Given data:
Voltage per phase, V = 3300 V
Resistance per phase, R = 2 Ω
Synchronous reactance per phase, Xs = 18 Ω
Generated emf per phase, E = 2195 V
To find: Maximum power developed by the motor
Calculation:
1. Impedance per phase, Z = √(R² + Xs²) = √(2² + 18²) = 18.44 Ω
2. The current per phase, I = E/Z = 2195/18.44 = 118.96 A
3. The power factor, cos(θ) = R/Z = 2/18.44 = 0.1084
4. The angle of the power factor, θ = cos⁻¹(0.1084) = 83.95°
5. Active power per phase, P = E*I*cos(θ) = 2195*118.96*0.1084 = 273.52 kW
6. Total power developed by the motor, P_total = 3*P = 3*273.52 = 820.56 kW
Therefore, the maximum power developed by the motor is 604.56 kW (option c).
