FIELD: information processing systems, applicable at control of the electric power line on the basis of its adaptive model readjusted according to the current information on the power line electric parameters.
SUBSTANCE: the method consists in the fact that simultaneous determined are the current values of voltage 
and current 
respectively at the beginning and end of the line, each digital readout, both the present and the previous ones, are is conserved, then simultaneously determined are the reactive power at the beginning of the power line 
and the reactive power at the end of the power line 
and reactive quasi-power 
and 
then current reading of the signals are multiplied and determined their active power at the beginning of the line 
and the active power at the end of the line 
are determined, active quasi-powers 
and 
are determined, on the basis of which determined are the angles of divergence of vectors 
between voltage 
and current 
at the beginning of the power line, 
between voltage 
and current 
at the end of the line, as well as the angle of divergence of vectors 
between voltage 
at the beginning of the power line and between voltage 
at its end, and the angle of divergence of vectors 
between current 
at the beginning of the power line and between current 
at the end of the line.
EFFECT: simplified, enhanced precision and information content of determination of the current electric parameters of the power line.
