The reactance stores energy and delivers it later. Why
are you having so much trouble with that age-old concept?


Show me the reactance and its power function of time such that
it stores and releases the energy at the correct time.


I don't have time to teach you AC circuit theory which
you really do need to understand. The power function
for the reactance is of the same form as it is for a
resistance, i.e. V(t)*I(t). I haven't seen you include
that reactance power function anywhere. When you do,
you will find your "missing" power and balance your
energy equations.

The reflected energy that is not dissipated in the source
resistor at time 't' is stored in the reactance and dissipated
90 degrees later. Until you choose to account for that time
delay, your energy equations are not going to balance.


I see no reactance that performs this function.


Please go take an AC circuits course. That's exactly
what a reactance does. The source terminals see +j44.1
ohms of reactance looking into the transmission line.
