A real-time simulation platform for power system operation

This paper describes the real-time digital simulation platform that can be used for power system operation, analysis, and power system modeling. This particular platform gives grid operators, planners and researchers the opportunity to observe how a power system behaves and can be used to demonstrate modeling, system disturbances of various types, and proper recovery actions, as well as to illustrate complex power system concepts. The Kundur power system consists of two fully symmetrical areas linked together by two 230 kV lines is modeled by using RSCAD in order to carry out simulations in real time. Various phenomena commonly encountered when dealing with the two-area system is studied. Despite its small size, it mimics very closely the behavior of typical systems in actual operation. The electromagnetic transient type of simulation made in RSCAD enables the study of fast and detailed phenomena like single-phase faults in the two-area network and to observe their effects on a larger time scale. Also, the case study of 16 bus system with 5 generators has been also used and the results are presented.
