Transient stability analysis of single machine infinite bus with different power system stabilizers

Abstract

Stability analysis is the process of testing for robustness or weakness of a system undergoing a certain disturbance. It is based on the modeling of power system components such as the synchronous generator, the transmission lines network, and the power loads on the receiver side. The model under investigation is the single machine infinite bus (SMIB); so that its stability be maintained, modeling an excitation system as well as a power system stabilizer (PSS) are to be assessed and applied as well. The linear model corresponding to the SMIB circuit is known as the Heffron-Philipps Model (HPM) or the K-parameters model. This can be obtained after linearizing the equations of the basic system around the operating conditions. In this paper, SimPowerSystems toolbox of Simulink is used to generate a circuit of the SMIB system, and then several faults are to be applied to it. Then, the response of the system and its stability are studied after applying different PSS designs.
