Chii Chinokonzera Jenareta Pasi Voltage

Jenareta mudziyo wemagetsi unoshandura mamwe marudzi esimba kuita simba remagetsi.Inofambiswa ne turbine yemvura, turbine yemhepo, injini yedhiziri kana mamwe mashini emagetsi, uye inoshandura simba rinogadzirwa nekuyerera kwemvura, kuyerera kwemhepo, kupisa kwemafuta kana nyukireya fission kuita simba remagetsi uye kuriendesa kune jenareta.Yakashandurwa kuita magetsi nejenareta.Majenareta anoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri nekurima, kudzivirira kwenyika, sainzi uye tekinoroji uye hupenyu hwezuva nezuva.

Kune akawanda maitiro e jenareta , asi misimboti yavo yekushanda yakavakirwa pamutemo we electromagnetic induction uye mutemo weelectromagnetic force.Naizvozvo, misimboti yekuvaka kwayo ndeye: shandisa yakakodzera magineti uye conductive zvinhu kugadzira magineti maseketi uye maseketi anoitisa electromagnetic induction nemumwe nemumwe kuburitsa magetsi emagetsi uye kuzadzisa chinangwa chekushandura simba.

Chii chinokonzera jenareta pasi pemagetsi?

(1) Kumhanya kweprime mover kwakadzikira.

(2) Kupokana kweiyo excitation circuit yakakura kwazvo

(3) Iyo exciter bhurashi haisi panzvimbo isina kwayakarerekera, kana kudzvanywa kwechirimo kudiki.

(4) Mamwe madhiodhi ekugadzirisa akaputsika.

(5) Pane pfupi dunhu kana pasi kukanganisa mune stator mhepo kana excitation mhepo.

(6) Iyo yekubata kumeso kwebhurashi idiki kwazvo, kudzvanywa hakuna kukwana, uye kubata kwakashata.Kana iyo yakakonzerwa nepamusoro peiyo commutator, unogona kupuruzira pamusoro peiyo commutator nemucheka we emery pakaderera kumhanya, kana kugadzirisa kudzvanywa kwechirimo.

Nezvikonzero zviri pamusoro, sei kuwedzera jenareta voltage?

1. Gadzirisa kumhanya kweprime mover kune yakayerwa kukosha.

2. Deredza kupikisa kwemagnetic field rheostat kuti uwedzere kufadza ikozvino.Kune semiconductor excitation jenareta, tarisa kuti mamwe majoini anomonereka akadimburwa here kana kuti akabatana zvisizvo.

3. Gadzirisa bhurashi panzvimbo yakarurama, shandura bhurashi, gadzirisa kudzvinyirira kwechitubu.

4. Tarisa uye shandura diode yekuputsika.

5. Tarisa kukanganisa uye kuibvisa.

Dzimwe nzira dzekuwedzera jenareta voltage:

Wedzera uremu hwekusimudzira wejenereta;

kuwedzera kukurumidza kwejenereta;

Deredza kushorwa kwedunhu mujenereta;

Kureruka kwemutoro kana kuwanda kwekunakidzwa kunowedzera sezvo mutoro unowedzera.

Maitiro ekuchengeta jenareta terminal voltage isina kuchinjika

Kana mutoro wezvino wejenareta uchinje, zvichienderana nekunze kwechimiro curve, iyo terminal voltage yejenareta ichachinja nayo.

Kuti uchengetedze magetsi emagetsi ejenareta nguva dzose, iyo yekukurudzira ikozvino yejenereta inofanira kugadziriswa maererano.

Pasi pemamiriro ekuchengetedza kukurumidza, simba rekutakura chinhu uye terminal voltage isina kuchinjwa, hukama huri pakati peiyo excitation IL uye mutoro ls inonzi hunhu hwekugadzirisa jenareta.

Kune mitoro inodzivirira uye inductive, sezvo mutoro unowedzera, iyo terminal voltage yejenareta inoderera zvishoma nezvishoma.Kuti uchengetedze iyo terminal voltage isina kuchinjika, iyo yekuwedzeredza ikozvino inofanirwa kuwedzerwa zvinoenderana kutsiva iyo demagnetization uye leakage reactance yearature reaction.pressure drop.

Kune capacitive mitoro, sezvo iyo terminal voltage yejenareta ichiwedzera nekuwedzera kwemutoro wazvino, iyo yekuwedzeredza ikozvino inofanirwa kudzikiswa kuti ibvise iyo excitation mhedzisiro yearature reaction uye kuwedzera mhedzisiro yekudonha kwekuita, kuitira kuchengetedza terminal voltage.nguva dzose.

Matambudziko anofanirwa kucherechedzwa kana uchienderana neasina-mutoro jenareta negiredhi remagetsi: panguva yekuchinja nekuvhara, jenareta haifanirwe kuve neinokuvadza inrush ikozvino, uye shaft inotenderera haifanirwe kungoerekana yavhunduka.

Mushure mekuvhara, iyo rotor inofanira kukwanisa kudhonzwa mukuenderana nekukurumidza (kureva kuti, iyo rotor kumhanya yakaenzana neyakayerwa kumhanya).Nechikonzero ichi, iyo synchronous jenareta inofanirwa kusangana nemamiriro anotevera:

1. Kukosha kunoshanda kwe jenareta voltage inofanira kuenzana nehuwandu hunobudirira hwegridhi voltage.

2. Chikamu chemagetsi ejenareta uye chikamu chemagetsi emagetsi chinofanira kunge chakafanana.

3. Kuwanda kwejenereta kwakaenzana nehuwandu hwegridhi.

4. Kutevedzana kwechikamu chemagetsi ejenareta kunopindirana nechikamu chechikamu chemagetsi emagetsi.

5. Inorambidzwa zvachose kutumira magetsi kumashure emagetsi.
