Abstract
Способ определения места повреждения линии электропередачи путем фиксации момента повреждения, измерения напряжений и токов основной гармоники аварийного и доаварийного режимов выделении аварийных составляющих измеренных напряжений и токов, преобразования измеренных величин и их аварийных составляющих с использованием образованных напряженческих и токовых моделей линии в напряжения и токи мест предполагаемого повреждения, отличающийся тем, что токи и напряжения, наблюдаемые в конце ветвей схемы линии с многосторонним питанием, используя модели ветвей линии, пересчитываются к их предполагаемым значениям в узле схемы, по результатам расчетов выбирается поврежденная ветвь и относительно нее остальная часть схемы эквивалентируется, в результате последовательных преобразований линия с многосторонним питанием сводится к линии с двухсторонним питанием, в которой имеется место повреждения, далее место повреждения определяется по модели получившейся линии. The method of determining the location of a power line damage by fixing the moment of damage, measuring the voltages and currents of the main harmonic of the emergency and pre-emergency modes, highlighting the emergency components of the measured voltages and currents, converting the measured values and their emergency components using the generated voltage and current models of the line to the voltage and currents of the places damage, characterized in that the currents and voltages observed at the end of the branches of the multilateral power line circuit are used Using the model of the branch of the line, they are recalculated to their expected values in the circuit node, the damaged branch is selected according to the calculation results and the remaining part of the circuit is equivalent with respect to it, as a result of successive transformations, the line with multilateral power is reduced to the line with two-way power, in which there is a damage, then the place of damage is determined by the model of the resulting line.
