Question

Construct the performance chart for a 7500 kW, 0.8 pf, 9375 kVA, 2.4 kV

synchronous generator. The generator has a synchronous reactance of XS

= 0.7 Ω/phase, and the maximum excitation is 2.0 pu. The maximum rotor

angle for safe, stable operation is 60°.

Explain how correct scaling of the chart is achieved and clearly indicate all

operating limits. Use the chart to determine the excitation and the rotor

angle at full load, i.e. 7500 kW, 0.8 pf lag.
