In the following network, the voltage magnitudes at all buses are equal to 1 pu, the voltage phase angles are very small, and the line resistances are negligible. All the line reactances are equal to j1Ω
The voltage phase angles in rad at buses 2 and 3 are
1
θ2 = -0.1, θ3 = -2
2
θ2 = 0, θ3 = -0.1
3
θ2 = 0.1, θ3 = 0.1
4
θ2 = 0.1, θ3 = 0.2
