													    | Abstract  In order to reduce the impact of short-circuit faults on electrical equipment, two methods are used to calculate the short-circuit current of the power supply and distribution system of 18-roll project, and compares the two calculation methods in this paper. It provides a reliable theoretical basis for the subsequent design of the project, and also provides a strong guarantee for the safe and stable operation of the power supply and distribution system. |
