Description
Изобретение относитс к электроэнергетике , в частности к устройствам дл пуска турбогенераторов.The invention relates to power engineering, in particular, to devices for starting up turbo-generators.
Цель изобретени - сокращение времени пуска турбоагрегата и снижение расхода топлива.The purpose of the invention is to reduce the start-up time of the turbine and reduce fuel consumption.
На чертеже представлена схема устройства.The drawing shows a diagram of the device.
Устройство дл пуска турбоагрегата содержит источник 1 пара, генератор 2, соединенный валом с турбиной 3, резервный возбудитель 4, подключенный к обмотке возбуждени генератора 2, и трансформатор 5 подключенный к обмотке статора генератора. Устройство дополнительно содержит источник 6 напр жени переменной частоты, соединенный с трансформатором 5. Генератор 2The device for starting the turbine unit contains a source of 1 pair, a generator 2 connected to the turbine 3 by a shaft, a backup exciter 4 connected to the excitation winding of the generator 2, and a transformer 5 connected to the stator winding of the generator. The device further comprises a variable frequency voltage source 6 connected to a transformer 5. Generator 2

подключен к сети через трансформатор 7.connected to the network through a transformer 7.
Устройство работает следующим образом.The device works as follows.
5 В начале запускают в работу источник 6 переменной частоты, который через трансформатор 5 электрически св зан с генератором 2. Трансформатор 7 отключен от сети. Изменением частоты источника 6 напр жени повышают обороты роторов генератора 2 и турбины 3. Одновременно в турбину подаетс пар от источника 1 пара. После достижени номинальных оборотов генератор включают в сеть согласно инструкции. При таком способе пуск турбины осуществл етс независимо от источника пара, что сокращает врем пуска и снижает расход топлива.5 At the beginning, a variable frequency source 6 is started up, which is electrically connected to transformer 5 via transformer 5. Transformer 7 is disconnected from the network. By varying the frequency of the voltage source 6, the speed of the rotors of the generator 2 and the turbine 3 is increased. At the same time, steam is supplied to the turbine from the source 1 of the pair. After reaching the rated speed the generator is switched on in accordance with the instructions. With this method, the turbine is started up independently of the steam source, which reduces the start-up time and reduces fuel consumption.
