectm ethod ispow erfuland robustto obtain the bifurcation values w ith satisfactory accuracy. This w ork is supported by NationalKey Basic Research SpecialFund (No. G19980203). |
