Transient Stability Improvement Of Power System With Phase Shifting Transformer

[Full Text]

Keywords: Phase-shifting transformer (PST), Transient stability, MiPower Software.



ABSTRACT: Transient stability of a power system is concerned with the system’s ability to remain in synchronism after the disturbance is cleared. Occurrence of a fault in a power system causes transients. The disturbances subjected to the system may be occurrence of fault, sudden change in load etc. This paper describes the improvement of transient stability with phase shift insertion by phase shifting transformer. A 3-phase to ground fault is created on the line to analyze the effect of fault and to find the critical clearing time. Then by inserting phase-shifting transformer, a series of simulations are carried out to find the appropriate angle of PST to achieve rotor angle stability using MiPower Software.
