This is the companion lab to EE 335 Power Generation, Transmission & Distribution which is a compulsory course for EE students. The development of electrical power systems has immensely contributed to the technological advances of the humankind over the past century. Electrical power provides clean and convenient energy to the modern society, which is necessary for the realization of the luxuries we are enjoying in this world today. In summary, the modern world and society does not exist without the availability of electricity. To study and analyze the large scale power systems remains impossible without the help of software tools. With the advent of computer aided tools, now it is possible to model and design large power systems and analyze their performance even before they are built. For expansion of existing power systems as well, the changes in power systems are first simulated and then applied. Through the labs of this course, students will be introduced to the application of software for modelling and simulating power systems and its components. Students will be utilizing software which include MATLAB Simulink and PSS®E Xplore which is a power specific software used in industries. This will reinforce the concepts learnt in theory classes.
