Research on the integration of practical short circuit calculation and electrical equipment selection

electrical equipment;  Database;  Expert systems;  Practical short-circuit calculation

Based on the computer algorithm of practical short-circuit calculation of short-circuit current in three-phase short circuit and asymmetric short circuit, as well as the design method of power system graphics program, the calculation of electrical equipment selection is organically combined with the calculation of electrical main wiring and power grid short circuit, and the integrated program of practical short circuit calculation of power system and calculation of electrical equipment selection based on database, expert system and power system graphics is researched and developed. The short-circuit calculation and electrical equipment selection calculation of the program are carried out on the power system graphical interface, and the results are printed out in the form of a report.
