Abstract

FIELD: electromechanical engineering; wind- electric power plants. SUBSTANCE: synchronous generator has rotor and stator whose magnetic circuit is built up of magnetically isolated cores carrying ac winding coils. Novelty is that rotor has even number of magnetically isolated cores with electrically isolated field coils; even and odd field coils are connected to DC supply of different polarity; rotor is designed for partial connection of field coils so that only those located within the region of stator ac winding coils connected to load are energized. Generator provides for producing current at industrial frequency of 50 Hz at low rotor speed without reduction unit for transmitting mechanical energy from slow-speed drive motor, such as wind-electric plant, with low power requirement for excitation. EFFECT: enlarged functional capabilities. 2 dwg

Изобретение относится к электромашиностроению, в частности к синхронным генераторам переменного тока и может быть использовано в ветроэнергетических установках. Синхронный генератор содержит ротор и статор, магнитопровод которого выполнен в виде магнитоизолированных сердечников, на которых размещены катушки обмотки переменного тока. Новым в синхронном генераторе является то, что ротор выполнен из четного числа магнитоизолированных сердечников с электрически не связанными катушками обмотки возбуждения, при этом четные и нечетные катушки обмотки возбуждения ротора подключены к источнику постоянного тока разной полярности, а также ротор выполнен с возможностью частичного включения катушек обмотки возбуждения, и подключены только те катушки обмотки возбуждения, которые находятся в зоне расположения сердечников статора с катушками обмотки переменного тока, подключенными к нагрузке. При использовании предлагаемого изобретения можно получить электрический ток промышленной частоты 50 Гц при малых оборотах ротора без редукторной передачи механической энергии от малооборотного двигателя привода, например ветроэнергетической установки, к генератору при минимальном расходе электроэнергии на возбуждение.The invention relates to electrical engineering, in particular to synchronous alternators and can be used in wind power plants. The synchronous generator contains a rotor and a stator, the magnetic circuit of which is made in the form of magnetically insulated cores, on which the AC winding coils are placed. New in the synchronous generator is that the rotor is made of an even number of magnetically insulated cores with electrically unconnected field winding coils, while the even and odd coils of the field winding of the rotor are connected to a direct current source of different polarity, and the rotor is also able to partially turn on the coil coils excitation, and only those excitation coil coils that are located in the area of the stator cores with the AC winding coils are connected, nnym load. Using the present invention, it is possible to obtain an electric current of industrial frequency 50 Hz at low rotor speeds without the gear transmission of mechanical energy from a low-speed drive motor, such as a wind power installation, to a generator with a minimum energy consumption for excitation.
