Ndeapi Mhedzisiro Yekunakidzwa Kurasikirwa kune Jenareta

Munguva yekushanda kwakajairika kwejenareta, kunakidzwa kunongoerekana kwanyangarika zvachose kana zvishoma, izvo zvinonzi kurasikirwa kwekunakidzwa kwejenereta.

Pakati pezvikamu zve diesel generator set, jenareta inokosha zvikuru.Mushure menguva refu yekushandiswa kwedhiziri generator set, jenareta inogona kurasikirwa nekunakidzwa.Mamiriro ezvinhu aya akajairika.Asi mamiriro ezvinhu aya achakanganisa hurongwa. Ndedzipi mhedzisiro yekunakidzwa kwekurasikirwa kune jenareta?

1.Low-excitation uye kurasikirwa-kwe-excitation jenereta inotora simba rinogadzirisa kubva muhurongwa, zvichiita kuti mhepo yemagetsi idonhe.Kana iyo reactive simba rekuchengetedza musimba remagetsi isina kukwana, voltage yemamwe mapoinzi musimba remagetsi ichave yakaderera pane Iyo inotenderwa kukosha inoparadza yakagadzikana mashandiro pakati pemutoro uye yega yega sosi yemagetsi, uye inotokonzera kuti voltage yemagetsi system kuparara.

2. Kana jenareta inorasikirwa nekunakidzwa kwayo, nekuda kwekudonha kwemagetsi, mamwe majenereta ari musimba remagetsi anozowedzera simba rawo rekuita pasi pechiito chekugadzirisa otomatiki kwechigadzirwa chekusimudzira, nekudaro zvichikonzera zvimwe. jenareta , transformers kana mitsara kune overcurrent , Kudzivirirwa kwayo kwekuchengetedza kunogona kusashanda nekuda kwekudarika, izvo zvichawedzera chiyero chetsaona.

3.Mushure mekunge jenareta yarasa magnetization, nekuda kwekuzunguzika kwesimba rinoshanda rejenareta uye kudonha kweiyo system voltage, zvinogona kuita kuti iri padyo neakajairika majenereta ekushandisa nehurongwa, kana pakati pezvikamu zvakasiyana zvesimba remagetsi, kurasikirwa. synchronization, zvichiita kuti sisitimu irasikirwe newirirano.Oscillation inoitika.

4.Iyo yakakura yehuwandu hwehuwandu hwejenereta, iyo yakakura simba rekugadzirisa simba rinokonzerwa nekuderera kwakadzika uye kurasikirwa kwekunakidza, uye kuduku kwesimba remagetsi emagetsi, kuduku kukwanisa kubhadhara iyi simba rekuita.Naizvozvo, kukura kwereshiyo yesimba rejenareta kune huwandu hwese kwesimba remagetsi, zvinotonyanya kuipa kukanganisa kwesimba remagetsi.

Ndechipi chikonzero chekurasikirwa kwekunakidzwa kwejenereta?

(1) Chiratidzo mushure mokunge jenareta yarasikirwa nekunakidza kwayo: stator ikozvino uye simba rinoshanda rejenareta rinokwira nokukurumidza mushure mekudonha pakarepo, uye chiyero chinowedzera uye chinotanga kuzununguka.

(2) Iyo jenareta inogona kuramba ichitumira imwe huwandu hwesimba rinoshanda mushure mekurasikirwa kwekunakidzwa, uye chengetedza kutungamira kwesimba rinoshanda rakatumirwa kunze, asi chinongedzo chemita yemagetsi chinotenderera nguva nenguva.

(3) Sezvo iyo stator ikozvino inowedzera, iyo ammeter pointer zvakare inotenderera nguva nenguva.

(4) Kubva pane yakatumirwa reactive simba kune iyo yakanyudzwa reactive simba, iyo pointer zvakare inotenderera nguva nenguva.Kuwanda kwesimba rinoita rakatorwa rinenge rakaenzana nehuwandu hwesimba rekuita risati rarasikirwa nekunakidzwa.

(5) Rotor redunhu rinoita kushandura ikozvino uye kuchinjanisa magnetomotive simba nekutsvedza frequency, saka pointer ye rotor voltmeter zvakare inotenderera nguva nenguva.

(6) Iyo pointer ye rotor ammeter zvakare inotenderera nguva nenguva, uye kukosha kwazvino kudiki pane iyo isati yarasikirwa nekunakidzwa.

(7) Kana iyo rotor yedunhu yakavhurika, imwe eddy ikozvino inonyengerwa pamusoro peiyo rotor muviri kuti iite inotenderera yemagineti, iyo inoburitsawo imwe huwandu hwesimba reasynchronous.

Nzira yekugadzirisa sei dambudziko rekunakidza kurasikirwa kwejenereta?

(1) Mushure mekurasikirwa kwekunakidzwa kwekudzivirira kwaitwa, iyo yekukurudzira modhi inoshandurwa otomatiki, uye iyo inoshanda yekudzikisa mutoro haina kukodzera uye inoshanda parwendo, ichabatwa sekuvharwa kwetsaona;

(2) Kana iyo de-excitation switch yakagumburwa nekukanganisa, de-excitation switch inofanira kuvharwa zvakare pakarepo.Kana iyo reclose isingabudiriri, jenereta ichabviswa uye inomira pakarepo;

(3) Kana kurasikirwa kwekunakidzwa kuri nekuda kwekutadza kweiyo excitation regulator AVR, nekukurumidza chinja iyo AVR kubva pachiteshi chekushanda kuenda kune yakamira chiteshi, uye chinja kune manyore kushanda kana otomatiki modhi ikatadza;

(4) Mushure mekunge jenareta yarasikirwa nekunakidzwa uye jenareta isingafambi, mutoro unoshanda unofanirwa kuderedzwa kusvika 120MW mukati me1.5min, uye inobvumirwa nguva yekumhanya mushure mekurasikirwa kwemagineti ndeye 15min;

(5) Kana kurasikirwa kwekunakidza kunokonzera kuti jenereta iite, jenereta inofanira kubviswa uye ivhare pakarepo, uye yozobatanidzwazve kune grid mushure mokunge kunakidza kwadzorerwa.

Kana jenareta ikaitika kurasikirwa kwekunakidzwa, isu tinofanira kutsvaga chikonzero uye kugadzirisa dambudziko nenguva, kudzivirira kukanganisa kune jenareta.Dingbo Power haingope rubatsiro rwehunyanzvi, asiwo gadzira dhiziri generator seti , kana uine hurongwa hwekutenga, gamuchirwa kuti utaure nesu neemail dingbo@dieselgeneratortech.com.
