(54) СПОСОБ ОДНОФАЗНОГО АВТОМАТИЧЕСКОГО ПОВТОРНОГО ВКЛЮЧЕНИЯ ЛИНИИ ЭЛЕКТЮПЕРЕДАЧИ(54) METHOD FOR SINGLE-PHASE AUTOMATIC REPEATED INCLUSION OF ELECTRICAL TRANSMISSION LINES
II
Изобретение относитс к электротехнике, .конкретно к электрическим сет м сверхвысокого напр жени .The invention relates to electrical engineering, specifically to electric networks of ultra-high voltage.
Известен способ однофазного автоматического повторного включени линии электропередачи сверхвысокого напр жени с шунтирующими реакторами, заключающийс в том, что после отключени поврежденной линии измер ют напр жени и их приращени и по результатам анализа этих измерений определ ют момент погасани дуги и исключают повторное включение на неустановившеес повреждение 1.A known method of single-phase automatic re-activation of an ultrahigh voltage power line with shunt reactors, which means that after disconnecting the damaged line, the voltages and their increments are measured and the moment of extinction of the arc is determined by analyzing these measurements and the repeated activation of the unstable damage is excluded 1 .
Недостатками данного способа вл ютс сложность выполнени узла, реагирующего на приращени напр жени , и больща погрешность из-за неодинаковости изменени напр жени на носледуюидих интервалах измерени , а также случайность определени границ интервалов измерени .The disadvantages of this method are the difficulty of performing a node that reacts to voltage increments, and a larger error due to the unevenness of the voltage change at the next measuring intervals, as well as the randomness of determining the boundaries of the measurement intervals.
Наиболее близким к предлагаемому вл етс способ однофазного автоматического включени линии электропередачи, к которой подключены трансформаторы, имеющие обмотки, соединенные в треугольник, заключающийс вClosest to the present invention, there is a method of single-phase automatic switching on of a power line, to which transformers are connected, having windings connected in delta, consisting of
ТОМ, что отключают поврежденную фазу линии контролируют напр жение на ней и повторно включают отключенную фазу 2.A VOLUME that disconnects the damaged phase of the line controls the voltage across it and re-enables the disconnected phase 2.
Недостатками данного способа вл ютс отсутствие фиксации погасани дуги подпитки и невозможность максимального снижени бестоковой паузы.The disadvantages of this method are the lack of fixation of the extinction of the arc of feed and the impossibility of maximally reducing the dead time.
Цель изобретени - сокращение бестоковой паузы однофазного автоматического повторного выключени путем фиксации момента погасани The purpose of the invention is to reduce the current-free pause of a single-phase automatic restart by fixing the moment of extinction.
10 дуги подпитки.10 arc feed.
Поставленна цель достигаетс тем, что согласно способу однофазного автоматического повторного включени линии электропередачи, The goal is achieved by the fact that, according to the method of single-phase automatic re-inclusion of the transmission line,
15 к которой подключены трансформаторы, имеющие обмотки, соединенные в треугольник, заключающемус в том, что отключают поврежденную фазу линии, контролируют вектор напр жени на ней и повторно включают отключенную фазу, 15 to which are connected transformers with windings connected in delta, consisting in the fact that they disconnect the damaged phase of the line, control the voltage vector on it and re-enable the disconnected phase,
