Protection Setting Verifying And Analysis System Of Sub Power System

Necessities and methods of verifying protection setting are presented in this paper. Requirements analysis, system frame design, algorithm design, code compile and software test of protection setting verifying and analysis system of sub power system are all accomplished. Main research work of this paper is concentrated on three respects: (1) Knowledge expressing of mathematic model and physics model of power system using relation database and Object Oriented language, (2) New methods of in-substation topology and net topology analysis based on topology of hierarchical model, (3) Father research of protection coordination considering difference of protection setting verifying and fixing.Yu Zhe(Power System and Its Automation)Directed by prof.
