This paper describes two methods to analyze any combination of simultaneous balanced and unbalanced faults in a power system. The first method can be used to calculate the symmetrical components and phase components for any bus voltage and branch current of a faulted power system. Using the second method, an equivalent network connected to the positive sequence network can be obtained. The specific features of mutually coupled lines are examined in the analysis of simultaneous faults. The computer implementation of these methods is based on the optimally ordered triangular factorization of the admittance matrix of the individual sequense network. The elements of the fault-port matrix of any simultaneous fault can be easily obtained without changing the admittance matrices of the original sequence networks which are still available to determine bus voltages and branch currents.
