Inkqubo yoLawulo lokuSebenza okuFanayo

Ingcaciso yeMveliso

Okokuqala, zeziphi iimeko zokusebenza ngaxeshanye kweeseti zejenereyitha?
Yonke inkqubo yokufaka iseti yejenereyitha ekusebenzeni ngaxeshanye ibizwa ngokuba yi-parallel operation. Iseti yokuqala yejenereyitha iya kusebenza, i-voltage ithunyelwa kwibhasi, kwaye enye iseti yejenereyitha emva kokuqala, kunye neseti yangaphambili yejenereyitha, kufuneka ibe kufutshane nomzuzu wokuvala, iseti yejenereyitha akufuneki ibonakale iyingozi, i-shaft ayichaphazeleki ngequbuliso. Emva kokuvala, i-rotor kufuneka itsalwe ngokukhawuleza kwi-sync. (oko kukuthi, isantya se-rotor silingana nesantya esilinganisiweyo). Ke ngoko, iseti yejenereyitha kufuneka ihlangabezane nale miqathango ilandelayo:
1. Ixabiso elisebenzayo kunye nemo ye-waveform ye-voltage yeseti yejenereyitha kufuneka ifane.
2. Isigaba sombane seejenereyitha ezimbini siyafana.
3. Ubuninzi beeseti ezimbini zejenereyitha buyafana.
4. Ulandelelwano lwesigaba seeseti ezimbini zejenereyitha luyahambelana.

Okwesibini, yeyiphi indlela ye-quasi-synchronous juxtaposition yeeseti zejeneretha? Ungayenza njani i-juxtapositions ngaxeshanye?
Ixesha elichanekileyo lilingana neli. Ngendlela ye-quasi-synchronous yokusebenza okulinganayo, i-voltage yeseti yejenereyitha kufuneka ifane, i-frequency iyafana kwaye isigaba siyafana, esinokujongwa zii-voltmeter ezimbini, iimitha ezimbini ze-frequency kunye nezibonisi ze-synchronous kunye ne-non-synchronous ezifakwe kwi-synchronous disk, kwaye amanyathelo okusebenza okulinganayo ngala alandelayo:
Iswitshi yomthwalo yeseti enye yejenereyitha ivaliwe, kwaye i-voltage ithunyelwa kwibha yebhasi, ngelixa enye iyunithi ikwimeko yokulinda.
Vala ukuqala kwexesha elifanayo, lungisa isantya seseti yejenereyitha yokulinda, ukuze ilingane okanye isondele kwisantya esihambelanayo (umahluko wefrikhwensi nenye iyunithi ngaphakathi kwesiqingatha somjikelo), lungisa i-voltage yeseti yejenereyitha yokulinda, ukuze isondele kwi-voltage yeseti yejenereyitha yomnye, xa i-frequency kunye ne-voltage zifana, isantya sokujikeleza setafile ehambelanayo sicotha kwaye sicotha, kwaye ukukhanya kwesalathisi nako kukhanye kwaye kumnyama ngaxeshanye; Xa isigaba seyunithi eza kudityaniswa sifana neseyunithi enye, i-synchronous meter pointer ibonisa indawo ephakathi yesikwere esingaphezulu, kwaye isibane esihambelanayo sincinci. Xa umahluko wesigaba phakathi kweyunithi eza kudityaniswa kunye nenye iyunithi mkhulu, i-synchronous meter ikhomba kwindawo esembindini engezantsi, kwaye isibane esihambelanayo sivuliwe ngeli xesha. Xa i-synchronous meter pointer ijikeleza ngokwewotshi, ibonisa ukuba i-frequency yejenereyitha yokuhambelana iphezulu kuneyenye iyunithi. Isantya seseti yejenereyitha yokulinda kufuneka sincitshiswe, kwaye isantya seseti yejenereyitha yokulinda kufuneka sonyuswe xa i-pointer yewotshi ijikeleziswa ngokuchasene newotshi. Xa isalathisi sewotshi sijikeleza kancinci kwicala lewotshi kwaye isalathisi sisondela kwindawo enye, i-circuit breaker yeyunithi eza kudityaniswa iyavalwa ngoko nangoko, ukuze iiseti ezimbini zejenereyitha zihambelane. Iiswitshi zechronograph ezikhutshwe ecaleni kunye nee-chronoswitshi ezinxulumene nazo.

Okwesithathu, yintoni ekufuneka iqwalaselwe xa kusenziwa i-quasi-synchronous juxtaposition yeseti yejenereyitha?
I-Quasi-synchronous parallel yindlela yokusebenza ngesandla, nokuba umsebenzi uhamba kakuhle kwaye amava omqhubi anobudlelwane obuhle, ukuze kuthintelwe i-synchronous parallel eyahlukeneyo, la matyala mathathu alandelayo awavumelekanga ukuvala.
1. Xa isalathisi setafile ehambelanayo sibonakala njengesiganeko sokutsiba, akuvumelekanga ukuba sivaleke, kuba kunokubakho isiganeko sekhasethi ngaphakathi kwetafile ehambelanayo, esingabonisi iimeko ezifanelekileyo zokudibana.
2. Xa itafile ehambelanayo ijikeleza ngokukhawuleza kakhulu, ibonisa ukuba umahluko wefrikhwensi phakathi kweseti yejenereyitha kunye neseti yejenereyitha enye inkulu kakhulu, kuba ixesha lokuvala le-circuit breaker kunzima ukulilawula, i-circuit breaker ayivalwanga ngaxeshanye, ngoko ke ayivumelekanga ukuvala ngeli xesha.
3. Ukuba isalathisi sewotshi siyema ngaxeshanye, asivumelekanga ukuba sivale. Oku kungenxa yokuba ukuba imvamisa yesinye sezi zixhobo zejenereyitha itshintsha ngequbuliso ngexesha lenkqubo yokuvala, kunokwenzeka ukuba i-circuit breaker ivale nje kwindawo engangqamananga.

Okwesine, ungayilungisa njani imeko yamandla angasemva yeeyunithi ezifanayo?
Xa iiseti ezimbini zejenereyitha zingasebenzi, kuya kubakho umahluko wefrikhwensi kunye nomahluko wevolthi phakathi kweeseti ezimbini. Kwaye kwisixhobo sokujonga iiyunithi ezimbini (i-ammeter, imitha yamandla, imitha yefactor yamandla), imeko yamandla e-inverse iyabonakala, enye ngamandla a-inverse abangelwa sisantya esingaguqukiyo (i-frequency), enye ngamandla a-inverse abangelwa yivolthi engalinganiyo, ehlengahlengiswa ngolu hlobo lulandelayo:
