Abstract

1. Способ определения вида и места повреждения линий электропередачи класса 10 кВ с изолированной нейтралью, включающий результаты расчетов в фазных координатах параметров аварийных режимов фидеров 10 кВ, фиксирующие приборы и передачу оперативной информации в виде их показаний с целью сравнения их с расчетными значениями и вычисления расстояний до повреждения, отличающийся тем, что в качестве расчетных и измеренных параметров аварийного режима используют три фазных напряжения в начале линии, три фазных тока в начале линии, а также два напряжения на реагирующих органах фильтров обратной и нулевой последовательности, подключенных через измерительный трансформатор.2. Способ по п.1, отличающийся тем, что производят расчет аварийных режимов с учетом влияния: несимметрии собственных и взаимных сопротивлений фаз линии, пофазно-отличной нагрузки, параметров трансформаторов, переходных сопротивлений, мощности и тангенса угла нагрузки, статических характеристик нагрузки.1. A method for determining the type and location of damage to power lines of class 10 kV with isolated neutral, including the results of calculations in phase coordinates of the emergency conditions of 10 kV feeders, fixing devices and the transmission of operational information in the form of their readings in order to compare them with the calculated values and calculate distances to damage, characterized in that as the calculated and measured parameters of the emergency mode, three phase voltages are used at the beginning of the line, three phase currents at the beginning of the line, and two voltage on the reacting bodies of the filters of the reverse and zero sequence connected through a measuring transformer. 2. The method according to claim 1, characterized in that the emergency conditions are calculated taking into account the influence of: asymmetries of the own and mutual resistances of the phases of the line, phase-excellent load, transformer parameters, transient resistances, power and tangent of the load angle, static load characteristics.
