This site is for doing nonlinear loadflow computation and
transient simulation of high energy networks with LTSpice
(it is dedicated for didactical purposes)

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

All important elements are present like:

voltage slacks
pv slacks
overhead lines and cables
transformers (with phase regulation)
shunt reactances
and many others especially for transient simulations like:
coupled lines
synchronous generators
asynchronous machines
star point builder transformers
surge arresters etc.
