Here, first current flowing in line is calculated first, then complex power flowing from bus 1 to bus 2 is calculated. From where, active power and reactive power flows per phase from bus 1 to bus 2 are calculated.

Here, S_12=-19.081+j*201.0199 KVA. Complex power flow is represented in magnitude form. If it is needed in polar form then S_12=201.9238<95,42 degrees KVA.
