Development of inductances, flux linkages, voltage equations, linear transformations, continuous simulation techniques and machine models. Digital modeling of linear and nonlinear power system components for electromagnetic transient studies. Methods of digital simulations of power systems in transient conditions, the traveling wave theory and protection against surges.
Why take this course?
This course supports and complements the available graduate study courses in Power Systems offered at Virginia Tech. Models of electric machinery, transmission lines, transformers and other components are necessary to conduct advanced research in power systems and to understand the results provided by advanced simulation packages such as the Electro-Magnetic Transient Program (EMTP) available today to the power industry.
