My name is Eduardo Lorenzetti Pellini. I’m an assistant professor (MS-3) for Escola Politécnica da Universidade de São Paulo. I had my graduation (2000), MSc (2006) and PhD (2010) in Electrical Engineering, in Power Systems. My alma mater is the Escola Politécnica da Universidade de São Paulo, precisely in the Electrical Energy and Automation Engineering Department, also known as PEA, for short.
Currently, I work with power system subjects which are, somehow, related to embedded electronics, control and automation engineering.
Since its creation around 2008, I work along the Power System Automation and Protection Research Lab - L•PROT or L.PROT or LPROT for short. Here I create hardware and software for new protection, automation and control (PAC) devices. Nowadays, I am working with IEC 61850 and IEEE 1588 standards for process bus applications.
The following sections tries to explain and presents details about my work as a power system engineer, embedded electronic designer, researcher and teacher.
More information about my academic achievements and interests can be found on my CNPq lattes curriculum.
From the day I got stung by Notion, I am trying to register most of my work and plans with it. Below I present some essays and drafts made with Notion.
In a daily basis, you will probably see me working with automation controllers, with microcontrollers and DSPs, in both hardware and software topologies, with FPGA synthesis, with educational kits, with software API’s, etc. In other words, some laboratory experiments where some “electronic thing” is connected to a power system device (a protection relay, a PAC, a new IoT sensor, a power converter, an electric motor, optic sensors with interferometry, and so on). I use tools like KiCAD, Altium, Tina Spice and other electronic design and simulation software.
However, I always worked with simulators, mostly real time ones, dedicated for hardware in the loop tests. I had developed my own simulators in the last twenty years, with both hardware and software specially designed for such. I've always sought to create alternative to professional tools, such as RTDS, SpeedGoat and National Instruments tools. But I must confess, RTDS is the best simulator I have ever seem.
Also I have deep emotions with data acquisition hardware and software, mostly those involving high speed networks as the communication media, such as Ethernet. Not only the data acquisition gathers my attention but the use of such data for ONLINE scientific visualization, using API’s such as OpenGL, and real time graphics. These tools usually help me to understand some complex (and invisible) phenomena, to debug something, but also, to create educational and teaching tools. Geogebra always caught my attention, but Im losing that ‘loving feeling’ recently. Today Im flirting with Processing, Mosquitto and Node-Red. However, I must confess, I worked before (and a lot) with MatLab, Octave, Scicos, Python and Labview in these scenarios. I am not a fan of any. Up to this day, I could not understand why Vissim (from Visual Solutions) did not endure the tides of time. It was pretty simple, fast and flexible, but got lost in the oblivion. I must try PLECS and PSIM in the future.
In Automation, recently I got involved with home automation and industrial automation with IoT and MQTT. But I worked for more than 20 years in contact with industrial automation and electric drives, with 61131, 61499, Modbus, IEC 61850, Ethernet/IP and other protocols.
I also like 3D printing and 3D modeling. For these, I found myself comfortable using Solvespace, Marlin, Slic3r and tools like Octopart/Raspberry PI. I have learn how to hack and adjust 3D printing firmware, to create custom printers.
Linux is good, but every time I understand its guts, I dont. But probably this is why Im always trying to learn something from it. If you want to get my attention, show me your skills with real time threads, raw ethernet, and general linux programming (Qt for user interface, please).
I use Windows because everybody uses Windows. Agent Ransack - 7-zip - VLC - WinMerge - Hexplorer - TeraTerm - Octave - VSCode - Platformio - KiCAD - Solvespace - Xournal++ - OpenBoard - TexStudio - MikTex - LibreOffice.
Stock firmware is the worst firmware. Hack your things! Have fun while voiding warranties.
