“…At present, researches of the mixed-voltage quadruple-circuit transmission line system mainly focus on the short-circuit calculation of single-line faults or cross-voltage faults [5][6][7][8]. Analysis of the influence on relay protection caused by shortcircuit faults is relatively less [9][10][11], let alone the study of the effect on phase selectors.…”

“…The above algorithm can accurately solve the short circuit impedance of all nodes in the network without modifying the original admittance matrix, so as to realize the fast short circuit current scanning function. At present, the widely used short circuit current calculation software in the power industry include PSD-SCCP [9] , PSASP [10] , PSS/E [11] , etc. The horizontal comparison results of the functions between the above three software and FCAP are shown in Table 1.…”

With the continuous growth of load and the enhancement of grid structure, the problem of excessive short circuit current has become a key factor affecting the safe operation of the China Southern Power Grid. The comparison of measured data shows that the short circuit current calculation results of China Southern Power Grid are optimistic based on the existing short circuit current calculation method. It brings difficulties to the arrangement of the power grid operation mode. This paper first briefly introduces the calculation principle of the IEC60909 Standard (short for IEC60909 Short Circuit Current Calculation Standard). And based on this standard, an improved algorithm for short-circuit current calculation is proposed. FCAP (short for Fault Current Analysis Program), a newly developed software based on the improved algorithm, is compared with other similar software being popular in domestic and foreign to prove its engineering practical value.
