Study of UPFC Location for Installing in Power System to Control Power Flow

摘要

This research studies the effect of location of Unified Power Flow Controller (UPFC) on power system. In this study the several case studies including various points for installing UPFC on power system are considered and results of profile of voltage at all of buses of system is obtained. The active and reactive of all transmission lines of power system following installing UPFC at various points of system is discussed and results are analyzed. The encouragement to the construction of HV lines, the amount of power transmission/km on HV line and the amount of power transaction as seen from economic side is much responsible for concern towards congestion in power system. The solution is the use of FACTS devices especially the use of UPFC. In this research the study of UPFC with its various candied locations for installing on power system is understood. Second, the operation of control system used in its converters is also studied. Finally by help of modeling of a power system in MATLAB/SIMULINK, and by installing UPFC in transmission link, its use as power flow controller and voltage injection is seen. Conclusion is made on different results to see the benefit of UPFC in power system.
