Study on Fit Degree of the Short-circuit Calculation Based on BPA and National Standard

The national standard GB/T15544.1-2013 “Short-circuit Current Calculation of Three-phase AC System”, and the calculation method of short-circuit current commonly used in enterprises are briefly introduced. The fitting degree between the national standard and BPA program is analyzed, and it is considered that the BPA program can be consistent with the national standard by setting the calculation conditions of BPA and modifying component parameters, and the results are verified by an example. Finally, suggestions for setting up BPA procedures in enterprises are given in order to conform to national standard.
