Ni ukubera iki umushinga w'itegeko ry’ingufu zo gucukura amabuye y'agaciro ubabaza cyane?
Inkambi y'ubucukuzi bw'amabuye y'agaciro ni ahantu hatari hakeye, hashobora gukoreshwa ingufu nyinshi: amacumbi, kantine, gutunganya imyanda no gufata neza ibikoresho byose bisaba amashanyarazi adahagarara 24/7.
Igisubizo gakondo cyari gifite inzira imwe gusa - moteri ya mazutu.
Fagitire ya mazutu yiyongera kubabaza. Ibiciro bya lisansi mubisanzwe bingana na 60% -80% yikiguzi cyose cyo gukora amashanyarazi; ahantu hacukurwa amabuye ya kure, ingufu zikomoka kuri mazutu zirashobora kugura inshuro 3-4 igiciro cyamashanyarazi.
Dukurikije imibare ya Xuzhou Zm-Besta ku bijyanye no gusaba ubucukuzi bw'amabuye y'agaciro: umuyoboro umwe w’ikirombe ugereranyije na kilowati 200-400 z'umutwaro, amasaha 12-16 yo gukora buri munsi na miliyoni 0.8-2 kWh yo gukoresha amashanyarazi buri mwaka; ingando ya m 10,000 10,000 yubatswe igereranya 50-80 kW yumutwaro na 15.000-29.000 kWh yo gukoresha amashanyarazi buri kwezi.
Hafi ya mazutu igera kuri 6.71 cente / kilowat ya Amerika, inkambi imwe icukura amabuye y'agaciro irashobora gukoresha kuva ku bihumbi magana kugeza kuri miliyoni imwe y'amadolari ya Amerika kuri mazutu buri mwaka - mbere yo kubara urusaku, ibyuka bihumanya hamwe n’ibitwara peteroli.
Igisubizo cya microgrid ya mazutu ikomoka ku mirasire y'izuba mu nkambi zicukurwamo amabuye y'agaciro (nanone yitwa microcrid ikibanza cya kirombe) ni: gutanga amashanyarazi akomoka ku mirasire y'izuba, kubika ingufu zo kogosha impinga, hamwe na moteri ya mazutu byerekeza kuri “backup yanyuma.” Iki gisubizo cyamashanyarazi adafite amashanyarazi agera kububiko bwa mazutu asimbuza izuba.
Kuva kuri Diesel Grid-Gukora Solar Diesel Hybrid Microgrid Grid-Grid: Ibipimo byingenzi biva mubizamini bya Switchover
"Grid-forming" bivuga isoko isobanura voltage na sisitemu. Mubihe byose bya mazutu, moteri ya mazutu niyo soko yonyine ikora gride; nyuma yo guhinduranya imirasire y'izuba ya hydrogène ya microgrid ikora, inverter ifata voltage / kugenzura mugihe moteri ya mazutu ikora-igahagarara nkibisubizo.
Kugereranya tekinike ya Xuzhou Zm-Besta muburyo bwa kW 100:
Ingamba zingenzi zo guhinduranya zikurikira “izuba ryambere, ububiko bwuzuye, kubika mazutu“: ingufu z'izuba zisagutse zibikwa muri bateri; mugihe cyikirere cyinshi / imvura cyangwa iyo ububiko SOC igabanutse munsi ya 20%, moteri ya mazutu ihita itangira kandi igahuza, hamwe nigihe cyo guhinduranya ms10 ms yo gutanga amashanyarazi adafite imbaraga.
Solar Diesel Hybrid Microgrid Sisitemu yo kuzigama Diesel: Kugera kuri 90%
Numubare abaguzi bita kuri benshi.
Ibiharuro bya Xuzhou Zm-Besta (inkambi ya kilowati 100, ukwezi kwimyaka 5, gukora amasaha 24 ikomeza):
| Ingingo | Diesel-Igisubizo gusa | Solar Diesel Hybrid Microgrid Igisubizo |
| Igiciro cyo gukora buri mwaka | USD 58.750 (mazutu: USD 55.000; kubungabunga: US $ 3,750) | USD 5.833.33 (bisanzwe O&M: USD 1,666.67; amafaranga yo gusimbuza batiri: USD 2.777.78; mazutu yihutirwa: US $ 1.388.89) |
| Kuzigama buri mwaka | – | USD 52,916.67, kugabanuka kwa 90.1% |
| Igiciro kuri kilowati (gikomoka kumafaranga) | Hafi. 6.71 Igiceri c'Amerika / kWt | Hafi. 1.04 US sente / kWt, kugabanuka kwa 84.5% |
Hirya no hino mu nganda, ikoreshwa rya mazutu ryagabanutseho 50% -90%.
Ubushakashatsi bwakozwe: Nyuma ya microgrid ya mazutu ikomoka ku mirasire y'izuba mu bikorwa byo gucukura amabuye y'agaciro ya Zimbabwe yatangiye gukora, ikoreshwa rya mazutu ya buri mwaka ryagabanutseho hejuru ya 90%, bizigama hafi miliyoni 6.948 USD yo gukoresha peteroli ku mwaka; ku kirombe cya Chili, microgrid ya mazutu izuba ryagabanije gukoresha mazutu ikava kuri litiro 980.000 ikagera kuri litiro 468.000 mu mwaka wa mbere, igabanuka rya 52.2%.
Sisitemu Ihamye: Nigute 99.9% Amashanyarazi akomeje kugerwaho
Inkambi z’amabuye y'agaciro ntizihanganira na gato umuriro w'amashanyarazi. Kwizerwa kwizuba rya mazutu ya hydrogène microgrid ishingiye kubishushanyo bitanu:
N + 1 Ubwubatsi bukabije
Imirasire y'izuba, ububiko hamwe na mazutu isubirana hejuru; ingingo imwe yo gutsindwa ntabwo igira ingaruka kumasoko rusange, hamwe nintego yo kwizerwa ya 99.9%.
Gucunga ingufu za EMS
Gukurikirana-igihe nyacyo cyo gusohora izuba, kubika SOC, umutwaro na moteri ya mazutu hamwe no kohereza byikora; ishyigikira gukurikirana kure ukoresheje porogaramu igendanwa / mudasobwa hamwe nigikorwa kitagenzuwe.
Ubushobozi bwo gutangira umukara
Nyuma yo kuzimya sisitemu yuzuye, irashobora gukira vuba yonyine nta nkomoko yimbaraga zituruka hanze.
UPS Amashanyarazi adahagarikwa
Itanga uburinzi budahwitse kumitwaro yoroheje mugihe cyo guhinduranya amashanyarazi, ikuraho igihombo cyamakuru hamwe nibikoresho byigihe.
Kubika ibikoresho no kwihanganira ibikoresho
Batiyeri ya Litiyumu ya fosifate (LiFePO4) ifite ubuzima bwikurikiranya bwa 5.000-8,000 hamwe na SOC igereranya neza ≤3%; imikorere inverter ≥95% na MPPT ikurikirana neza ≥99%; amashanyarazi akomoka ku mirasire y'izuba ni IP55 yagenwe, yoherejwe kurwanya umuyaga wo ku rwego rwa 9 iyo woherejwe, kandi ukora kuva kuri -20 ° C kugeza kuri + 50 ° C, bigatuma ubera ahantu hacukurwa amabuye y'agaciro.
Urugero rw'inganda: microgrid ya mazutu izuba riva mu ruganda rutunganya amabuye ya zahabu mu burengerazuba bwa Ositaraliya rwageze kuri 98.7% mu mezi 18 akora; imirasire y'izuba ya hydrogène microcrids muri rusange igera kubintu byizewe birenga 99.9%.
Ibibazo Bikunze Kubazwa
Q1: Ni ubuhe bwoko bw'ingufu z'inkambi z'ubucukuzi bw'izuba Dizel hybrid microgrid ibereye?
Igisubizo: 20kW - 200kW ifite amashanyarazi akomoka ku mirasire y'izuba bitwikiriye kuva aho umushinga utuye kugeza mu birombe binini; Ibikoresho bya kilowati 100-500 bitanga minini nini ifunguye, itanga hafi 600.000 kWh ku mwaka kandi igasimbuza toni zigera kuri 150 za mazutu.
Q2: Uzahindura kuva kuri mazutu ujya kubika izuba gutera ibikoresho kubura?
Igisubizo: Igihe cyacu cyo guhinduranya ni ms10 ms, munsi yumuryango ibikoresho bishobora kubona; UPS nayo isubiza inyuma imitwaro ikomeye, kubwibyo rero nta guhagarika ingufu mugihe cyo guhinduranya.
Q3: Tuvuge iki ku minsi ikurikiranye ibicu cyangwa imvura?
Igisubizo: Ubushobozi bwo kubika mubusanzwe buringaniye muminsi 3-7 ikurikiranye iminsi yimvura / imvura; iyo ububiko SOC iguye munsi ya 20% cyangwa mubihe bikabije, moteri ya mazutu ihita itangira hejuru yimbaraga.
Ikibazo cya 4: Ni bangahe uzigama mazutu ushobora kwemeza?
Igisubizo: Mubisanzwe 50% –90%. Xuzhou Zm-Besta icyifuzo-cyiza cyo hejuru ni 90.1%; nyabyo biterwa nizuba hamwe nu mutwaro uhetamye.
Q5: Bifata igihe kingana iki kugirango ushireho kontineri ingufu z'izuba sitasiyo?
Igisubizo: Byateranijwe mbere kandi byateganijwe mbere muruganda, birashobora koherezwa kubyara ingufu mugihe cyisaha 1 nyuma yo kugera kurubuga. Kurugero, kontineri ya metero 20 ifata iminota 80 kugirango abakozi 6-bakore neza.
Q6: Sisitemu irashobora gucungwa kure?
Igisubizo: Yego. Ubwenge bwa EMS bushigikira kurebera hamwe nibikoresho gutangira / guhagarika kugenzura ukoresheje porogaramu igendanwa / mudasobwa, bigufasha gukora no kubungabunga.
Niba uteganya igisubizo cyamashanyarazi adafite amashanyarazi cyangwa sisitemu ya kure yingufu zubucukuzi bwamabuye y'agaciro, ahazubakwa, cyangwa inkambi za kure, urakaza neza kuri Xuzhou Zm-Besta.
Kanda kugirango wohereze iperereza, reka dushyireho igisubizo cyingufu zingando zawe hamwe na “Sni mbere, mazutu nka backup yanyuma ”.
