Ukwakheka Nokuhlukaniswa Kwezinhlelo Zokukhiqiza Amandla E-Photovoltaic Axhunywe Igridi

Ukuhlukaniswa kweigridi-ixhunyiweamasistimu wokukhiqiza amandla we-photovoltaic

Amasistimu wokuphehla amandla e-photovoltaic axhunywe kwigridi angahlukaniswa abe amasistimu axhumene negridi aphikisanayo, amasistimu axhumeke kugridi angaphambanisi, amasistimu axhumeke kugridi, amasistimu axhumeke kugridi ye-DC kanye ne-AC, kanye nezinhlelo ezixhunywe igridi yesifunda ngokuya ngokuthi ugesi amandla athunyelwa ohlelweni lwamandla.

1. Uhlelo lokuphehla amandla oluxhunywe kwigridi ephikisanayo

Lapho amandla akhiqizwa uhlelo lokukhiqiza amandla elanga le-photovoltaic anele, amandla asele angathunyelwa kugridi yomphakathi;lapho amandla anikezwa uhlelo lokukhiqiza amandla elanga le-photovoltaic enganele, igridi yamandla inikeza amandla kumthwalo.Njengoba amandla anikezwa igridi ngokuphambene negridi, ibizwa ngokuthi i-countercurrent photovoltaic power generation system.

2. Isistimu yokuphehla amandla exhunywe kwigridi ngaphandle kwe-countercurrent

Ngisho noma uhlelo lokukhiqiza amandla elanga le-photovoltaic lukhiqiza amandla anele, alunikezi amandla kugridi yomphakathi.Kodwa-ke, lapho uhlelo lokukhiqiza amandla elanga le-photovoltaic lunikeza amandla anganele, luzonikwa amandla yigridi yomphakathi.

3. Ukushintsha uhlelo lokuphehla amandla oluxhunywe kugridi

Isistimu yokuphehla amandla exhunywe kugridi inomsebenzi wokushintshwa okuzenzakalelayo kwezindlela ezimbili.Okokuqala, lapho uhlelo lokukhiqiza amandla e-photovoltaic lukhiqiza amandla anganele ngenxa yesimo sezulu, ukuhluleka kokumhlophe, njll., ukushintshwa kungashintsha ngokuzenzakalelayo ohlangothini lokunikezwa kwamandla kwegridi, futhi igridi yamandla inikezela amandla kumthwalo;okwesibili, lapho igridi yamandla ngokuzumayo ilahlekelwa amandla ngenxa yesizathu esithile, uhlelo lokukhiqiza amandla e-photovoltaic Ingakwazi ukushintsha ngokuzenzakalelayo ukuhlukanisa igridi yamandla ohlelweni lokukhiqiza amandla e-photovoltaic futhi ibe uhlelo oluzimele lokukhiqiza amandla we-photovoltaic.Ngokuvamile, ukushintsha amasistimu okukhiqiza amandla e-photovoltaic axhunywe kugridi afakwe imishini yokugcina amandla.

4. Uhlelo lokuphehla amandla oluxhunywe kwigridi yokugcina amandla

Isistimu yokukhiqiza amandla e-photovoltaic exhunywe kugridi enedivayisi yokugcina amandla iwukumisa idivayisi yokugcina amandla ngokuvumelana nezidingo ezinhlotsheni ezibalulwe ngenhla zezinhlelo zokuphehla amandla e-photovoltaic ezixhunywe kugridi.Amasistimu we-Photovoltaic anamadivayisi okugcina amandla asebenza kakhulu futhi angasebenza ngokuzimela futhi anikeze amandla emthwalweni ngokujwayelekile lapho kukhona ukuphuma kwamandla, umkhawulo wamandla noma ukwehluleka kugridi yamandla.Ngakho-ke, uhlelo lokuphehla amandla kagesi we-photovoltaic oluxhunywe kugridi olunomshini wokugcina amandla lungasetshenziswa njengohlelo lokuphakelwa kukagesi ezindaweni ezibalulekile noma imithwalo yesimo esiphuthumayo njengokunikezwa kwamandla okuxhumana okuphuthumayo, imishini yezokwelapha, iziteshi zegesi, inkomba yendawo yokuphuma nokukhanyisa.

5. Uhlelo olukhulu lokuphehla ugesi oluxhunywe kugridi

Isistimu yokukhiqiza amandla e-photovoltaic enkulu exhunywe kugridi yakhiwe amayunithi amaningi okukhiqiza amandla e-photovoltaic axhumeke kugridi.Iyunithi ngayinye ekhiqiza amandla e-photovoltaic iguqula amandla e-DC akhiqizwe amaseli elanga abe amandla angu-380V AC ngesiguquli esixhunywe kugridi ye-photovoltaic, bese iwaguqulela amandla angu-10KV AC aphezulu ngesistimu ye-booster.Ibe isithunyelwa ku-35KV transformer system bese ihlanganiswa namandla angu-35KV AC.Kugridi yamandla kagesi aphezulu, amandla angu-35KV AC aphezulu aguqulwa abe amandla angu-380~400V AC ngohlelo lokuya phansi njengento eyisipele yamandla kagesi esiteshini samandla.

6. Uhlelo lokuphehla ugesi olusabalalisiwe

Isistimu yokuphehla amandla e-photovoltaic esabalalisiwe, eyaziwa nangokuthi ukukhiqizwa kwamandla asabalalisiwe noma ukuphakelwa kwamandla asabalalisiwe, ibhekisela ekucushweni kwamasistimu amancane okuphakela amandla e-photovoltaic esizeni somsebenzisi noma eduze nesizinda sokusetshenziswa kwamandla ukuze kuhlangatshezwane nezidingo zabasebenzisi abathile futhi kusekelwe umnotho inethiwekhi yokusabalalisa ekhona.ukusebenza, noma kokubili.

7. Isistimu ye-microgrid ehlakaniphile

I-Microgrid ibhekisela ohlelweni oluncane lokuphehla amandla nokusabalalisa olwakhiwe imithombo yamandla esabalalisiwe, amathuluzi okugcina amandla, amadivaysi okuguqula amandla, imithwalo ehlobene, imishini yokuqapha nokuvikela.Kuwuhlelo olukwazi ukubona ukuzithiba, ukuvikelwa kanye nokuvikela.Isistimu yokuzimela ephethwe ingasebenza ngokuhlanganyela negridi yamandla yangaphandle noma ngokuhlukana.I-microgrid ixhunywe ohlangothini lomsebenzisi futhi inezici zezindleko eziphansi, i-voltage ephansi kanye nokungcola okuphansi.I-microgrid ingaxhunywa kugridi yamandla amakhulu, noma inganqanyulwa kugridi eyinhloko futhi isebenze ngokuzimela lapho igridi yamandla ihluleka noma idingeka.

Ukwakhiwa kwesistimu yokukhiqiza amandla e-photovoltaic exhunywe kugridi

I-photovoltaic array iguqula amandla elanga abe amandla e-DC, iwahlanganise ngebhokisi lesihlanganisi, bese iguqula amandla e-DC abe amandla e-AC ngesiguquli.Izinga likagesi lesiteshi samandla se-photovoltaic elixhunywe kugridi yamandla linqunywa ngokuvumelana nomthamo wesiteshi samandla se-photovoltaic esicaciswe ubuchwepheshe bokuxhuma isiteshi samandla se-photovoltaic kugridi yamandla., ngemva kokuba i-voltage iphakanyiswe yi-transformer, ixhunywe kugridi yamandla omphakathi.
