Abstract

Способ измерения расстояния до места короткого замыкания в высоковольтных электрических сетях, заключающийся в измерении минимального значения вектора напряжения аварийного режима и определении отношения реактивной составляющей напряжения к току, отличающийся тем, что одновременно измеряют минимальные междуфазные векторные значения напряжений линии в различных точках и с использованием известных значений комплексных сопротивлений между этими точками определяют максимальные векторные значения разности фазных токов на этих участках, используя которых находят максимальную разность фазных токов поврежденного участка, расположенного в ближайшей окрестности точки короткого замыкания; определяют расстояние до точки короткого замыкания от ближайшей к ней точки измерения напряжения где протекает полученный ток. A method for measuring the distance to a short circuit in high-voltage electric networks, which consists in measuring the minimum value of the emergency voltage vector and determining the ratio of the reactive component of voltage to current, characterized in that the minimum interfacial vector values of line voltages are measured at different points and using known values the complex resistances between these points determine the maximum vector values of the difference in phase currents at these sites kah, using which they find the maximum phase difference of the damaged area located in the immediate vicinity of the short circuit point; determine the distance to the short circuit point from the voltage measuring point closest to it where the received current flows.
