Iyo abafite umutungo wizuba batekereje kwizerwa ryamashanyarazi akomoka kumirasire y'izuba, barashobora gutekereza kumasoko yambere yizuba bagura cyangwa barashobora gukora ubwishingizi bwubuziranenge.Nyamara, inverters yuruganda nirwo shingiro ryibikorwa byumushinga wizuba kandi ni ngombwa kugirango habeho igihe.Twabibutsa ko igiciro cya 5% cyibikoresho mu rugomero rw’amashanyarazi rushobora gutera 90% by’amashanyarazi igihe gito.Kubisobanura, ukurikije raporo ya Laboratoire y'igihugu ya Sandia yo muri 2018, inverters nizo zitera gutsindwa kugera kuri 91% mumishinga minini yingirakamaro.
Iyo inverter imwe cyangwa nyinshi zananiranye, imirongo myinshi ya fotovoltaque izahagarikwa kuri gride, bizagabanya cyane inyungu zumushinga.Kurugero, suzuma megawatt 250 (MW) umushinga wizuba.Kunanirwa kwa inverter imwe imwe ya MW 4 irashobora gutera igihombo kigera kuri MWh 25 / kumunsi, cyangwa kumasezerano yo kugura amashanyarazi (PPA) igiciro cyamadorari 50 / kumunsi, Gutakaza MW 1,250 kumunsi.Niba amashanyarazi ya 5MW yose yahagaritswe ukwezi kumwe mugihe cyo gusana inverter cyangwa kuyisimbuza, igihombo cyinjira muri uko kwezi kizaba US $ 37.500, cyangwa 30% yikiguzi cyambere cyo kugura inverter.Icy'ingenzi cyane, gutakaza amafaranga ni ikimenyetso cyangiza ku mpapuro zerekana ba nyir'umutungo n'ibendera ritukura ku bashoramari b'ejo hazaza.
Kugabanya ibyago byo gutsindwa kwa inverter birenze kugura kurutonde rwabakandida batera inkunga urwego rwa mbere rukora inganda no guhitamo igiciro gito.
Hamwe nuburambe bwimyaka irenga icumi mugutezimbere no gucunga inverter yubunini butandukanye kubakora inganda zikomeye, ndashobora kwizeza ko inverter atari ibicuruzwa.Buriwese utanga isoko afite ibishushanyo mbonera bitandukanye, ibishushanyo mbonera, ibice na software, kimwe nibisanzwe bitari mu bubiko bishobora kugira ubuziranenge bwibibazo no gutanga amasoko.
Nubwo wishingikiriza ku moderi yemejwe itigeze inanirwa gukora neza no kuyitaho, urashobora kuba mukaga.Kuva ibigo bya inverter byotswa igitutu kugirango bigabanye ibiciro byinganda, kabone niyo inverter yuburyo bumwe igereranijwe, igishushanyo kizakomeza kuvugururwa.Kubwibyo, icyifuzo cya inverter cyatoranijwe cyizewe mumezi atandatu ashize gishobora kuba gifite ibice byingenzi byingenzi hamwe nibikoresho bya software mugihe byashizwe mumushinga wawe uheruka.
Kugirango ugabanye ibyago byo kunanirwa kwa inverter, ni ngombwa kumva uburyo inverter yananiwe ningamba zafatwa kugirango izo ngaruka zigabanuke.
22Ibi bice byateguwe kubikorwa bimwe na bimwe, nkubushyuhe nubushyuhe bwamashanyarazi.
Urugero: Niba uruganda rukora inverter rwashizeho IGBT yumuriro wamashanyarazi kugirango rusuzumwe ku bushyuhe bw’ibidukikije bwa dogere 35 ° C, ariko inverter ikora ku mbaraga zuzuye kuri 45 ° C, igipimo cya inverter cyateguwe nuwabikoze ntabwo ari IGBT.Kubwibyo, iyi IGBT irashobora gusaza kandi ikananirwa imburagihe.
Rimwe na rimwe, abakora inverter bashushanya inverter hamwe na IGBT nkeya kugirango bagabanye ibiciro, bishobora no gutuma ubushyuhe buringaniye bwo gukora / guhangayika no gusaza imburagihe.Nubwo bidasobanutse neza, ibi biracyari imyitozo ikomeje nabonye mu nganda zuba mumyaka 10-15.
Ubushyuhe bwo gukora imbere nubushyuhe bwibice bya inverter nibintu byingenzi bitekerezwa kubishushanyo mbonera no kwizerwa.Ibyo kunanirwa imburagihe birashobora kugabanywa nubushakashatsi bwiza bwumuriro, gukwirakwiza ubushyuhe bwaho, kohereza inverteri mubice byubushyuhe buke, no kugena uburyo bwo kubungabunga ibidukikije.
# 2 Ikizamini cyo kwizerwa.Buri ruganda rwashizeho protocole yikigereranyo kugirango isuzume kandi igerageze inverters yinzego zitandukanye.Mubyongeyeho, igihe kigufi cyashushanyijeho ubuzima bushobora gusaba gusimbuka icyiciro gikomeye cyo kugerageza cyimiterere yihariye ya inverter.
# 3 urukurikirane rw'inenge.Nubwo uwabikoze ahisemo ibice bikwiye kugirango akoreshwe neza, ibice ubwabyo birashobora kugira inenge muri inverter cyangwa porogaramu iyo ari yo yose.Yaba IGBTs, capacator cyangwa ibindi bikoresho byingenzi bya elegitoroniki, ubwizerwe bwa inverter yose biterwa numuyoboro udakomeye mubwiza bwurwego rutanga.Ikoranabuhanga ritunganijwe hamwe nubwishingizi bufite ireme bigomba gukorwa kugirango bigabanye ibyago byibintu bifite inenge amaherezo byinjira mumirasire y'izuba.
# 4 Ibikoreshwa.Abakora inverter barasobanutse neza kubijyanye na gahunda zabo zo kubungabunga, harimo gusimbuza ibikoreshwa nk'abafana, fus, imashini zangiza ndetse na switchgear.Kubwibyo, inverter irashobora kunanirwa kubera kudakwiye cyangwa kutayitaho.Ariko, kimwe, barashobora kandi kunanirwa kubera igishushanyo cyangwa gukora inenge zindi-inverters cyangwa OEM ikoreshwa.
# 5 Gukora: Hanyuma, na inverter yakozwe neza hamwe numuyoboro mwiza wo gutanga irashobora kugira umurongo uteranya.Ibi bibazo byumurongo winteko birashobora kugaragara mubice byose byuburyo bwo gukora.Ingero zimwe:
Na none kandi, kugirango ukomeze igihe cyigihe gito nigihe gito ninyungu ndende, ni ngombwa gushiraho inverter yemejwe kandi yizewe.Nka sosiyete y-igice cyizeza ubuziranenge, China Eastern Airlines ntabwo ikunda abayikora, imideli cyangwa urwikekwe kubirango ibyo aribyo byose.Ikigaragara ni uko abakora inverter bose hamwe nuruhererekane rwabo ruzagira ibibazo byubwiza burigihe, kandi ibibazo bimwe bikunze kugaragara kurenza ibindi.Kubwibyo, kugirango ugabanye ingaruka zo gutsindwa kwa inverter, igisubizo cyonyine cyizewe ni gahunda ihamye yo kwizerwa no kwizerwa ryiza (QA).
Kubakiriya benshi b'imishinga minini yingirakamaro ifite ibyago byinshi byamafaranga, gahunda yubwishingizi bwubuziranenge igomba kubanza guhitamo inverter nziza iboneka hashingiwe ku gishushanyo mbonera cyayo, imyubakire, imikorere y’urubuga, hamwe n’amahitamo yihariye, azirikana ikirere kiri ku mbuga. , ibisabwa bya gride, ibisabwa byigihe nizindi mpamvu zamafaranga.
Isubiramo ryamasezerano hamwe na garanti bizashyira ahagaragara ururimi urwo arirwo rwose rushobora gushyira nyir'umutungo mubibazo byemewe n'amategeko mubisabwa garanti.
Icy'ingenzi cyane, gahunda nziza ya QA igomba kuba ikubiyemo ubugenzuzi bwuruganda, kugenzura umusaruro no gupima uruganda (FAT), harimo kugenzura ibibanza no gupima ubuziranenge bwimikorere yihariye ikorerwa kumashanyarazi yizuba.
Ibintu bito bigize ishusho rusange yumushinga wizuba watsinze.Ni ngombwa kutirengagiza ubuziranenge muguhitamo no gushiraho inverters mumushinga wawe wizuba.
