PMGs’ offer of high performance is brought into sharp relief under “partial load” — the most common operational state, due to the inconsistent nature of the wind — where they have demonstrated efficiencies of up to 98% in blustery conditions, and energy production yields as much as 8.5% greater than the double-fed induction generators that currently dominant.
At the European Wind Energy Association’s annual conference in Brussels last week, the industry’s growing faith in PMGs was in evidence.
