A generalized methodology based on symmetrical components for multiple-fault calculation in power systems

• This article presents an efficient computational method to solve the problem of simultaneous multiple faults in power systems, using a conventional symmetrical component formulation. The methodology made possible the development of a programming routine, which takes into account a generic set of boundary conditions for almost any type of fault or combination of faults that can occur simultaneously, involving any number of phases. The program was tested with IEEE 14-, 57-, 118-, and 300-busbar benchmark systems facing up to ten simultaneous series and shunt faults. The results were satisfactorily tested against classical three-phase formulation solutions.
