The invention discloses a power system fault calculation result calibration method. According to the power system fault calculation result calibration method, whether power system fault short-circuit fault calculation has problems or not is calibrated and identified through overall process calibration according to different circuitry principle, the overall process calibration comprises electrical power system primary equipment parameter calibration, electrical power system circuit and primary equipment connection model calibration, electrical power system model calibration and short-circuit calculation calibration, a short-circuit calculation portion is verified through a power system fault calculation result based on the Kirchhoff's laws, and overall process closed loop management of short-circuit fault calculation is achieved.
