Hello! I'm Raymund

I am a passionate electrical engineer and fitness fanatic

I've graduated from the EDP rotational program and will begin working in the Operations Analysis department where I will be analyzing generator-related things such as frequency disturbances and ancillary services.

Outside of work, you can probably find me climbing at Austin Bouldering Project.

PROJECT PORTFOLIO

Dynamic Simulation of EMP

Dynamic Simulation of HEMP

This video is a side-by-side comparison of two dynamic studies in which an HEMP was applied to a 10,000 bus synthetic grid. The only difference between the two simulations is the ground conductivity model used to calculate the HEMP electric field. The video clearly shows that the uniform model yields more severe impacts to the grid's voltage stability.

The HEMP electric fields used in this video were calculated using a tool I developed using MATLAB.
