Umzi-mveliso we-PV unentetho: 2018 ngunyaka wokuqala we-fotovoltaic yombane. Esi sivakalisi siqinisekisiwe kwicandelo lefotovoltaic ifotoVoltaic ibhokisi ye-2018 i-Inbing yasasazwa ikhosi yoqeqesho lweTekhnoloji yeTekhnoloji! Abafakeli kunye nabasasazi kwilizwe liphela bahlanganisana e-NUNJJE ukuba bafunde ulwazi ngokucwangcisiweyo ulwazi lokusasaza ulwakhiwo lwamandla e-Photaltaic.
Njengengcali kwicandelo le-phothivoltaic, i-renac ihlala inikezelwe kwiNzululwazi yeFotovoltaic. Kwindawo yokuqeqesha i-nejong, uMlawuli weNkonzo yobuGoce boBugcisa wamenyelwa ukuba abelane nokukhethwa kwamantshontsho kunye neenkonzo ezikrelekrele. Emva kweklasi, abafundi bancedwa ukuba bahlalutya iingxaki eziqhelekileyo zePhotovoltaic zamandla ePhotovoltaic kwaye bafumana indumiso ye-Unimam evela kubafundi.
AMANQAKU:
1. Iscreen severte ayiboniswanga
Uhlalutyo lokungaphumeleli:
Ngaphandle kwegalelo le-DC, i-Inverter LCD yenziwa yi-DC.
OKUNGAZIYO:
. I-voltage yecandelo ihambelana nemitha yelanga.
(2) Isiphelo sentente se-PV sibuyiselwe umva. Itheminali ye-PV ineepali ezimbini, ezisebenzayo nezingalunganga, kwaye kufuneka zihambelane. Abakwazi kuqhagamshelwa kwakhona kunye namanye amaqela.
(3) Ukutshintsha kwe-DC akuvalwanga.
.
.
Isisombululo:
Linganisa i-DC yokufaka i-Inverter kunye noluhlu lwevolthi ye-Multere. Xa i-voltage iqhelekile, i-voltage iyonke yimali yevolthi yecandelo ngalinye. Ukuba akukho voti, emva koko jonga i-DC Switch, ibhloko yesiphelo, isiqwengana sentambo, kunye nezinto ngokulandelelana; Ukuba kukho izinto ezininzi, ukufikelela kuvavanyo ezahlukeneyo.
Ukuba i-inverter isetyenziselwa ixesha elithile kwaye akukho sizathu sangaphandle sifunyenwe, isiphaluka se-INERTERP SHRERT sinemposiso. Nxibelelana nenjineli yezobuchwephesha emva kwentengiso yasemva kwentengiso.
I-2. I-Ininterter ayixhunyiwe kwinethiwekhi
Uhlalutyo lokungaphumeleli:
Akukho nxibelelwano phakathi kwe-inverter kunye negridi.
OKUNGAZIYO:
(1) Ukutshintsha kwe-AC akuvalwanga.
(2) Isiphelo sendlela ye-AC ye-inverter ayixhunyiwe.
.
Isisombululo:
Linganisa i-Ac Retioge Flotter ye-Initter kunye noluhlu lweevolthi ze-Multere. Phantsi kweemeko eziqhelekileyo, isiphelo semveliso kufuneka sibe ne-220v okanye i-380v voltage. Ukuba akunjalo, jonga ukuba i-terminal yoqhagamshelo iyakhutshwa, ukuba i-Ac Switch ivaliwe, kwaye ukuba ukhuseleko lokukhusela ukhuselo luhlulwe.
I-3. I-Inverter PV ngaphezulu
Uhlalutyo lokungaphumeleli:
I-DC Voltage i-alam ephezulu kakhulu.
OKUNGAZIYO:
Inani eligqithisileyo lezinto ezinokubangela ukuba i-voltage igqithe umda wevolthi ye-invereji ye-inverter.
Isisombululo:
Ngenxa yeempawu zobushushu zamacandelo, ukuhla kweqondo lobushushu, ukuphakama kwevolthi. Uluhlu lwevolunti yegalelo le-inverter yenqanaba elinye i-50-600v, kunye noluhlu lwe-voltage ecetywayo luphakathi kwama-350-400. Uluhlu lweevolthi zevolimu ze-Inverter ye-Inverter ye-3 yi-200-1000v. Uluhlu lweevolthi zevolthi liphakathi kwe-550-700v. Kule voti vogege, ukusebenza kwe-inirter iphakame. Xa i-radiation iphantsi ekuseni kwaye ngokuhlwa, inokuvelisa umbane, kodwa ayibangeli i-voltage idlule kumda ophezulu wombane we-inverter, obangela i-alamu kunye nokuma.
4. Impazamo ye-inverter
Uhlalutyo lokungaphumeleli:
Ukunyangwa okunganyangeki kwenkqubo yefotovoltaic umhlaba ungaphantsi kwe-2 megohims.
OKUNGAZIYO:
Iimodyuli zeSolar, iibhokisi zeJunction, iintambo zeDC, iArhente, iintambo ze-AC, njl njl. Izitebhisi ze-PV kunye nezindlu ze-AC zokudinwa zikhululekile, zikhokelela kwi-ingeress yamanzi.
Isisombululo:
Nqamla igridi, i-inverter, jonga ukunganyangeki kwecandelo ngalinye emhlabeni lomhlaba, fumanisa ukuba le ngxaki, kwaye utshintshe.
I-5. Impazamo yeGrid
Uhlalutyo lokungaphumeleli:
I-voltage ye-grid kunye ne-frequency iphantsi kakhulu okanye iphezulu kakhulu.
OKUNGAZIYO:
Kwezinye iindawo, inethiwekhi yasemaphandleni ayikhiwanga kwaye ivoltage yegridi ayikho ngaphakathi kobungakanani bemigaqo yokhuseleko.
Isisombululo:
Sebenzisa i-Multeter ukulinganisa i-voltage yegridi kunye nefreyiti, ukuba iphelile ukulinda igridi ukuba ibuyele kwisiqhelo. Ukuba igridi yamandla iqhelekile, yindawo engaphakathi efumanisa ukusilela kwibhodi yesekethe. Nqamla yonke i-DC kunye ne-AC ye-AC yomatshini kwaye uvumele i-inverter ukukhutshwa kangangemizuzu emi-5. Vala ubonelelo lwamandla. Ukuba inokuphinda iphinde iphinde, ukuba ayinakubuyiselwa, nxibelelana. Injineli yezobuchwephesha emva kokuthengisa.
