BASIC PRINCIPLES FOR THE DESIGN OF CAPABILITY CURVE • Capability ity curve of generator e with unsaturated sauaed magnetic cc circuit cu • Generator is sized to reach the nominal temperature at the rated values of (p n ) and (q n ) powers (the point R) i.e.: • for induct currents, i a = i an = Const., φ ≤ φ n , and • curve i f = Const. . and φ > φ n , i.e., q ≥ q R , with a reduced active power p ≤ p R Figure 2: Vector diagram of generator electromotive forces and the excitation currents (with corresponding scaling ratio)
