Giovana — Protection and control Engineer

Worked as a contract engineer through Michigan Technological University during my Master Program in the Substation Design group performing transient analysis studies according to Xcel Energy's needs. Studies involved substation modeling in EMTP-ATP through CAPE database in order to evaluate switching transients such as capacitor banks and line reactors with or without surge arrestors, ferroresonance, resonance, inrush, outrush, back-to-back, voltage magnification and transient recovery voltage.

Worked on a project investigating different approaches in transformer modeling and their impact in the transient recovery voltage (TRV) parameters Modeled three different simplified transformer models and one Black-Box model in ATP Compared the models responses to a real transformer measurement readings Compiled final report with the results of the study as my Senior Design project

Worked on a project to verify in a very fast transient (VFT) study if the overvoltages caused by the first short-circuit led to the second short-circuit in the same fluoduct in a gas isolated SF6 substation (GIS). Computed ATP modeling of all the components of the substation in order to perform the study Interpreted the substation drawings in order to build the system model Analyzed the voltage waveforms to conclude and compiled final report with the results of the study
