2026-02-04

Nangona zombini zisebenza ekuveliseni amandla elanga, ukuveliswa kwamandla elanga agxile kwi-tower-type (CSP) kunye nokuveliswa kwamandla e-photovoltaic (PV) zisebenza ngemigaqo yobugcisa eyahlukileyo ngokupheleleyo, nto leyo ekhokelela kwiiyantlukwano ezibalulekileyo kwiimfuno zazo zobugcisa ze-transformer, iinkcukacha, kunye neendima zenkqubo.

Ngamafutshane: ii-PV transformers "ziiqabane ezinee-inverters," ngelixa ii-tower-type CSP transformers "ziiqabane ezineeseti zejenereyitha ye-turbine yomphunga."

Ukuze kuthelekiswe ngokucacileyo, umahluko ophambili ushwankathelwe kwitheyibhile engezantsi:


Ubukhulu beempawu	Isiguquli seNqaba yamandla elanga (i-CSP)	Isiguquli samandla e-Photovoltaic (PV)	Unobangela Womahluko
1. Indima kunye neSikhundla seNkqubo	Icala lesizukulwana elisembindini: Iqhagamshelwe ngqo kwiiseti yejenereyitha ye-turbo-steamYiyunithi ephambili yokunyusa umgangatho yesityalo, elingana ne-transformer yesityalo esishushu sendabuko.	Isasazwe, Icala Lomthombo: Iqhagamshelwe kwiimveliso ye-inverterIqokelela kwaye yonyusa amandla ukusuka kwiiyunithi ezininzi zokuvelisa (umz., ii-string/central inverters). Isityalo sisebenzisa iiyunithi ezininzi ezinjalo.	Ukuveliswa koMbane oTshisayo xa kuthelekiswa nokuveliswa koMbane osebenzisa i-elektroniki.

Layisha ngeHarmonics ebalulekileyo: Umthombo yi-inverter. Imveliso iqulethe ii-harmonics ezitshintsha rhoqo (umz., amaza e-PWM), ezibeka uxinzelelo olongezelelweyo kwi-insulation, zifuna amandla aphezulu okumelana ne-harmonic.	Ijenereyitha vs. I-Power Electronic Converter.
3. I-Voltage kunye nomthamo	I-Voltage Ephezulu, Umthamo Omkhulu Kakhulu Weyunithi Enye:	I-Voltage esezantsi, Umthamo omncinci weyunithi enye:	Iindawo eziPhakathi, eziNamandla aphezulu xa kuthelekiswa neendawo ezisasazekileyo, eziNamandla aphantsi.
	• I-Voltage: Inyuka ngokuthe ngqo ukuya110kV, 220kV, okanye 500kVyoqhagamshelo lwegridi.	• I-Voltage: Ngokwesiqhelo35kV okanye ngaphantsi(umz., 0.8/35kV).
	• Umthamo:Iyunithi enye ingadlula i-100 MVA, ihambelana novavanyo lomenzi wejenereyitha.	• Umthamo:Ngokwesiqhelo kuluhlu lwe-2-5 MVA, icwangcisiwe ngokwe-array ye-inverter nganye.
4. Imfuneko yoHlanganisa iGridi	Ibonelelainertia yenkqubo kunye nomthamo we-short-circuit, ixhasa uzinzo lwegridi. Kufuneka imelane neempembelelo zempazamo yegridi ezidlulayo.	Isebenza njengeumlandeli wegridi, ezifuna izakhono ezifana neLow Voltage Ride-Through (LVRT). Kufuneka zimelane nokuguquguquka rhoqo kwevolthi kunye namandla.	Inkxaso yeGridi esebenzayo ngokuchasene ne-Passive Grid Adaptation.
5. Uhlobo lweTransformer kunye neTekhnoloji egxile kuyo	Ngokuyintloko i-oyile entywilisiweyo Iitransformer zamandla:	IiTransformers zeStep-Up ezifakwe kwi-Dry-Type okanye ezifakwe kwi-Oyile:	Izixhobo Ezinzima Ezikumgangatho Wemizi-mveliso vs Izixhobo Zonxibelelwano Lwezixhobo Ze-Power Electronics Ezenzelwe Wena.
	• Ingqwalasela:Ukuthembeka okuphezulu, ukusebenza kakuhle, amandla okugqithisa kakhulu(ukuze kuhambelane notshintsho lokuqalisa/lomthwalo we-turbine).	• Ingqwalasela:Ukumelana neHarmonic, ukunyamezela kokujikeleza kobushushu, umlinganiselo wokhuseleko oluphezulu (IP)(idla ngokufakelwa ngaphandle).
	• Ihlala ixhotyiswe ngeItshintshi yeTap ekwi-Load (OLTC)ukuze kulawulwe i-grid voltage ngokuchanekileyo.	• Ihlala isetyenziswaiimpompo ezingasebenziyo kwisekethengezizathu zeendleko.
6. Indawo yokusebenza	Kufana nezityalo zemveli, zihlala zikwi-aisakhiwo esizinikeleyo okanye kwisiseko esiqinileyo sangaphandle, kunye nendawo elawulwayo.	Ngaphandle ngokupheleleyoukuthunyelwa, ochatshazelwe kwiimeko ezinzima (ilanga, umoya/isanti, inkungu yetyuwa, amaqondo obushushu agqithisileyo), efuna ukhuseleko oluphezulu kunye nokupholisa.	Indawo yeZityalo zoMbane vs. Indawo yeSithili.
7. Izixhobo ezincedisayo	Ifuna inkqubo yombane epheleleyo yesikhululo samandla:i-generator circuit breaker, i-excitation transformer, i-assistant transformer, njl. njl.	Ngokuyintloko inxibelelana nezixhobo zombane kunye nezixhobo zokusasaza:ii-inverters, iibhokisi zokudibanisa, iiyunithi eziphambili zeringi, njl. njl.

Izinto ezibalulekileyo:

Iintsapho ezahlukeneyo zeTekhnoloji:

Ii-CSP Transformers ziwela phantsi kodidi "lwezixhobo zokuvelisa umbane ezinkulu zemveli." Uyilo lwazo, imveliso, kunye nemigangatho yovavanyo ihambelana ngakumbi nee-transformers eziphambili zezityalo ezishushu/ezisebenzisa amanzi, zigxininisa ukuqina, ukuthembeka, kunye nokusebenza kakuhle.

Ii-PV Transformers zeze "transformers ezikhethekileyo ze-renewables." Ngokusisiseko zilulwandiso lwe-inverter, olufuna ukulungiswa kwe-inverter harmonic output, iindawo zangaphandle ezinzima, kunye nemijikelo yokuqalisa rhoqo.

Ixabiso kunye nokungena kwiMarike:

I-transformer enye ephambili ye-CSP inexabiso eliphezulu kakhulu, iyimpahla ebalulekileyo kwisityalo, kwaye inemiqobo ephezulu yobuchwepheshe. Ababoneleli bafuna iziqinisekiso zoyilo oluqinileyo, ukwenziwa, kunye neereferensi zeprojekthi.

I-transformer enye ye-PV inexabiso eliphantsi leyunithi, kodwa ubungakanani bemfuno buphezulu, ukhuphiswano lunamandla, lugxininisa kakhulu kulawulo lweendleko, imveliso esemgangathweni, kunye nokuhanjiswa ngokukhawuleza.

Isikhokelo Sokukhetha/Sokuthengisa:

Kumthengi weSolar Power Tower (CSP) Plant, cebisa ii-transformer zamandla ezisebenza kakuhle nezithembekileyo kakhulu ezifakwe kwi-oyile ezine-OLTC. Gxininisa amava aqinisekisiweyo ngezixhobo zokuvelisa ezinkulu kunye nezakhono zoyilo ezikhethekileyo (ukushukuma komhlaba, ukugqithisa).

Kwiklayenti ye-PV Plant enkulu, cebisa ii-transformers ezithatha indawo ephezulu (zohlobo olomileyo okanye ezifakwe ioyile) ezilungiselelwe imithwalo ye-inverter ene-IP ephezulu. Gqamisa iimpawu ezifana nokulahleka okuphantsi, ukumelana ne-harmonic, ukunyamezela imozulu, kunye nezisombululo ezingabizi kakhulu ezenzelwe i-PV.

(Isiguquli se-PV asinakusetyenziswa nje kwiprojekthi ye-CSP, kwaye ngokuchaseneyo.)
