Abstract

This undergraduate project intends to realize the modelling and computational implementation of the FACTS TCSC device to be coupled to the Current Sensitivity Model (CSM) of the single machine-infinite bus power system - SMIB system. Therefore, the TCSC is going to be represented by current injections.The objective of the modelling is the performance study of the electrical system face to small signal stability by simulations. This way, the models and the synchronous machine and any controller are linear.The CSM that is used in this work is an alternative to the classical Heffron &Phillips Model and also to the Power Sensitivity Model (PSM).During the project firstly is going to be considered the TCSC device and the respective current equations will be described. As the objective is the study of small signal stability, these equations will be linearized around an equilibrium point. In the sequence the modelling obtained to the TCSC is coupled to the CSM to the SMIB system.For the simulations of the electrical system, the computational implementation is going to be in MATLAB software. This choice is due to be easy to program and the knowledge of the candidate.Results will show a better comprehension of the problem and the conclusions will be discussed.This project is for one year.
