Calculate the capacitance C needed for the load compensation to unity power factor. Calculate the rms value E of the needed distribution voltage e before and after compensation. Calculate the active power loss (delta)Ps at energy delivery before and after compensation.
U = 2.4kV (line to ground), load has active power P = 120 kW at power factor = 0.6. Short circuit power at the bus is Ssc = 2MVA, and XstoRs ratio to the supply source impedance qual = Xs/Rs = 3. 3. The attempt at a solution  I'm not really sure where to start with this problem. I know how to find Rs and Xs using the formula for Zs, but I don't really know where to go from there. Please help me.
