Mgwirizano wa Majenereta

Kukonza mphamvu zosinthira kumatchedwanso kukonza malangizo amphamvu.Nthawi zambiri, mphamvu malangizo a jenereta ayenera kukhala chitsogozo cha jenereta kwa basi, koma pamene jenereta wataya maginito kapena chifukwa china jenereta, jenereta akhoza kusanduka ntchito galimoto, ndiko kuti, jambulani mphamvu yogwira ku dongosolo.Izi ndi mphamvu zopinga.Mphamvu yopingasa ikafika pamtengo wina, kukonzanso kwa jenereta, kapena kuchitapo kanthu kuwonetsa kapena kuchitapo kanthu kuti ifike.

Turbogenerator yolumikizidwa ndi gridi imagwira ntchito ngati injini yolumikizana pambuyo valavu yayikulu ya turbine yatsekedwa: imatenga mphamvu yogwira ndikukokera kugudubuza kwa turbine, komwe kumatha kutumiza mphamvu yogwira ntchito ku dongosolo.Chifukwa valavu yaikulu ya turbine ya nthunzi yatsekedwa, tsamba la mchira wa turbine ya nthunzi imasemphana ndi nthunzi yotsalira ndipo imapanga kuwonongeka kwa kuphulika, komwe kumawonongeka chifukwa cha kutentha kwa nthawi yaitali.Ma turbines a gasi ndi madzi nawonso ali pachiwopsezo chachikulu kwa omwe amasuntha kwambiri.Jenereta yosinthira mphamvu yokonza makina opangira magetsi kuti asawonongeke.

Kuyika mawerengedwe a turbine yosinthira mphamvu yosinthira mphamvu ndikuzindikira mphamvu ya Pdz ndikuchedwa kuchitapo kanthu T pakukonza.

1. Mphamvu yochitapo kanthu ya Pdz set turbogenerator inverse yokonza mphamvu yokonza mphamvu imatha kuwerengedwa motsatira njira iyi: Pdz=(Krel*P1)/η Pdz- Inverse power yokonza mphamvu ya Krel- reliability coefficient, kutenga 0.8 P1- mphamvu yogwiritsidwa ntchito ndi turbine kusunga synchronous kasinthasintha liwiro valavu chachikulu chatsekedwa, kukula kwa mphamvu imeneyi ndi zogwirizana ndi turbine dongosolo ndi mphamvu, Komanso yokhudzana ndi kapangidwe waukulu nthunzi dongosolo turbogenerator (mapangidwe payipi ndi ngati pali kulambalala payipi, etc.), nthawi zambiri amatenga 1.5~2% ya mphamvu zovoteledwa η- mphamvu pamene jenereta kukoka turbogenerator kuzungulira, kutenga 0.98~0.99 kotero: Pdz≈ (1.2~1.6%) PN PN- oveteredwa mphamvu ya jenereta.Pochita, Pdz = ikhoza kukhala 1-1.5% PN.

2. zochita kuchedwa jenereta mosintha mphamvu kukonza zochita kuchedwa, ayenera molingana ndi nthunzi turbine jenereta pambuyo valavu chachikulu chatsekedwa kuloledwa ntchito nthawi kukhazikitsa, nthawi yololedwa zambiri 10 ~ 15min.Mawerengedwe ndi machitidwe ogwirira ntchito akuwonetsa kuti ngati makina opangira magetsi opangira nthunzi ali ndi chitoliro chodutsa, nthawi yovomerezeka yogwira ntchito imakhala yayitali.Choncho, ngati kuchedwa kwa ntchito yokonza kumayikidwa molingana ndi nthawi yomwe imaloledwa kuthamanga pambuyo poti valavu yayikulu ya turbine yatsekedwa, 5 ~ 10min ndiyoyenera.Pambuyo pakuchita, imagwiritsidwa ntchito pochotsa maginito.

Kuphatikiza apo, ma turbogenerators akulu omwe akugwira ntchito nthawi zambiri amagwiritsa ntchito kukonza mphamvu zobwerera kumbuyo kuti ayambitse pulogalamu yaulendo.Pakadali pano, nthawi yochitapo kanthu ndi 1 ~ 2s.Ponena za kusungirako mphamvu zoyendetsedwa ndi pulogalamu, chifukwa cha nthawi yochepa yogwiritsira ntchito, mphamvu yogwiritsira ntchito mphamvu ikhoza kukhala yaying'ono kwambiri pakapita nthawi yochepa kwambiri pambuyo poti nsonga yaikulu ya valve yatsekedwa chifukwa cha inertia ya turbine ndi jenereta. mtengo wosasunthika wa mphamvu yosiyana suyenera kukhala wamkulu kuposa 1% PN.

Pamene jenereta ali n'zosiyana mphamvu (mfundo kunja mphamvu kwa jenereta, ndiye jenereta amakhala chikhalidwe galimoto), n'zosiyana mphamvu yokonza ntchito dera wosweka.Magetsi a magawo atatu ndi ma sign apano a magawo awiri ayenera kusonkhanitsidwa.Chifukwa cha mitundu yosiyanasiyana ya mphamvu zoyambira, ma jenereta osiyanasiyana amatha kupangidwa.Ndi mgwirizano wa madzi ndi makina opangira madzi, hydro-generator ikhoza kupangidwa.Chifukwa cha kusiyana kwa mphamvu yosungiramo madzi ndi kutsika kwa mutu, ma hydrogenerators omwe ali ndi mphamvu zosiyana ndi liwiro amatha kupangidwa.Pogwiritsa ntchito malasha, mafuta ndi zinthu zina, komanso ndi boiler, turbine ndi injini ya nthunzi, jenereta ya turbine imatha kupangidwa, yomwe imakhala yothamanga kwambiri (3000rpm).Kuphatikiza apo, pali mitundu yonse ya ma jenereta omwe amagwiritsa ntchito dzuwa, mphepo, atomiki, geothermal, tidal, bioenergy ndi mphamvu zina.Komanso, chifukwa mfundo ntchito jenereta ndi osiyana, akhoza kugawidwa mu DC jenereta, asynchronous jenereta ndi synchronous jenereta.Ma jenereta akuluakulu omwe amagwiritsidwa ntchito kwambiri ndi majenereta osakanikirana.

Dingbo ili ndi mitundu ingapo ya majenereta a dizilo: Volvo / Weichai / Shangcai/Ricardo/Perkins ndi zina zotero, ngati mukufuna pls tithandizeni
