Uzikhuselwa njani iiLophu kuSetyenziso oluFanayo lweJenereyitha

Ukusebenza ngokunxuseneyo kuthetha ukuba iiseti zejeneretha ezimbini okanye ngaphezulu ezinevoltheji elinganayo kunye nesigaba esingaguqukiyo zidityaniswe kwibhasi enye ukunika amandla asebenzayo kunye nomthamo osebenzayo kwisixhobo.Isethi enye yejeneretha iqalwa kuqala, kwaye ke amandla ombane avelisiweyo athunyelwa ebhasini.Emva kokuba enye iseti yejenereyitha iqalisiwe, ihambelana neseti yangaphambili yejenereyitha ngalo mzuzu.Ngomzuzu wokuvala, iseti yejenereyitha ayisayi kuba nempembelelo yangoku engaqhelekanga, kwaye i-crankshaft ayizuchaphazeleka ngesiquphe.Nangona kunjalo, isiphaluka ngokubanzi sangoku kufuneka siqwalaselwe ngokubanzi kumanyathelo okusebenza okusebenza okufanayo.

1. Ukubuyisela umva umsebenzi.Imeko yangoku yamandla okubuyisela umva ibangelwa yisantya esahlukileyo kunye nombane we iiyunithi zejeneretha , oko kukuthi, enye iyunithi ye-generator inamandla afanelekileyo kwaye enye iyunithi inamandla angalunganga.Ngamanye amazwi, iyunithi enomthamo ongalunganga iba ngumthwalo ngeli xesha (imeko yangoku ye-frequency ephantsi kunye nesantya esingahambelaniyo sale yunithi).Xa i-voltage ingahambelani, iyunithi ene-voltage ephezulu inika i-voltage enye esebenzayo kunye ne-reactive voltage kwiyunithi ene-low voltage (uphawu oluhle lwe-ammeter yale yunithi).Ilingana nokongeza iqela le-condenser kwinkqubo yonikezelo lwamandla.Ngeli xesha, iyunithi ene-voltage ephantsi iba ngumthwalo omkhulu kwaye ifumana i-current reactive current enkulu ukuze kuqinisekiswe ibhalansi yombane yeeyunithi ezimbini (i-ammeter yale yunithi ibonisa umva).Ngexesha lokubeka iliso, xa i-voltage yeyunithi enye inyuswa okanye i-voltage yenye iyunithi inyusiwe, enye iyunithi inamandla ombane ajikelezayo, kunye nokuziphatha kwayo ngoku malunga ne-20% ye-current rated current.Reverse acting relay izenzo, iihambo kunye nezivusi, kodwa ayivalwa.

2. Ixesha elidluleyo.Umthamo wemveliso yesethi yejeneretha yanamhlanje iyahambelana, kwaye inqanaba layo lokulayisha liphantsi kakhulu.Uninzi lwazo lujikeleze i-5% yomthamo wemveliso.Ixesha elivumelekileyo lomthwalo li-15 ~ 30 imizuzu, ukuya kwimizuzu engama-60.Ngaphezu koko, ngelo xesha Iseti yejeneretha yePerkins iya kutshisa, i-insulation yekhebula iya kuncitshiswa, kwaye ubomi benkonzo buya kuncitshiswa.Ngoko ke, ukuba akukho mfuneko ekhethekileyo xa ubeka ukukhuselwa kwe-overcurrent, ukukhuselwa kwe-overcurrent kunokusetwa kwi-110% ye-current rated current.Ngethuba lovavanyo lomthwalo, zisa i-current kwi-110% ye-current rated current, kunye ne-overcurrent relay acts.Uhambo, i-alam kunye nokungacinywa.

3. Ukugqithiswa kwamandla.Xa isethi ye-generator isetyenziswe ngokufanayo, iyoyika kakhulu i-oscillation yenkqubo yokubonelela ngombane.Emva kokuba i-oscillation isenzeka, ukunyuka kwe-voltage yenkqubo kulula ukuvelisa ukuchithwa kwe-insulation yezixhobo zombane kunye nenkqubo yokubonelela ngombane, eyenza inkqubo yokubonelela umbane kunye nezixhobo zombane zingakwazi ukusebenza ngokuqhelekileyo.Ke ngoko, iiseti zejeneretha ezisetyenziswe ngokuhambelanayo zixhotyiswe ngokukhuselwa kwe-overvoltage, kwaye ixabiso layo lokuseta kwangaphambili le-105% yombane olinganisiweyo ungcono.Isiphaluka esifutshane se-overvoltage relay, uhambo, ukuvala kunye ne-alamu.Ingabonwa ukuba isantya (i-frequency) ukulungiswa kweeyunithi ezimbini kufuneka zihambelane ngaphambi kokulungiselela ukusebenza okufanayo kweeyunithi ze-generator.Ngokunxuseneyo, isantya somatshini wokuqala okanye iqela eliza kuhanjiswa lilungelelaniswe ngokwesantya sokujikeleza kwetafile ngexesha elinye, ukwenzela ukuba ulwalathiso olujikelezayo lwetheyibhile ngexesha elinye lunokujikelezwa ngokwewotshi okanye ngokunxamnye newotshi. .Isantya esicothayo, kokukhona singcono, kodwa isalathisi setafile ngexesha elinye kufuneka sijikelezwe phambi kokuba sibe kwicala elinye.Ekugqibeleni, emva kwecala-ngecala, khangela ukuba i-current and capacity of the two units are balanced.Ukuba umahluko mkhulu kakhulu, lungisa iqhosha lesantya ukugcina amandla.
