A private developer proposes to install a synchronous type generating plant connected to the local 11 kV network. If the generating plant produces 14 MW operating at 0.97 lagging power factor, calculate: (i) the reverse power flow into the transmission line during the peak loading conditions (11 kV bus is now the sending end) (ii) the corresponding per-unit voltage at the 11 kV busbar. If all factory loads are disconnected (e.g., due to a fault, or servicing) and if the generating plant continues to produce active power output of 14 MW, calculate the reactive power output of the generating plant required to keep the voltage rise at the 11 kV busbar within the statutory limit of +6 % of the nominal voltage.
