| Abstract: | The significance of enhancing three defense lines in modern interconnected power systems is presented, the action principle and imperfection of conventional UFLS/UVLS criteria is deeply discussed, and the IEEE 39-node system and a practical power system in China are used to simulate to prove it. The result indicates the conventional criteria with global, dynamic, interactive viewpoints and means should be improved to keep the security and stability of power system under serious faults. |
