% InputData_Net2 records the parameter of line,two/three windings transformer ,capacitor
% and bus.
% In this program,1 represents power transistion line,2 represents two
% winding transformer,n1 is higher voltage side and n2 is lower voltage 
% side of two winding transformer,3 represents three winding transformer,
% 4 represents capacitor,5/6/7 respectively represents PQ/PV/UA bus
