Q#1 Transmission and Distribution GATE EE 2020 NAT +2 marks -0 marks

Bus 1 with voltage magnitude  is sending reactive power  towards bus 2 with voltage magnitude  through a lossless transmission line of reactance X. Keeping the voltage at bus 2 fixed at 1 pu, magnitude of voltage at bus 1 is changed, so that the reactive power  sent from bus 1 is increased by

20%. Real power flow through the line under both the conditions is zero. The new value of the voltage magnitude, , in pu (rounded off to 2 decimal places), at bus 1 is __________.
