Engineering projects

A paper mill runs mixed GE, ABB and Allen-Bradley control platforms that have to keep production stable. Modify and validate the PLC logic and motor-protection settings, troubleshoot MCCs and VFDs up to 400 HP, and document the changes in AutoCAD for protection upgrades.

Inverter-dominated microgrids can't be tested safely on live hardware. Built and validated the OPAL-RT / RT-LAB real-time model and the Raspberry Pi + OP8666 DSP closed loop that let real controllers run against it. Co-author on a published Elsevier paper from the same research.

Utility and industrial clients needed 33/11 kV substations that stay safe under fault and lightning conditions. Produced the layouts and single-line diagrams, sized transformers and cables against ampacity, < 3% voltage drop and short-circuit withstand, and coordinated overcurrent protection to IEEE Std 80 and IEC 62305.

Moving bulk power ~200 km means trading conductor cost against losses, clearance and tower loading. Selected conductors, ran sag-tension calculations to set span geometry and ground clearance, coordinated insulation and planned towers, with a cost analysis alongside the technical case.
