Fault analysis in multi-phase power systems considering symmetrical components and phase coordinates methods. Journal of Engineering and Technology, 3 (1), 42-60.2619-9483https://hdl.handle.net/20.500.12402/2265In 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. It includes modeling of 12-PPS components such as generator, transformer, and line. In order to analyze faults in MPPS, symmetrical components method is used. Load flow analysis in MPPS is made by using phase coordinates method. Proposed fault calculation method for different types of faults such as single line, single line to ground, two line to ground, etc. are provided. Fault calculations were done for all possible faults in 12-PPS. All 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.eninfo:eu-repo/semantics/openAccessAttribution-ShareAlike 3.0 United StatesSymmetrical FaultAsymmetrical FaultFault AnalysisSymmetrical ComponentMulti-Phase Power SysteTwelve-Phase Power SystemArticle314260
