Abstract :In this study, fault calculations in multi-phase power system (MPPS) are examined. Three-phase power system (3-PPS) and twelve-phase power system (12-PPS) are modelled. Analyzing faults in MPPS, symmetrical components method is used. Connection of sequence circuits for all fault types in 12-PPS are provided. Load flow analysis for MPPS is made by using phase coordinates method. It includes modeling of power systems components such as generator, transformer, and line for 12-PPS. Therefore, bus voltages are calculated before fault calculation. Different types of faults are calculated. Proposed fault calculation method for any type of fault at any bus of MPPS is provided. Fault calculations were done for all possible faults in 12-PPS. Symmetrical and asymmetrical fault currents in 12-PPS were calculated and listed. The fault location and type compared with other different locations and types of faults in 12-PPS. In addition, 3-PPS fault currents compared with MPPS examined in this study.Keywords : symmetrical fault, asymmetrical fault, fault analysis, symmetrical component, multi-phase power system, twelve-phase power system
