Uhlelo lokulawula ukusebenza kwe-Parallel
Ukuchazwa Komkhiqizo
Okokuqala, yini imibandela yokusebenza okuhambisanayo kwamasethi we-generator?
Yonke inqubo yokubeka i-generator isethi yokusebenza ngokufana ibizwa ngokuthi ukusebenza ngokufana. Isethi yokuqala ye-generator izoqhutshwa, i-voltage ithunyelwa ebhasini, kanti enye i-generator isethwe ngemuva kokuqala, futhi isethi yokuvala eyedlule, kufanele ibe ngesikhathi sokuvala, i-shaft ayiveli ngokuya ngomthelela ongazelelwe. Ngemuva kokuvalwa, i-rotor kufanele idonswe ngokushesha ekuvumelaniseni. (okungukuthi, ijubane le-rotor lilingana ngejubane elilinganiselwe) Ngakho-ke, isethi ye-generator kumele ihlangabezane nale mibandela elandelayo:
1. Inani elisebenzayo kanye ne-waveform ye-generator set voltage kumele ifane.
2. Isigaba se-voltage sabakhiqizi bobabili siyafana.
3. Imvamisa yamasethi womakhiqizi amabili ayalingana.
4. Ukulandelana kwesigaba kwamasethi womakhiqizi amabili akuguquguquki.
Okwesibili, iyiphi indlela yokuvumelanisa ye-quxtaposition ye-QuASI-sychchronous yamasethi we-generator? Ungayenza kanjani ama-juxtaposition afanayo?
I-Quasi-synchronous yisikhathi esiqondile. Ngendlela yokuvumelanisa ye-quasi yokusebenza okuhambisanayo, i-generator setha voltage kumele ibe efanayo, imvamisa iyafana futhi isigaba siguqulwe, esingabhekwa ngama-volmeter amabili, amamitha amvamisa afakiwe nezinkomba ezivumelanayo ezifakiwe I-disk ye-synchronous, kanye nezinyathelo zokusebenza ezihambisanayo zimi ngalendlela elandelayo:
Ukushintshwa komthwalo kwesethi eyodwa ye-generator kuvaliwe, futhi i-voltage ithunyelwa kubha yebhasi, kanti enye iyunithi isesimweni sokulinda.
Vala ukuqala kwenkathi efanayo, lungisa ijubane lesethi ye-generator yokulinda, ukuze lilingane nejubane lokuvumelanisa (umehluko wemvamisa ngelinye iyunithi ngaphakathi kwengxenye yesethi yomjikelezo), Ukuze kusondele kumandla kagesi womunye ama-generator set, lapho imvamisa namandla ashukumisayo kufana, ijubane lokujikeleza kwetafula elivumelanayo lihamba kancane futhi lihamba kancane, futhi ukukhanya kwenkomba nakho kukhanya futhi kumnyama at ngasikhathi sinye; Lapho isigaba seyunithi sizohlanganiswa siyefana naleso solunye uphiko, i-synchronous meter pointer ikhombisa isikhundla esiphakathi esiphakathi nendawo, nesibani esivumelanayo sifiphele. Lapho umehluko wesigaba phakathi kweyunithi ukuhlanganiswa futhi enye iyunithi inkulu, amaphuzu wemitha avumelanayo endaweni yesikhungo ngezansi, bese isibani esivumelanayo sikhona ngalesi sikhathi. Lapho i-synchronous meter polliinter ijikeleza iwashi, kukhombisa ukuthi imvamisa ye-generator evumelanayo ephakeme kunaleyo yomunye uphiko. Ijubane lesethi ye-generator yokulinda kufanele lincishiswe, futhi ijubane lesethi ye-generator yokulinda kufanele likhuphuke lapho i-tach pointer ijikeleze ngokuqhelelana ngokweqile. Lapho i-pollictor yewashi ijikeleza kancane kwindlela yewashi bese isikhombisi sisondela iphuzu elifanayo, umpheki wesifunda ozohlanganiswa uvaliwe ngokushesha, ukuze ama-generator amasethi amabili ahambelana. Ukushintshwa kwe-chronograph esihlangene
Okwesithathu, yini okufanele inakeke lapho kufezekisa ukubonwa kwe-quxtaposition ye-quapi-sychchrous of the generator?
I-Quasi-synchronous parallel isebenza ngokusetshenziswa kwezandla, noma ngabe ukusebenza kubushelelezi futhi okuhlangenwe nakho kwe-opharetha kunobudlelwano obuhle, ukuze kuvinjelwe ukufana okuvumelanayo okuhlukile, amacala amathathu alandelayo awavunyelwe ukuvala.
1. Lapho pointer yetafula elivumelanayo livela egxuma ligxuma, ngoba lingavunyelwa ukuvala, ngoba kungahle kube khona into yamakhasethi ngaphakathi kwetafula elivumelanayo, elingabonisi imibandela efanelekile yama-juxtaposition.
2. Lapho itafula elivumelanayo lijikeleza ngokushesha okukhulu, libonisa ukuthi umehluko wemvamisa phakathi kwesethi ye-generator nenye isethi ye-generator mkhulu kakhulu, ngoba isikhathi sokuvala isifunda kunzima ukukwazi Ngasikhathi sinye, ngakho-ke akuvunyelwe ukuvala ngalesi sikhathi.
3. Uma isipoti sewashi sima ngasikhathi sinye, akuvunyelwe ukuvala. Lokhu kungenxa yokuthi uma imvamisa yomunye we-generator isetha kungazelelwe ngesikhathi senqubo yokuvala, kungenzeka ukwenza umpheki wesifunda usondele nje endaweni engavumelani.
Okwesine, kanjani ukuguqula isimo samandla abuyisela emuva amayunithi afanayo?
Lapho ama-generator womabili angenayo angenzi lutho, kuzoba nomehluko wemvamisa kanye nomehluko wamandla kagesi phakathi kwamasethi amabili. Nakuthuluzi lokuqapha lamayunithi amabili (ama-Ammeter, amamitha wamandla, imitha ye-Power Factor), kuboniswa imitha yangempela yamandla ahlukahlukene I-Voltage, eguqulwa kanjena:
