Power Systems and Illumination

Study lessons

1. 1

   Transmission, Per-Unit, and Fault Analysis

   Covers generation basics, transmission and distribution line behavior, the per-unit system, and symmetrical fault analysis, the computational core of the REE power-systems subject group.

3. 3

   Power Generation

   Covers the sources of electric power and their prime movers, the synchronous generator, base load versus peak load, and the four generation factors (demand, load, capacity, and diversity) with exact worked computations.
