A power system is considered to be transiently stable if it can regain and maintain synchronism after a sudden disturbance. Circuit breakers play a pivotal role in maintaining transient stability of power systems. Using high speed circuit breakers, transient stability can be achieved efficiently in power systems. The project has aimed at the improvement of the transient stability using high spe...

The effect of line impedance compensation mode of series inverter along with the voltage regulation mode of shunt inverter of UPFC is investigated for transient stability improvement of Single Machine Infinite Bus System. Four control modes like perpendicular voltage or phase angle control etc have also been discussed. The effect of line impedance mode on critical clearing time with a three pha...

This paper presents the design of a non-linear controller to prevent an electric power system losing synchronism after a large sudden fault and to achieve good post fault voltage level. By Direct Feedback Linearization (DFL) technique robust non-linear excitation controller is designed which will achieve stability enhancement and voltage regulation of power system. By utilizing this technique, ...

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 t...

Abstract: This paper presents a new approach to perform time simulation of power system transient stability using implicit quadratic integral method. Fast and reliable simulation of the transient stability is required to achieve high reliability based on the online stability assessment. The trapezoidal method has been mainly adopted for this purpose. However, the proposed method shows the possi...

with increasing the presence of microgrids (mgs) in the power systems, investigating the mg stability during transient faults is necessary. this study investigates the transient stability analysis of a mg supplied by multiple inverter interfaced distributed generations (iidgs) during fault. the transient stability of a mg is highly depends on the iidgs control strategy. a mg, simulated on matla...
