1. Impamvu
Kuki inverter ibaho kurenza urugero cyangwa kugabanuka kwamashanyarazi bibaho?
Irashobora kuba imwe mumpamvu zikurikira:
1)Imiyoboro yaho isanzwe ikora hanze yumupaka wa voltage isanzwe (cyangwa igenamigambi ritari ryo).Kurugero, muri Ositaraliya, AS 60038 igaragaza volt 230 nka voltage nominal grid voltage hamwe na.+ 10%, -6% urwego, bityo imipaka yo hejuru ya 253V.Niba aribyo, isosiyete yawe ya Grid yaho ifite inshingano zemewe zo gukosora voltage.Mubisanzwe muguhindura transformateur yaho.
2)Imiyoboro yaho iri munsi yumupaka hamwe nizuba ryizuba, nubwo byashizweho neza kandi kubipimo byose, bisunika gride yaho hejuru yurugendo.Imirasire y'izuba isohora ibyuma byahujwe na 'Umuyoboro uhuza' hamwe na gride na kabili.Iyi nsinga ifite amashanyarazi arwanya voltage ikora umugozi igihe cyose inverter yohereza ingufu mukwohereza amashanyarazi muri gride.Ibi tubyita 'kuzamuka kwa voltage'.Uko izuba ryanyu ryohereza hanze niko nini izamuka rya voltage bitewe n amategeko ya Ohm (V = IR), kandi niko guhangana na cabling niko kuzamuka kwinshi.
Kurugero, muri Ositaraliya, Australiya Standard 4777.1 ivuga ko izamuka ryinshi rya voltage mugushiraho izuba rigomba kuba 2% (4.6V).
Urashobora rero kugira installation yujuje ubuziranenge, kandi ifite umuvuduko wa voltage ya 4V mugihe cyoherejwe hanze.Imiyoboro yaho irashobora kandi kuba yujuje ubuziranenge kandi ikaba kuri 252V.
Ku munsi mwiza wizuba iyo ntamuntu uri murugo, sisitemu yohereza ibintu hafi ya byose kuri gride.Umuvuduko usunikwa kugeza kuri 252V + 4V = 256V muminota irenga 10 ningendo za inverter.
3)Umuvuduko ntarengwa uzamuka hagati yizuba ryizuba hamwe na gride iri hejuru ya t 2% ntarengwa muri Standard,kuberako kurwanywa muri kabili (harimo na connexion iyo ari yo yose) ni hejuru cyane.Niba aribyo, uwashizeho agomba kuba yarakugiriye inama ko AC cabling yawe kuri gride ikeneye kuzamurwa mbere yuko izuba rishobora gushyirwaho.
4) Ikibazo cyibikoresho bya inverter.
Niba amashanyarazi ya Grid yapimwe ahora murwego, ariko inverter ihora ifite ikosa ryikurikiranya ryikirenga nubwo ingano ya voltage yaba ingana gute, igomba kuba ikibazo cyibikoresho bya inverter, birashoboka ko IGBTs yangiritse.
Gusuzuma
Gerageza Umuyoboro wawe wa Gride Kugirango ugerageze amashanyarazi ya gride yaho, bigomba gupimwa mugihe izuba ryanyu rizimye.Bitabaye ibyo, voltage upima izagira ingaruka kuri sisitemu yizuba, kandi ntushobora gushyira amakosa kuri gride!Ugomba kwerekana ko amashanyarazi ya gride ari menshi nta sisitemu yizuba ikora.Ugomba kandi kuzimya imitwaro minini yose munzu yawe.
Igomba kandi gupimwa kumunsi wizuba nko mu ma saa sita - kuko ibi bizirikana izamuka ryumuvuduko watewe nubundi buryo bwizuba bukikije.
Icyambere - andika ako kanya gusoma hamwe na multimeter.Sparky yawe igomba gufata ako kanya voltage isoma kuri switchboard nkuru.Niba voltage irenze voltage ntarengwa, noneho fata ifoto ya multimeter (byaba byiza hamwe nizuba rikuru ryizuba riva mumwanya umwe ku ifoto imwe) hanyuma wohereze mubiro bishinzwe ubuziranenge bwikigo cya Grid.
Icyakabiri - andika impuzandengo yiminota 10 hamwe na voltage yinjira.Sparky yawe ikenera amashanyarazi ya voltage (ni ukuvuga Fluke VR1710) kandi igomba gupima impuzandengo ya min min 10 hamwe nizuba ryanyu hamwe nimizigo minini yazimye.Niba impuzandengo iri hejuru yumubyigano muto hanyuma wohereze amakuru yafashwe hamwe nishusho yikigereranyo cyo gupima - byongeye nibyiza kwerekana izuba rikomeye.
Niba kimwe mubizamini 2 byavuzwe haruguru ari 'positif' noneho kanda sosiyete yawe ya Grid kugirango ikosore urwego rwumubyigano wawe.
Kugenzura igabanuka rya voltage mugushiraho kwawe
Niba kubara byerekana umuvuduko wa voltage urenga 2% noneho uzakenera kuzamura AC cabling kuva muri inverter yawe kugeza kuri gride Connection Point kugirango insinga zibyibushye (insinga zibyibushye = résistance yo hasi).
Intambwe yanyuma - gupima izamuka rya voltage
1. Niba amashanyarazi ya gride yawe ari meza kandi kubara kuzamuka kwa voltage kutarenze 2% noneho sparky yawe ikeneye gupima ikibazo kugirango hemezwe kubara izamuka rya voltage:
2. Hamwe na PV yazimye, hamwe nizindi nzitizi zose zipakurura, bapima voltage yumuriro utari umutwaro.
3. Koresha umutwaro umwe uzwi wo kurwanya urugero urugero: shyushya cyangwa ifuru / hotplates hanyuma upime igishushanyo kigezweho mubikorwa, bitagira aho bibogamiye nisi hamwe nu mutwaro utanga imizigo kuri switch.
4. Uhereye kuri ibi urashobora kubara voltage igabanuka / kuzamuka mubaguzi binjira hamwe na serivise nyamukuru.
5. Kubara umurongo AC irwanya ukoresheje Amategeko ya Ohm kugirango ufate ibintu nkibice bibi cyangwa kutabogama.
3. Umwanzuro
Intambwe Zikurikira
Noneho ugomba kumenya ikibazo cyawe.
Niba ari ikibazo # 1- grid voltage cyane- noneho icyo nikibazo cya sosiyete yawe ya Grid.Niba uboherereje ibimenyetso byose nabasabye bazasabwa kubikosora.
Niba ari ikibazo # 2- grid nibyiza, izamuka rya voltage ntiri munsi ya 2%, ariko iracyagenda noneho amahitamo yawe ni:
1. Ukurikije isosiyete yawe ya Grid urashobora kwemererwa guhindura inverter yiminota 10 impuzandengo y'urugendo ntarengwa rwo kugereranya agaciro (cyangwa niba ufite amahirwe menshi cyane).Shaka sparky yawe kugirango ugenzure hamwe na Grid Company niba wemerewe gukora ibi.
2. Niba inverter yawe ifite uburyo bwa "Volt / Var" (ibyinshi bigezweho barabikora) - noneho saba uwashizeho kugirango ushoboze ubu buryo hamwe ningingo zashyizweho zasabwe na sosiyete yawe ya Grid - ibi birashobora kugabanya umubare nuburemere bwikigereranyo cya voltage.
3. Niba ibyo bidashoboka noneho, niba ufite 3 icyiciro cyo gutanga, kuzamura kugeza kuri 3 inverter isanzwe ikemura ikibazo - nkuko izamuka rya voltage rikwirakwizwa mubice 3.
4. Ubundi urimo kureba kuzamura insinga zawe za AC kuri gride cyangwa kugabanya ingufu zohereza hanze yizuba.
Niba ari ikibazo # 3- voltage nini yazamutse hejuru ya 2% - noneho niba ari iyinjizwamo rya vuba birasa nkaho ushyiraho sisitemu kuri Standard.Ugomba kuvugana nabo hanyuma ugashakira igisubizo.Bizashoboka cyane cyane kuzamura AC cabling kuri gride (koresha insinga zibyibushye cyangwa kugabanya umugozi hagati ya inverter na gride ihuza).
Niba ari ikibazo # 4- Inverter ikibazo cyibikoresho.Hamagara inkunga ya tekinike kugirango utange umusimbura.
