Abstract
Способ контроля температуры проводов линий электропередачи с использованием температурного коэффициента α активного сопротивления проводов, отличающийся тем, что измеряют напряжение и ток в первом местоположении на линии электропередачи, измеряют напряжение и ток во втором местоположении на линии электропередачи, при этом измеренные напряжения и токи в первом и втором местоположениях синхронизированы по времени с возможностью совместной обработки указанных измерений напряжений и токов, по измеренным напряжениям и токам в первом и втором местоположениях определяют полное сопротивление линии электропередачи между первым и вторым местоположениями, из определенного полного сопротивления линии при температуре To проводов линии электропередачи определяют активное сопротивление Ro линии электропередачи между первым и вторым местоположениями, определяют текущее активное сопротивление R линии электропередачи между первым и вторым местоположениями и по известному температурному коэффициенту α активного сопротивления проводов линии определяют текущую температуру T проводов линии электропередачи по формуле T=To+(R-Ro)/(α·Ro). A method of controlling the temperature of wires of power lines using a temperature coefficient α of the active resistance of the wires, characterized in that they measure voltage and current at a first location on the power line, measure voltage and current at a second location on the power line, while the measured voltages and currents in the first and the second locations are synchronized in time with the possibility of joint processing of the indicated measurements of voltages and currents, according to the measured voltages and currents in the first and the torus locations determine the impedance of the power line between the first and second locations, from the determined impedance of the line at a temperature To the wires of the power line determine the impedance Ro of the power line between the first and second locations, determine the current impedance R of the power line between the first and second locations and the known temperature coefficient α of the active resistance of the line wires determines the current temperature T rovodov transmission line according to the formula T = To + (R-Ro) / (α · Ro).
