Description
(54) СПОСОБ ПРЕКРАЩЕНИЯ АСИНХРОННОГО ХОДА В ЭЛЕКТРОПЕРЕДАЧЕ(54) METHOD OF TERMINATION OF ASYNCHRONOUS PROCESS IN ELECTRICAL TRANSMISSION
Изобретение относитс к электротехнике , в частности, к способам прекращени асинхронных режимов в сет х высокого и сверхвысокого напр жений ..This invention relates to electrical engineering, in particular, to methods for terminating asynchronous modes in high and ultra high voltage networks.
Известны способы прекращени асинхронного хода в электропередаче,при которых с целью предотвращени разрыва больших уравнительных токов и снижени величин перенапр жений, разрывают передачу вблизи момента совпадени фаз напр жений по концам электропередачи rj и 2 .Methods are known for stopping an asynchronous run in power transmission, in which, in order to prevent the breaking of large equalizing currents and reduce overvoltages, the transmission is interrupted near the moment of coincidence of the phases of the voltages at the ends of the power transmission rj and 2.
Недостатком данных способов вл етс зат гивание асинхронного режима, что приводит к увеличению длительности снижени напр жений в энергосистеме и возможности дополнительных ава- . рийных отключений потребителей и развитий аварии.The disadvantage of these methods is the tightening of the asynchronous mode, which leads to an increase in the duration of the voltage reduction in the power system and the possibility of additional auto- mation. emergency shutdowns of consumers and the development of the accident.
Наиболее близким к предлагаемому изобретению вл етс способ прекращени асинхронного хода в электропередаче сверхвысокого напр жени путем вы влени асинхронного хода на линии и последующего отключени линии с одного конца Р .The closest to the proposed invention is a method of stopping an asynchronous run in an ultrahigh voltage power transmission by detecting an asynchronous run on a line and then disconnecting the line from one end of P.
Согласо известному способу производ т одностороннее отключение линии, причем отключение задают на.том концеAccording to a known method, one-way disconnection of the line is performed, and the disconnection is set at that end.
линии, где перенапр жени при этом меньше. Однако при больших углах между векторами ЭДС они могут не менее значительно превышать допустимый уровень. Дл электропередач. , содержащих два последовательных .. участка линии и промежуточную подстанцию с двум или более трансформаторами , такой способ прекращ ени lines where overvoltages are less. However, at large angles between the EMF vectors, they can no less significantly exceed the permissible level. For power transmission. containing two consecutive line sections and an intermediate substation with two or more transformers, this method of termination
