摘　　要：介绍了电厂设计中短路电流计算的基本步骤:包括基本参数的描述、电路元件标么值的计算、短路点短路电流的计算;并介绍了短路电流的计算方法:如基准值的选取、短路阻抗标么值计算、等值阻抗图的简化等。通过短路电流计算的基本步骤和计算方法的介绍使电气设计人员对纷繁复杂的短路电流计算有了清晰的思路和可靠的方法,解决了电气设计人员在短路电流计算时无从下手的困难。The article introduces the process of the short-circuit current computation in the power plant,the process includes the description of the basic parameters and the computation of the circuit components about per-unit value and the computation of the short-circuit current in the short dot. This article also indicates some methods about the short-circuit current computation, for example the selection of the base value and the computation in of the short current impendence about the per-unit value and the simplification of the equivalent impedance drawing and so on. By introducing the processes and the methods of the short-circuit current computation in order that the electrical engineering design draft person can have the clear thread and the dependable way when he faces the complicated computation in of the short-circuit current, simultaneously the article is helpful for the electrical engineering design draft person because it solves the intricacy difficulties about the short- circuit current computation in.
