Accurate Electrical Fault Detection in the Permanent Magnet Synchronous Generator and in the Diode Bridge Rectifier of a Wind Energy Conversion System

This project develops and tests a symmetrical‑component diagnostic method that can find, isolate, and tell apart different electrical faults in a small wind‑energy conversion system (WECS). It concentrates on two important problems: * A short circuit between turns of the stator winding in the permanent‑magnet synchronous generator (PMSG). * An open‑circuit diode in the three‑phase diode‑bridge rectifier that follows the generator. The method builds an analytical model of the negative‑sequence voltage and derives new equations that describe how the system behaves when it is healthy and when it is faulty. By looking at how selected fault indicators change with load and speed, the approach creates a reliable way to detect

the faults. Students will model the WECS in a simulation tool, check the derived negative‑sequence voltage equations, and test how sensitive the fault indicators are. This gives a clear, step‑by‑step path for exploring advanced fault diagnostics in renewable‑energy equipment and for comparing the analytical results with simulated or experimental data.
