This paper develops the dynamic equivalents program combined with graphic user interface(GUI), to solve the stability of large power system. The proposed method is coherency-based dynamic equivalents for transient stability studies. The program also provides with pull-down menu and Hangeul help information for users. The developed dynamic equivalents program is suitable for the transient stability studies of a large power system with lots of data. The dynamic equivalents demonstrated over the New England system with 39 buses and 10 generators.
