Accurate bus-oriented, three-phase modeling of power systems is desirable for advanced applications and has become practical due to increased computational capability. To assist research activities in this area, this paper presents a benchmark three-phase test system. The proposed system is based on the 24-bus IEEE Reliability Test System that has been converted into a 24-substation, breaker-oriented, three-phase model. The model is available in electronic form at the site: http://pscal.ece.gatech.edu/testsys/. The proposed model is intended for use in research for three-phase power flow analysis, reliability analysis, fault analysis, transient stability, evaluation of fault currents through specific breakers, risk assessment of breaker failures, and other applications.
