(3) The Great Inertia buffering function e thusa haholo ho qala li-motor tse kholo.Li-transformer tse kholo li na le lisebelisoa tse ngata tsa koporo, 'me mokokotlo o moholo oa makenete o bapala karolo ea ho thibela, ho fokotsa tšusumetso ho jenereithara le ho ntlafatsa ho theoha ha motlakase hang-hang.
2. Mefokolo ea Parallel Connection Scheme bakeng sa Liuniti tsa jenereithara tse tlase tsa Voltage
Ka sete ea jenereithara ea 380-415Vac, haeba lihlopha tse ngata tsa jenereithara li hokahane ka mokhoa o ts'oanang ka lehlakoreng le tlaase la motlakase ebe li matlafatsoa ke transformer ea step-up;Moeli o ka holimo o khothalletsoang ke 7500 kVA, 6000 kW.Ha ho feta moeli o ka holimo, lintlha tse latelang li lokela ho nahanoa:-
Bokhoni ba sebaka se tlase sa motlakase se ka tlase se lokela ho ba haufi le 10kA, ho nahanoa ka bokhoni ba busbar ba ho mamella maqhubu a phoso le kalafo ea mocheso ka har'a sesebelisoa se tlase sa motlakase (ho phahama ha mocheso oa skrineng sa switch ea low-voltage);
• Matla a ho khoptjoa a li-switches tsa "low-voltage" (ho fihlela ho mamella maqhubu a fosahetseng), joalo ka ho fihla ho 65kA le 100kA;
• Hoa hlokahala ho bala hore na ho kenngoa ha lik'hebole tse ka bang 10000 tsa ampere, li-switches tsa low-voltage, le litšenyehelo lehlakoreng la motlakase o tlaase li utloahala;
3. Nyeoe ea ntlafatso
1. Sebopeho sa lisebelisoa le litekanyetso
Mosebelisi: Morero o Macau
● Ho boloka matla a matla: UPS + 6000kVA jenereithara
Kakaretso ea matla a tšohanyetso: 4500kVA, 3600kW
Sistimi ea motlakase: Matla a phahameng a 11kV, 50Hz le voltage e tlase 415 Vac50Hz
Matla: 4 KTA50-GS8 mehlala / 1200kW disete jenereithara
Ts'ebetso ea sete ea jenereithara: 3 ea mantlha le bekapo e le 'ngoe, e le 1 e boloketsoe tlhokomelo.Sete e 'ngoe le e' ngoe ea jenereithara e ka hokeloa ho marang-rang a matla bakeng sa tšebeliso
Jenereithara sete gagamalo: 415Vac / tharo-phase/50 lipotoloho
● Letlapa le tlase la sete ea jenereithara:
5000A busbar / 80kA1 metsotsoana / mekhahlelo e meraro terata e mene / lipotoloho tse 50
Busbar ea 5000A e arotsoe ka likarolo A le B
Karolo ea A ea busbar e hokahane le lihlopha tse peli tsa jenereithara, e le 'ngoe le tse peli
Karolo ea B ea busbar e hokahane le lihlopha tse peli tsa jenereithara, 3 le 4
Ho kenngoa ha 5000A4 pole interconnection switch bakeng sa libaka tsa busbar A le B
○ 4 × 2500A switch ea moea → e hoketsoe ho lisete tse 4 tsa jenereithara
3 × 3200A sesebelisoa sa moea → se hokahane le li-transformer tse 3 tsa mohato o tlase (lehlakoreng la motlakase o tlase)
● Li-transformer tsa ho nyoloha: li-3 tsa 2000kVA11kV/0.415kV
● High voltage switch screen of transformer: vacuum switch, 15kV600A → e hokahantsoeng le 3 step-up transformers (lehlakoreng le phahameng la motlakase)
