This paper studies modeling of Fossil-fuel plant, then gives an algorithm Short-circuit current calculated by computer; using Visual Studio C # programming language to develop a friendly interfaced software with data import and export modules, which can model several kinds of Fossil-fuel plants to made a calculation for the Short-circuit current at each node. Compared with the professional short-circuit calculation software, short-circuit current of periodic components, non-periodic components, thermal effects value are greatly matched. The calculated errors are almost within 5%. Meanwhile, the software is simple, efficiently implemented and has a wide range of adaptability which can be used in the construction of Fossil-fuel plants.
