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.
