A breaker-oriented, three-phase IEEE 24-substation test system

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 in-tended 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.
