A Sisitemu yo Guhindura Imbaraga (PCS)ni imbaraga nyinshi zifite ingufu za elegitoronike zagenewe gukoreshwa - igipimo cya sisitemu yo kubika ingufu za batiri. Ifasha guhindura imiterere yingufu zamashanyarazi ningufu zerekezo zombi, zishyigikira ingufu za DC kugeza 1500V. PCS ikoreshwa cyane muri sisitemu yo kubika ingufu no kubyara ingufu zishobora kongera ingufu.
Hagati yabateri yo kubika ingufuna gride y'amashanyarazi, nikintu cyibanze gifasha urujya n'uruza rw'ingufu z'amashanyarazi hagati ya sisitemu yo kubika ingufu na gride y'amashanyarazi. Ikoreshwa mugucunga bateri kugirango ikore neza AC / DC mugihe cyo kwishyuza / gusohora kandi ikora imirimo yingenzi yo guhinduranya ingufu zamashanyarazi zombi no kugenzura sisitemu.
Uburyo PCS ikora
Ihame shingiro ryakazi rya PCS nugushikira ibyerekezo byombi no guhindura ingufu zamashanyarazi: hagati yimpande za AC na DC, binyuze muguhinduranya kugenzura ibikoresho bya semiconductor power, ingufu za AC ziva muri gride zikosorwa mumashanyarazi ya DC kugirango yishyure bateri; cyangwa ingufu za DC ziva muri bateri zihindurwamo ingufu za AC kugirango zigarure kuri gride. Ubu buryo bugengwa na sisitemu yo kugenzura microgrid, ishobora gukora imbaraga zihoraho (PQ) cyangwa amabwiriza ahoraho (CC) kugirango igenzure neza ingufu zumuriro wumuriro wa batiri no gusohora (nko kogosha impinga no kuzuza ikibaya), kandi icyarimwe bikorohereza ihindagurika ryingufu zituruka kumasoko yimihindagurikire nkingufu zumuyaga na foto yumuriro.
Mu mashanyarazi ya gride, sisitemu yo kugenzura ingufu (PCS) ifite uruhare runini:
1. Kubungabunga imikorere ihamye ya gride: Gutanga ingufu zokugarura mugihe cya gride idahungabana, kurinda umutekano wa bateri binyuze mumatumanaho hamwe na sisitemu yo gucunga bateri (BMS), no gufasha amashanyarazi manini - kugirango abone ingufu zamashanyarazi no kuzamura ubukungu binyuze muri PCS.
2. Kurinda umutekano wa batiri: Gukorana na BMS, kwemeza ko bateri zikora mumipaka itekanye no gukumira ingaruka nko kwishyuza amafaranga menshi no gusohora -.
3.
Ibyingenzi nibikorwa bya PCS
PCS (Sisitemu yo Kugenzura Imbaraga) igizwe nibikoresho nka IGBTs (Irembo rya Bipolar Transistors), PCBs (Ikibaho cyacapwe), ninsinga ninsinga. Ibyingenzi nibikorwa byingenzi nibi bikurikira:
Guhindura ingufu zombi:PCS irashobora guhindura umuyoboro utaziguye (DC) kugirango uhindurwe (AC) naho ubundi, bigafasha ingufu zibiri zigenda hagati ya gride, bateri, numuzigo. Kurugero, muri sisitemu yo kubika ingufu, irashobora guhindura gride AC kuri DC kugirango yishyure bateri mugihe cyamasaha yo hejuru -, hanyuma ihindure DC ya batiri kuri AC kugirango igarure kuri gride cyangwa itange imizigo yaho mugihe cyamasaha yumunsi.
Kugenzura Imbaraga Zisobanutse:Binyuze mu buryo bunoze bwo kugenzura algorithms, PCS irashobora guhindura ubunini nicyerekezo cyo kwishyuza no gusohora ingufu mugihe nyacyo, bisubiza neza amabwiriza yoherejwe na gride cyangwa ibimenyetso biva muri sisitemu yo gucunga bateri (BMS), bigatuma imikorere ihinduka kandi ihamye yo guhindura ingufu. Kurugero, irashobora guhindura muburyo bwo kwishyuza no gusohora amashanyarazi, voltage, ninshuro zishingiye kuri gride yimitwaro cyangwa imiterere ya bateri.
Gukwirakwiza ubuziranenge bw'imbaraga:PCS ifite guhagarika guhuza hamwe nibikorwa byindishyi zingufu zumuriro, zishobora kuzamura ubwiza bwimbaraga zisohoka no kugabanya kwivanga kuri gride. Mu mikorere mishya y’ingufu zitanga ingufu, irashobora kandi koroshya ihindagurika ry’ingufu zituruka ku masoko y’amashanyarazi rimwe na rimwe nka Photovoltaque n’umuyaga w’umuyaga, bigatuma amashanyarazi atembera neza kandi bigatuma ubushobozi bwa gride bwo kwakira ingufu zishobora kubaho.
Uburyo bwo Guhindura no Kurinda Imikorere:PCS ishyigikira uburyo bwinshi bwo gukora, harimo gride - ihujwe kandi ikazimya - grid (ikirwa), kandi irashobora guhinduka byihuse kandi bidasubirwaho hagati yuburyo butandukanye. Icyarimwe, ihuza uburyo bwinshi bwo kurinda nka volvoltage, kurenza urugero, ubushyuhe burenze urugero, hamwe no kurwanya ikirwa cya - kugirango habeho imikorere ya sisitemu itekanye mu makosa cyangwa mu bihe bidasanzwe, ikumira ibikoresho byangiritse cyangwa impanuka za gride.
Muri make, PCS ni ikiraro cyingenzi gihuza ububiko bwingufu nogukwirakwiza amashanyarazi, koroshya kohereza ingufu zoroshye, gukoresha neza, no gukora imiyoboro ihamye binyuze muburyo bunoze kandi bwubwenge bwo guhindura no kuyobora.
Ikoreshwa rya PCS
Ukurikije ibintu bitandukanye byakoreshwa, PCS irashobora kugabanywamo ibyiciro bitatu byingenzi: sitasiyo yo kubika ingufu, inganda nubucuruzi, hamwe no gutura. Itandukaniro nyamukuru riri mumashanyarazi asohoka.
Ingufu zo Kubika Ingufu
Kinini - igipimo cyingufu zibika ingufu zifite uruhare runini muri sisitemu yingufu, harimo kugenzura inshuro nyinshi, kugenzura ingufu za voltage, no gusubira inyuma. Imbaraga zabo za PCS mubisanzwe zigera kurwego rwa megawatt cyangwa hejuru, hamwe nubushobozi buva kuri megawatt nyinshi kugeza kuri megawatt amagana. Bafite ibisabwa bikomeye kugirango sisitemu isubizwe vuba kandi igenzure neza, kandi igomba kuba ifite imiyoboro ikomeye - ihuza n’imihindagurikire y’imashini hamwe na - imashini ihwanye n’ubushobozi bwo guhuza ibikorwa kugira ngo imikorere y’amashanyarazi itekanye, ikora neza, kandi ihamye mu gihe kinini -. Nibintu byingenzi byingirakamaro byunganira kubaka gride yubwenge.
Sisitemu yo kubika ingufu mu nganda n’ubucuruzi (PCS)
Urwego rwingufu za sisitemu yo kubika ingufu zinganda nubucuruzi mubisanzwe kuva kuri 50kW kugeza 500kW. Guhura ningorabahizi kandi burigihe - guhindura imitwaro yumuriro nuburyo bukoreshwa, PCS igomba kuba ifite ubushobozi bwo guhindura hejuru ya 98.5% na milisegonda - kugendana amakosa - binyuze mubushobozi. Mugukora neza impinga - kogosha no mubande - kuzuza ingamba zo "kubika amashanyarazi mugihe cyamasaha- no gusohora mumasaha yumunsi," bigabanya neza ibiciro byamashanyarazi kubucuruzi 30% -50%. Icyarimwe, imiyoboro ihindagurika ya gride hamwe nibikorwa byo guhinduranya bidasubirwaho bitanga amashanyarazi ahoraho kumasoko akomeye cyangwa ahakorerwa ubucuruzi, kuzamura cyane kwizerwa kwamashanyarazi no kuba umurinzi wogucunga ingufu zumushinga.
Ububiko bw'ingufu zo guturamo PCS
Ububiko bw'ingufu zo guturamo PCS mubusanzwe iba ifite ingufu kuva 5kW kugeza 10kW. Igishushanyo cyacyo, modular yubushakashatsi itanga uburyo bworoshye bwo kwishyiriraho no guhuza hamwe nimbaraga zitangwa nkingufu zizuba hejuru yinzu. Mu kubika ingufu z'izuba zisagutse ku manywa no gutanga imizigo yo murugo nijoro, bizigama neza hejuru kandi - igiciro cyamashanyarazi. Ikigeretse kuri ibyo, itanga imbaraga zidasubirwaho mugihe cyo guhagarika amashanyarazi, guhora itanga amashanyarazi kumitwaro ikomeye nka firigo, amatara, nibikoresho byitumanaho, bityo bigashiraho igisubizo cyizewe kandi cyigenga murugo.
