| Abstract: | Based on the eigen-analysis method for multi-machine electric power systems, the low-frequency oscillatory characteristic of the connected power networks of Huabei(including Shandong power network) and Huazhong(including Sichuan and Chongqing power networks) is studied by using the Power System Analysis Software Package(PSASP). Many low-frequency oscillatory modes are found, and the analysis of oscillatory mode-shapes for each oscillatory mode are also presented. The directional guidance is provided for installing and setting power system stabilizers in future. |
