railway RRB JE (CBT I + CBT II) Mock Test 2024 Power Systems Load Flow Studies Classification of Buses
Two buses in a system are maintained at the voltages V1 = 1.25 ∠30° and V2 = 1.35 ∠25°. Bus 1 and Bus 2 are interconnected by a transmission line of impedance (1.3 + j 7) Ω. If the load is pure inductive load, the power flow direction is
1
Real power flows from Bus 1 to Bus 2
2
Real power flows from Bus 2 to Bus 1
3
No real power flows between the buses
4
Reactive power flows from Bus 1 to Bus 2
