Generator - P vs Q Loading

Generator active/reactive power split - maintains PF ≥ 0.8 lagging for export; voltage regulation adjusts Q.

Formula, assumptions, and limits

Genset nameplate at 0.8 lagging. Keep PF ≥ 0.85 to maximise active power headroom. Load sharing with other gensets: governor → P, AVR → Q.
