Power Systems & Power Quality Labs
Three-phase loads, power factor correction, transformer characterization and rectifier harmonics, measured on the bench and analysed in MATLAB.
A series of hands-on power labs covering balanced and unbalanced three-phase loads, power factor correction, single-phase transformers and diode rectifiers, with MATLAB used to extract phasors and harmonics from measured waveforms.
Highlights
- Characterized wye- and delta-connected RL loads, including neutral-point shift, and verified the two-wattmeter method to within 1%
- Power factor correction cut reactive power from 20.5 to 2.7 VAR (87%) and source current from 1.50 to 1.14 A at constant real power
- Extracted a transformer equivalent circuit from open- and short-circuit tests and captured inrush transients
- Measured 2.6% output ripple for three-phase vs. 13% for single-phase rectification; wrote least-squares phasor and Hann-windowed FFT scripts
