Title: " Dynamic Thermal Model for Different Size Trefoil Power Cables with Various Loads in Non- Forced Ventilated Tunnels".
Skills and Methodology: A complete thermal circuit model was developed for different size trefoil power cables
carrying various loads in non-forced ventilated tunnels (deep and shallow). The model directly computes conductor steady state ampacity, transient ampacity, load transfers, and temperature transients, and uses IEC standard 60287 heat source equations for the
power losses due to the skin and proximity effect and insulation. Many FEM simulations using COMSOL Multiphysics were completed to test and validate the model with the IEC standard 60853 and with reputable literature. MATLAB was used to solve the model iteratively to compare results with FEM.

MASTER'S THESIS
Title: "Time Domain Simulation of the Hysteresis Main Loop of Power Transformers".
Skills and Methodology: A circuit model was developed and implemented in EMTP to simulate the hysteresis main loop. Two open circuit experiments were performed on two actual transformers, one of hard-core material and the other of soft-core material. The open circuit data from each experiment was used to determine the magnetizing curve of each transformer. Data points along the magnetizing curve were taken to approximate linear inductances which were used to calculate circuit model inductors. These circuit model inductors were control switched as a function of flux and were used to model the nonlinear inductance and magnetizing curves. A nonlinear resistance characteristic was determined from the experimental data and was implemented in the EMTP circuit model to simulate the main hysteresis curve.
