Abstract
Изобретение относитс к энергетике и позвол ет повысить надежность способа. Дл этого закрытие направл ющего аппарата и разъединение валов генератора и турбины начинают одновременно, измер ют разницу скоростей вращени этих валов, а перевод генератора в режим синхронного компенсатора производ т при наличии разницы скоростей вращени между валами 1 ил.The invention relates to power engineering and makes it possible to increase the reliability of the method. For this purpose, the closing of the guide vane and the separation of the generator and turbine shafts begin simultaneously, the difference in the rotational speeds of these shafts is measured, and the generator is switched to the synchronous compensator mode when there is a difference in the rotational speeds between shafts 1 or less.
Description
Изобретение относитс к гидроэнергетике , в частности к способам управлени гидроагрегатами.The invention relates to hydropower, in particular, to methods for controlling hydraulic units.
Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.
На чертеже представлена схема системы управлени дл реализации способа перевода гидроагрегата в режим синхронного компенсатора.The drawing shows a control system diagram for implementing a method for switching a hydraulic unit to a synchronous compensator mode.
Система управлени содержит электрически св занные с реле 1 включени останова механизм 2 закрыти направл ющего аппарата 3 турбины 4, механизм 5 разъединени валов 6 и 7 соответственно турбины 4 и генератора 8, реле 9 перевода генератора 8 в режим синхронного компенсатора и другие аварийные датчики (на чертеже не показаны). К реле 9 подключен датчик 10 разности скоростей вращени валов 6 и 7. В вале 7 размещены подвижные пальцы 11 дл соединени валов 6 и 7.The control system contains electrically connected with the stop-on relay 1, the mechanism 2 for closing the guide vanes 3 of the turbine 4, the mechanism 5 for disconnecting the shafts 6 and 7 of the turbine 4 and the generator 8, the relay 9 for switching the generator 8 into a synchronous compensator, and other alarm sensors (on drawing not shown). A sensor 10 of the difference in the speeds of rotation of the shafts 6 and 7 is connected to the relay 9. In the shaft 7 there are movable fingers 11 for connecting the shafts 6 and 7.
Способ реализуетс следующим образом.The method is implemented as follows.
В случае необходимости останова гидроагрегата из-за недопустимого отклонени режима работы или повреждени в узлах гидротурбины закрывают направл ющий аппарат 3 и разъедин ют валы 7 и 6 генератора 8 и турбины 4, причем закрытие направл ющего аппарата 3 и разъединение валов 7 и 6 начинают одновременно, дл чего включают реле 1, которое включает в работу механизм 2 закрыти направл ющего аппарата 3 и механизм 5 разъединени , последний выводит пальцы 11 из зацеплени с валом 6. После разъединени валов 6 и 7 производ т перевод генератора 8 в режим синхронного компенсатора при наличии разницы скоростей вращени между валами 6 и 7, которую фиксируют датчиком 10, он включает реле 9 перевода генератора 8 в режим синхронного компенсатора и останавливают ротор турбины 4.If it is necessary to stop the hydraulic unit due to an unacceptable deviation of the mode of operation or damage to the hydraulic turbine units, the guiding device 3 is closed and the shafts 7 and 6 of the generator 8 and the turbines 4 are disconnected, and the closing of the guiding device 3 and the separation of the shafts 7 and 6 start simultaneously For this purpose, the relay 1 is turned on, which activates the mechanism 2 for closing the guide device 3 and the mechanism 5 for disengagement, the latter disengages the fingers 11 from the engagement with the shaft 6. After disconnecting the shafts 6 and 7, the generator 8 is brought into mode Synchro compensator in the presence of rotational speed difference between the shafts 7 and 6 which are fixed sensor 10, it switches the relay 9 of the generator 8 and the translation in the synchronous compensator mode and the turbine rotor 4 is stopped.
