Integrative Program Research with Practical Short Circuit Calculation and Electric Equipment Selection

Abstrcat This paper analyzes the computer algorithm of practical short circuit calculation based on three-phase short and unsymmetrical short,and a kind graphic programming in power system is introduced. The research combines selection calculation of electrical equipment with electrical main connection and calculation of short circuit. The integrative program that is used to calculate short circuit current and to select electrical equipment is researched. based on database, expert system and electrical graphics. Short circuit calculation and electric equipment selection are completed in the graphical interface.The results are printed in the form of statement.
