POWER SYSTEM DESIGN, SIMULATION AND ANALYSIS

Power system studies are performed for a variety of reasons. One of them is to ascertain whether the designed power system is fit for operation. For this purpose, many calculations need to be done by the electrical engineer. In most cases, the manual methods of calculation used in these studies are tedious and time consuming. To overcome this problem, a software solution should be used. The software should be able to perform the various calculations and studies besides providing a means to simulate the designed power system using a minimal amount of time. This project has two main objectives. The first objective is to study a model of an electrical power system in general. The power system is first designed using various guidelines from literature, Tenaga Nasional Berhad (TNB) and examples of existing power systems. To study this network, load flow and fault studies are performed using the ERACS software. The second objective of the project is to identify the major components of a power system and develop a software simulation program. Here, the MATLAB software is used. The major components identified are the synchronous generator, transformer and transmission line. It is possible to model them using the mathematical equations governing their behavior. The models of each component are combined to form the simulation program in MATLAB. The ERACS and MATLAB programs are then used to simulate several case studies. The results obtained are compared and discussed. During the course of the project, a full understanding of power systems and the main equipment associated with them shall be obtained. The methodology to be used in this project is outlined as follows: i) Conceptual design ii) Gathering of necessary data and manual calculations iii) Simulating and testing of the syste
