Yintoni uMahluko phakathi kwe-PCS kuGcino oluKhulu, loRhwebo kunye noShishino kunye noGcino lwaseKhaya?

Kwiukugcinwa kwamandlaishishini, PCS, okanye Power Conversion System, isiguquli sokugcina amandla.

Ukugcinwa kwebhetri ngokuqhelekileyo kuhlulwe kwiimeko ezintathu zesicelo esikhulu: ukugcinwa okukhulu, ukugcinwa kwezorhwebo kunye nezoshishino, kunye nokugcinwa kwendlu, kunye ne-PCS / inverters ezihambelanayo kwiimeko ezahlukeneyo nazo zihluke kakhulu. Eli nqaku lihlula i-PCS kwisitoreji esikhulu, i-PCS yokugcinwa kwezoshishino kunye nezorhwebo, kunye ne-PCS yokugcina indlu kwiindidi ezine ezibanzi: isikali samandla, iimeko zesicelo, iimfuno zobugcisa, iindleko kunye nexabiso, ngokulandelanayo.

I. Isikali saMandla

IiPC ezinkulu zokugcina:

Umgangatho wamandla uphezulu, ngokuqhelekileyo kwinqanaba le-MW (megawatt), unokuba phezulu njenge-100MW okanye nangaphezulu. Iinkqubo ezinkulu zokugcina amandla zinokugcina ukuya kuthi ga kwii-megawatt-iiyure ezininzi okanye namakhulu eemegawathi-iiyure zamandla ukuze zihambelane neemfuno zogcino lwamandla egridi enkulu, ukufezekisa ukulawulwa kwamaza egridi, ukutshintshwa kwencopho kunye neminye imisebenzi.

I-PCS yokugcina urhwebo nemizi-mveliso:

Amandla ngokubanzi aphakathi kwamashumi e-kW (ekilowatts) kunye nee-MW ezininzi. Isebenza kubasebenzisi bemizi-mveliso kunye nezorhwebo, umthamo wokugcina usuka kumakhulu aliqela ukuya kumawaka aliqela ekWh, osetyenziselwa ukujamelana neerhafu eziphezulu kunye nokuhlangabezana neemfuno zokuthembeka kwamandla.

IiPC zoGcino lwaseKhaya:

Amandla amancinci ngokwentelekiso, aqhele ukuba phakathi kwekW ezimbalwa kunye neshumi elinesibini lekW. Eyona nto isebenzela ukugcinwa kombane kwikhaya lePV kunye namandla kaxakeka,inkqubo yokugcina amandla kwikhayaumthamo jikelele kuluhlu lweekWh ezimbalwa ukuya kumashumi ekWh.

II. Iimeko zeSicelo

IiPC ezinkulu zokugcina:

I-grid-side: ukulungelelanisa unikezelo kunye nemfuno yegridi, ukugudisa imveliso yethutyana yamandla omoya kunye nokuveliswa kwamandla e-photovoltaic, kunye nokuphucula umgangatho kunye nokuzinza kwamandla ombane. Ngokomzekelo, xa isikhululo samandla esikhulu se-photovoltaic sixhunywe kwigridi, inokugcina amandla amaninzi emini kwaye ikhulule amandla ebusuku okanye ngeentsuku ezinamafu.

Ukuxhasa izikhululo zamandla amakhulu: ukusebenzisana nezikhululo zamandla amakhulu obushushu okanye ombane wamanzi ukwenza ummiselo odibeneyo wamaza ombane, uphendule ngokukhawuleza kwimfuno yolawulo lwefrikhwensi yegridi, kunye nokuphucula ukusebenza kolawulo lwamaza ombane wenkqubo yamandla.

I-PCS yokugcina urhwebo nemizi-mveliso:

Ukuchetywa kwepeak kunye nokuzaliswa kweentlambo: abasebenzisi bemizi-mveliso kunye nezorhwebo bagcina umbane ngexesha lokuhamba kwexabiso lombane kwaye bawukhuphe ngexesha lexesha eliphezulu ukunciphisa iindleko zokusetyenziswa kombane. Ngokomzekelo, amaziko edatha ahlawulisa ebusuku kwaye aphume emini ukunciphisa imfuno yamandla aphezulu kwigridi.

Isiqinisekiso sokunikezelwa kwamandla kaxakeka: Ukubonelela ngenkxaso yamandla kaxakeka kwizixhobo eziphambili zamashishini xa igridi yamandla ihluleka, kwaye iqinisekisa ukusebenza okusisiseko kwamashishini kunye nokusebenza okuqhelekileyo kwezibonelelo ezibalulekileyo.

IiPC zoGcino lwaseKhaya:

Inkxaso yokuvelisa amandla e-photovoltaic yasekhaya: isebenza ngokuhambelana nenkqubo ye-photovoltaic yasekhaya yelanga ukuguqula amandla e-DC kumbane we-AC kusetyenziso lwasekhaya, kunye namandla angaphezulu agcinwe kwibhetri ukuphucula ukuzimela kwamandla asekhaya.

Amandla e-Emergency Backup Power: Ibonelela ngokhuseleko lwamandla olusisiseko kumakhaya ngexesha lokuphela kwegridi, ukugcina ukusebenza kwezixhobo ezibalulekileyo ezifana nezibane, iifriji, kunye nezixhobo zonxibelelwano.

Ⅲ. IiMfuno zobuGcisa

IiPC ezinkulu zokugcina:

Ukusebenza koguqulo: ukusebenza kakuhle kokuguqulwa kuyadingeka, ngokubanzi ngaphezulu kwe-95%, ukunciphisa ukulahleka kwamandla kunye nokuphucula uqoqosho lwenkqubo yokugcina amandla.

Isantya sokuphendula: Inokukhawuleza ukuphendula imiyalelo yokuthunyelwa kwegridi, ukulungelelanisa ukutshaja kunye nokukhupha amandla kwii-millisecond ukugcina ukuzinza kwegridi.

Ukuhambelana kwenkqubo: ukuhambelana kakuhle kunye neenkqubo ezinkulu zebhetri yokugcina amandla kunye neenkqubo zegridi eziyinkimbinkimbi, ukulungelelanisa kwiimpawu zebhetri ezahlukeneyo kunye neemfuno zokufikelela kwigridi.

IiPCS zokugcinwa kwemizi-mveliso nezorhwebo:

Ukuthembeka: ukuthembeka okuphezulu, ukunciphisa ixesha lokuphumla, ukuhlangabezanaishishini kunye nezorhweboimveliso eqhubekayo okanye iimfuno zokusebenza, zifuna umndilili omde ongenaziphene.

I-Power Factor Regulation: Ilawula ngokufanelekileyo into yamandla, iphucula umgangatho wamandla kubasebenzisi bemizi-mveliso kunye nezorhwebo, kunye nokunciphisa inkcitho yombane wenkampani ngembuyekezo yamandla asebenzayo.

IiPC zogcino lwasekhaya:

Ukhuseleko: ngenkqubo egqibeleleyo yolawulo lwebhetri ukuthintela ukutshajiswa kakhulu, ukukhupha kakhulu kunye nokujikeleza okufutshane kweebhetri ukuqinisekisa ukhuseleko lomntu kunye nepropathi yabasebenzisi basekhaya.

Ukusebenziseka ngokulula: kulula ukusebenza kunye nokugcina, kunye ne-interface elula kwaye kulula ukuyiqonda, kulula ukuyifaka kunye nokudibanisa kwinkqubo yamandla endlu.

Ⅳ. Iindleko kunye namaxabiso

IiPC ezinkulu zokugcina:

Iindleko ziphezulu, namaxabiso anokuthi abe kumawaka eedola ngekilowatt nganye. Amandla aphezulu, iimfuno zobugcisa ezintsonkothileyo, kunye nokuveliswa kwemveliso ngobuninzi kukhokelela kwi-R&D ephezulu, imathiriyeli ekrwada, kunye neendleko zemveliso, kodwa amaxabiso ehla ngokuthe ngcembe ngeziphumo zesikali kunye nenkqubela phambili yetekhnoloji.

I-PCS yokugcina urhwebo nemizi-mveliso:

Iindleko kunye nexabiso liphakathi kwe-PCS enkulu yokugcina kunye ne-PCS yokugcina indlu, kwaye ixabiso nge-kW nganye linokuba malunga ne-1000 - 5000 yeedola. Ixabiso lichaphazeleka ngamandla, umsebenzi, uphawu kunye nezinye izinto, ukubuyiswa kotyalo-mali yinto ebalulekileyo kubasebenzisi bezoshishino kunye nezorhwebo ukuba baqwalasele ukuthenga.

IiPC zoGcino lwaseKhaya:

Ixabiso liphantsi ngokwentelekiso, kwaye ixabiso nge-kW nganye linokusuka kumakhulu ambalwa eedola ukuya kwi-2,000 yeedola. Amandla amancinci, umsebenzi ulula, kunye nokwandiswa kwemarike yokugcina amandla asekhaya, ixabiso lilindeleke ukuba lincitshiswe ngakumbi ukuphucula ukwamkelwa kwabasebenzisi bendlu.

I-PCS enkulu yokugcina igridi enkulu kunye nezicelo zesikhululo samandla, amandla aphezulu, iimfuno ezingqongqo zobugcisa, iindleko eziphezulu; Imizi-mveliso kunye neyorhwebo yokugcina PCS iinkonzo zoshishino kunye nezorhwebo incopho ukucheba kunye likaxakeka, amandla aphakathi, ukuthembeka enzima, njl, ixabiso eliphakathi; i-PCS yokugcina indlu ye-PV yasekhaya kunye nokusetyenziswa ngokukhawuleza, amandla amancinci, ukhuseleko lwenqaku kunye nokulula kokusetyenziswa, ixabiso eliphantsi.
