Self-consistent models of nonideal plasma

The theoretical aspects of constructing of models of plasma nonideality are reviewed. To describe plasma system one must choose the model correction $\Delta F$ for free energy as well as way of statistic sum's restricting. These factors usually considered as independent each other untill nowadays. That is why the method of constructing of such factors from single principle is offered. There is analitic procedure created, which allow us to find $\Delta F$ according to the statistic sum's cutting. Also the results of appliement of this approach are briefly described: the model $\Delta F$ was derived from modern theory of micro-field character of interaction in plasma.
