This site is for doing nonlinear loadflow computation and
transient Simulation of high power networks with LTSpice
(use only for didactical purposes)

It is the first time one adapt a simulation program for electronic circuits
for doing nonlinear loadflowcomputation

All important elements are present like:

Voltage slacks
PV slacks
loads
transformers (with phase regulation)
petersencoils
shunt reactances
reactors
and many others
