Aikin da Turbin Induction

Takaitaccen Induction Generator

Induction generator (ko kuma yana canzawa ne asynchronous generator) yana nufin induction machine da ake amfani da shi wajen gina karamin bincike.

Sauran Yadda Ake Amfani Da Shu

Induction generators sun yi aiki idan slip na bi da dace, wanda ake samun ta bayan ya sa shi da sama da prime mover speed zuwa hukumar synchronous speed.

Muhimmancin Maimaitar Current Da Mai Kirkiro

Sun bukata maimaitar current da mai kirkiro daga cikin batutuwar, ko kuma da generators masu muhimmiyar.

Self-Excited Generators

Wannan irin, ko kuma yana canzawa ne self excited generator, yana amfani da capacitor bank da aka saka a kan stator terminals don bayar da zaruri da ke mai kirkiro.

Ayyukan capacitor bank shine bayar da mai kirkiro ga induction generator da kuma load. Saboda haka za a iya rubuta total reactive power da capacitor bank ya bayar da shi daidai da summation of the reactive power consumed by the induction generator da kuma load.

Yana faru small terminal voltage oa (kamar da ake bayyana a cikin figure) a kan stator terminal saboda residual magnetism idan rotor na induction machine ya tafi da sama da abubuwan da ke bukata. Saboda wannan voltage oa an fara capacitor current ob. An yi current bc wanda ya fara current od wanda ya fara voltage de.

 Cumulative process of voltage generation ya ci gaba har zuwa lokacin da saturation curve na induction generator ya kasa capacitor load line a wani wurin. Wannan wurin ya danganta f a cikin given curve.

Amfani Da Induction Generator

Za a iya hadada amfani da induction generator: Akwai duwatsu na induction generator, za a iya hadada amfani da kowace irin generator: Externally excited generators sun fiye da amfani wajen regenerative breaking of hoists driven by the three phase induction motors.

Self-excited generators sun amfani a wind mills. Saboda haka wannan irin generator yana taimakawa wajen kawo unconventional sources of energy zuwa electrical energy.

Yanzu za a iya hadada wasu disadvantages na externally excited generator:

• Efficiency na externally excited generator ba ta da kyau.

• Ba zan iya amfani da externally excited generator a lagging power factor wanda yana cewa major drawback na irin generator.

• Amount of reactive power da ke bukata don run these types of generator yana da goma.

Abubuwan Induction Generators

• Yana da takamarta da ke bukatar lafiya ita ce.

• Relatively cheaper

• Small size per kW output power (i.e. high energy density)

• It runs in parallel without hunting

• No synchronization to the supply line is required like a synchronous generator

Kasashen Induction Generators

Ba zan iya gina reactive voltamperes. It requires reactive voltamperes from the supply line to furnish its excitation.
