Transformer of my Power Supply in LTpsice
The only significant figure for simulating that sort of power supply is the transformer leakage inductance, which will range from negligible to very negligible. 

You should assume a figure of 0, which will mean that the peaks of inductor current will be limited only by the winding resistance of the transformer (much easier to get a real figure for that, measure with a meter, then double it for the effect of the primary as well), and the residual resistance of your bridge rectifier diodes.

As you allow the leakage inductance to rise (try figures of 1uH, 10uH, 100uH etc in your simulation), you will find the peaks of rectifier current become slightly less in amplitude, and slightly longer. Basically good things. But you need to design for zero, which is worst case for current peaks.

The transformer has other defined inductances of course, primary and secondary inductance. However, the primary inductance only defines the magnetising current the transformer takes from the supply. The secondary inductance is short-circuited by the primary and the supply connection, and so does not appear in the output. To the extent that the secondary inductance is not 100% short-circuited by the primary, that's the little bit of leakage inductance left over!
