The application of the multi-loop method for AC electrical machines to the analysis of internal fault of generators, on which the developed software of internal fault analysis of generators is based, is described in this paper. The characteristics, user interface and structure of the software are introduced. In the software, the effects of air gap harmonic fields, various connections of windings, and spatial position of coils are considered. This software is capable of analyzing various types of internal and external faults, calculating all of the voltages and currents under different operating conditions, and combining the branch currents for the analysis of different protection schemes. This software, innovating the analysis of internal fault of generators and the design of main protection, is oriented to the design and setting of main protection scheme of large- and medium-capacity generators.
