FIELD: electric engineering, possible use in electric transmission line.
SUBSTANCE: in the method for determining current parameters of electric mode of power line for construction of its T-like adaptive model, instant current and voltage values are measured at the beginning of the line and synchronously via communication channel instant values of current and voltage at the end of line are measured. Resulting arrays of instant values of current and voltage in the end of line are transferred to the beginning of power line via communication channel. Count arrays of instant current and voltage values at the beginning and the end of the power line are produced in one and the same time moments with equal step. In loading mode in blocks for computing active and reactive resistances of power line losses of reactive powers are determined on longitudinal reactive resistances, active and reactive resistances of longitudinal branches of electric transmission line, representing an area of possible solutions of longitudinal branches of T-like adaptive model for distributed values of longitudinal voltage drops. In the block for computing transverse active and transverse reactive resistances, losses of active power are determined at transverse active resistance and active and reactive resistances of transverse branch, representing an area of possible solutions of determining of parameters of transverse branch of T-like adaptive model for distributed values of longitudinal voltage drops. Longitudinal and transverse active and reactive resistances of power line are determined in idle running mode. For the value of coefficient k=1 actions are repeated in load mode and total values of active and reactive resistances are determined. On basis of resulting values of resistances of longitudinal and transverse branches for load and idle running modes, values of resistances of longitudinal and transverse branches of T-like adaptive model are determined.
EFFECT: simplification, increased precision and informative value when determining current parameters of power line.
