| 摘要: |
| 基于实时性的要求，提出一种实时快速选择高效阻止失稳的切机地点的方法。按照发电机的有符号动能和功角乘积的大小在超前失稳机群中对可切机组进行排序，得到初始有效切机地点集合，通过计算等值机械功率切机前后的变化，剔除超前失稳机群中的被动失稳机组，得到最终的切机地点集合。IEEE 39节点系统和三华联网系统的仿真结果验证了所提方法的有效性。 |

| Abstract: |
| Based on the requirements of real-time performance，a method of fast generator-shedding location selection is proposed to efficiently prevent instability. The generators of the leading stability-loss group are sorted according to the product of its signed kinetic energy and power angle to get the initial set of effective generator-shedding location. The final set is obtained by removing the passive stability-loss generators from the initial set according to the difference of equivalent mechanical power between before and after generator-shedding. Simulative results of IEEE 39-bus system and Sanhua interconnected system verify the effectiveness of the proposed method. |
