Analysis of Active Power Flow Control with Phase Shifting Transformer in AC Transmission Line

Nowadays, active power flow should be controlled because voltage fluctuation occurred on various load conditions. Phase shifting transformer PST is used to control the active power flow in three phase electricity transmission network. It can increase reliability and can serve as an alternative to new investments in overhead lines. The control of active power flow is achieved by adjusting the phase angle of the voltages at the PST terminals. In this paper, 230 kV AC transmission line is chosen for active power flow control. Two conditions, maximum and minimum load conditions are considered as a case study for active power flow control performance in a selected line. Simulation of active power flow with PST model is carried out by using Matlab software. Finally, according to simulation results, system voltages and active power depend phase angles are revealed in this paper.
