Implementation of Unified Power Flow Controller (UPFC) for Power Quality Improvement in IEEE 14-Bus System
In this paper the performance of Unified Power Flow Controller (UPFC) is investigated in controlling the flow of power over the transmission line. This research deals with digital simulation of standard IEEE 14-bus power system using UPFC to improve the real and reactive power flow control through a transmission line by placing UPFC at the sending end using computer simulation. When no UPFC is installed, real and reactive power through the transmission line cannot be controlled. The circuit model for UPFC is developed using rectifier and inverter circuits. The Matlab simulation results are presented to validate the model.
