Abstract: Low voltage jenareta seti pari zvino isarudzo yesimba rekukurumidzira kune vazhinji vashandisi, uye iyi modhi inowanzo reva iyo inowanzo shandiswa 230V/400V dhiziri seti pamusika.Nekudaro, mune dzimwe nzvimbo, nekuda kwechinhambwe pakati pekamuri yejenareta yedhiziri uye midziyo yemagetsi, kudonha kwemagetsi kunogona kuitika, zvichikonzera kusakwanisa kushandisa magetsi kazhinji, uye mumatambudziko akaoma, kunyange kupisa midziyo yemagetsi.Naizvozvo, kune vashandisi vakatotenga yakaderera-kudzvanya dhiziri seti, kutora matanho ekuvandudza kubva kuderera-kudzvanya kusvika kune yakakwirira-kudzvanywa inova yakanakisa sarudzo, kuti usarase yepakutanga yakaderera-kumanikidza generator seti uye kukonzera kurasikirwa kukuru kwehupfumi.
1, Kuenzanisa zvakanakira uye kuipa kwepamusoro uye kuderera kudzvinyirira
1. Zvakanakira zve high-voltage jenareta seti:
(1) Simba rejenareta rinogona kuwedzerwa, uye simba repamusoro-soro rejenareta rejenareta rinogona kusvika kune zviuru zvakawanda, kana kunyange makumi ezviuru zve kilowatts.Izvi zvinodaro nekuti, kana uchiburitsa simba rimwechete, ikozvino ye-high-voltage jenareta inogona kuve diki pane iyo yepasi-voltage jenareta.Saka high-voltage jenareta windings inogona kushandisa madiki waya madhayamita.Somugumisiro, iyo stator mhangura yekurasikirwa kwe-high-voltage generator ichavawo duku kudarika ye-low-voltage generator.Kune majenereta emagetsi epamusoro, kana uchishandisa simba rakadzika-voltage, yakakura stator slot inodiwa nekuda kwekudiwa kwetambo dzakasimba, zvichiita kuti dhayamita yakakura ye stator core uye yakawanda yakawanda yejenereta yose;
(2) Kune majenareta makuru emagetsi, majenereta emagetsi anoshandisa simba shoma uye midziyo yekuparadzira pane yakaderera-voltage jenereta, uye ine kurasikirwa kwemutsara wakaderera, iyo inogona kuchengetedza imwe huwandu hwekushandisa simba.Kunyanya 10KV high-voltage jenareta, vanogona kushandisa zvakananga grid magetsi, izvo zvinoderedza mari mumidziyo yemagetsi, kurerutsa kushandiswa, uye kuderedza chiyero chekutadza.
2. Zvakaipa zve-high-voltage generator seti
(1) Mutengo wemagetsi ejenareta wakakwira, uye mutengo wezvinhu zvine chekuita nekudzivirira uchawedzerawo zvinoenderana;
(2) Zvinodiwa zvenzvimbo yekushandiswa kwemajenareta zvakakwirira zvakanyanya kupfuura izvo zvepasi-voltage jenareta;
2, Kusimudzira nzira yemaseti ejenareta
Kune nzvimbo dzinoda high-voltage supply, kunze kwekugoverwa kune yakakwira-voltage generator seti, yakajairika voltage generator seti ine nhanho-up transformers inogona kushandiswa zvakare.
1. Zvakanakira Low Voltage kusvika High Voltage Scheme
(1) Pane maviri kana anopfuura akasiyana magetsi anodiwa panzvimbo yekuvaka, kana kubuda kwemagetsi ejenareta seti inoda kuchinjwa;
(2) (Isolation transformation isolation function) Iyo yakakwirira-voltage inopera ikona transformer, uye matatu-chikamu matatu waya system haina zero mutsara.Pasina mutsara we zero, hapana zero mutsara wekufambisa;Kusiyanisa maharmonics anogadzirwa neasina mutsara mitoro padivi repamusoro-voltage kubva padivi-voltage divi, zvichiita kuti yakaderera-voltage divi ive yakachena uye isingakanganise kushanda kweiyo otomatiki voltage regulator (AVR) mukati mejenareta set, pamwe nekugadzirisa. matambudziko akasiyana-siyana anokonzerwa ne zero line transfer;
(3) Iyo Great Inertia buffering basa rinonyanya kubatsira kutanga mota hombe.Makuru emagetsi anoshandura ane huwandu hukuru hwemhangura, uye iyo hombe yemagineti inotamba basa rekuvharira, ichidzikisa kukanganiswa kwejenareta uye nekuvandudza kudonha kwemagetsi ipapo.
2. Zvakaipa zveParallel Connection Scheme kune Low Voltage Generator Units
Mune 380-415Vac jenareta seti, kana akawanda majenareta seti akabatanidzwa mune parallel kudivi repasi-voltage uye obva asimudzirwa nedanho-up transformer;Muganho wepamusoro unokurudzirwa 7500 kVA, 6000 kW.Kana uchidarika muganho wepamusoro, zvinotevera zvinofanirwa kutariswa:-
Kugona kwe-low-voltage side busbar kunofanira kuva pedyo ne10kA, tichifunga nezvekwanisi yebhazi yekumira kukanganisa kwemhepo uye kupisa kwekupisa mukati me-low-voltage switch (kukwira kwekushisa kwe-low-voltage switch screen);
• Kugumburwa kwemagetsi e-low-voltage switches (kusvika pakugadzirisa kukanganisa), zvakadai kusvika ku65kA uye 100kA;
• Izvo zvinodiwa kuti uverenge kana kuiswa kweanoda kusvika 10000 ampere tambo, low-voltage switch, uye mutengo padivi-low-voltage zvine musoro;
3, Renovation kesi
1. Equipment kuumbwa uye parameters
Mushandisi: Chirongwa muMacau
● Chengetedza simba rekushandisa: UPS + 6000kVA jenareta
Zvose zvechimbichimbi simba: 4500kVA, 3600kW
Voltage system: High voltage 11kV, 50Hz uye yakaderera voltage 415 Vac50Hz
Simba: 4 KTA50-GS8 modhi/1200kW jenareta seti
Jenareta set operation: 3 huru uye 1 backup, ine 1 yakachengeterwa kugadzirisa.Seti yega yega jenareta inogona kubatana kune gidhi remagetsi kuti ishandiswe
Jenareta set voltage: 415Vac/matatu-chikamu/50 kutenderera
● Low voltage switch screen ye generator set:
5000A busbar/80kA1 masekonzi/nhatu-nhanho ina waya/50 kutenderera
Iyo 5000A busbar yakakamurwa kuita zvikamu A uye B
Chikamu A chebhasibar chakabatanidzwa kune maviri generator seti, imwe uye maviri
Chikamu B chebhasibar chakabatana nemaseti maviri ejenareta, 3 uye 4
Kuiswa kwe5000A4 pole interconnection switch yezvikamu zvebhazi A uye B
○ 4 × 2500A mhepo chinja → yakabatana kune mana majenareta seti
3 × 3200A mhepo chinja → yakabatana kune 3 nhanho-kumusoro ma transformer (yakaderera-voltage divi)
● Step-up transformers: 3 seti ye2000kVA11kV/0.415kV
● High voltage switch screen ye transformer: vacuum switch, 15kV600A → yakabatana ne 3 nhanho-up transformers (yakakwirira voltage divi)
2. Ronga kuongorora
(1) Zvina P1500 jenareta zvikamu zvakabatana kune grid kuti ishandiswe, uchishandisa 3+1 jenareta zvikamu zvakafanana.Pasinei nokuti ndeipi chikwata chinoda kugadziriswa, haikanganisi simba rekukurumidzira;
(2) Muchiitiko chekudzima kwemagetsi, majenareta mana anozotanga panguva imwe chete uye obatanidza mana 2500A low-voltage switch uye matatu 200A low-voltage switch padivi-yakadzika-voltage, magnetizing nhanho-kumusoro transformer uye kuvhara matatu 600A yakakwirira. -voltage switches kupa simba kumatunhu akasiyana-siyana;
(3) Chikamu chega chega hachidi ATS otomatiki switching skrini kana yakazvimirira makamuri ejenareta, kuchengetedza mari yakawanda uye yakakosha zviwanikwa zvevhu;Gadzirisa zvisina kunanga matambudziko ekuchengeta zvinhu zvinopfuta moto, mhepo yehutsi, uye ruzha runokonzerwa nekamuri rejenareta;
(4) Mukuyedzwa kwezuva nezuva kwemaseti ejenareta, murairo wekutanga unopihwa kune imwe kana yakawanda yakasarudzwa seti yejenareta nekutevedzera kukanganisa kwe mains, asi mana 2500A low-voltage switch uye matatu 3200A low-voltage switch haivhare;Uye matatu 6000A akakwira-voltage switch akagashira chirongwa chekuyedza uye nemamiriro ezvinhu akadzima kukiya kuvhara.Iyo 5000A busbar yakabatidzwa, uye yega jenareta seti yakawiriraniswa nebhasi.Mushure mekuongorora kwekuenzanisa, 2500A low-voltage switch yakavharwa;Mushure mekuvhara, jenereta seti inopinda muyedzo wakakwana wemutoro.Mushure mokunge muedzo wapera, jenareta yakagadzika inotanga kubvisa kukanganisa kusina kunaka uye nzendo dzekupedzisa muedzo (rwendo rwokutanga 2500A low-voltage switch -3200A low-voltage switch -600A high-voltage switch);
(5) Kana hofisi yemagetsi ichizivisa kudiwa kwekudzimwa kwemagetsi, jenareta seti inogona kubviswa nemaoko kubva kune mains magetsi mushure mekuiswa maererano ne (4), kuitira kuti jenareta seti igone kuvezwa;Kusvikira iyo mains simba radzoreredzwa, iyo jenareta set inowirirana neiyo mains simba pasi pemutoro.Mushure mekubatanidza grid, seti yejenareta inobviswa uye inobuda, uye mushandisi haanzwe kwechinguva kukanganisa kwekudzima kwemagetsi kana kushandura mukati mese maitiro;
