Re: LM324 based automatic voltage stabilizer circuit simulation

Am autotransformer is modelled as several inductors in series, paying attention to the “start” marker. Once the inductors are lined up, write one “K” directive, to define the coupling among them; typically, something like “K1 L1 L2 L3 L4 0.98”. The stray single winding is handled exactly the same way, and should be one of the L’s in the K directive.. Regarding the winding “start” indicator: It will not appear until there is a K statement referring to it, so you may need to flip polaraties after they are all placed and the K statement is in place. >> Exactly, well said Dave. I think I can do it here if necessary.

I might be wrong, but it looks to me like this circuit best provides a voltage boost. I guess there is one choice for voltage reduction. So, it might not be a good choice for handling an over-voltage situation from the mains supply.
>> It depends on how you sense the voltage at the input, is it HIGH or LOW, I will come with another circuit which might be meaningful.
I don't understand what you mean by "cut off" situation. What is "cut off"?
>>I do mean at low and high voltage compared to 220VAC( few % fluctuations) the load will be diss-connected from the system or it will be "on-hold" for a period.
