The initial rotor angle of 60 degrees refers to the phase angle difference between the generator and the transmission line. This angle is important to determine the power flow and stability of the system.

Assuming a balanced system, the power flow in the transmission line can be calculated using the power formula:

P = V1 * V2 * sin(delta) / X

Where:
P = Power flow (in watts)
V1 = Voltage at the generator (in volts)
V2 = Voltage at the transmission line (in volts)
delta = Rotor angle difference (in radians)
X = Reactance of the transmission line (in ohms)

Given:
MVA = 100 MVA
Frequency = 50 Hz
Generator voltage = V1
Rotor angle difference = delta = 60 degrees

To calculate the power flow, we need to know the voltage at the transmission line (V2) and reactance of the transmission line (X). Without this information, we cannot determine the exact power flow.

Please provide the voltage at the transmission line (V2) and the reactance of the transmission line (X) for a more accurate calculation.
