Ulungelelaniso phakathi kweesethi zejeneretha ye-diesel kunye nokugcinwa kwamandla

Intsebenziswano phakathi kweesethi zejeneretha ye-diesel kunye neenkqubo zokugcina amandla kuyisisombululo esibalulekileyo sokuphucula ukuthembeka, uqoqosho, kunye nokukhuselwa kwendalo kwiinkqubo zamandla zanamhlanje, ngokukodwa kwiimeko ezifana ne-microgrids, imithombo yamandla egcina amandla, kunye nokuhlanganiswa kwamandla avuselelekayo. Oku kulandelayo yimigaqo yokusebenza ngentsebenziswano, izibonelelo, kunye nemeko yesicelo esiqhelekileyo kwezi zimbini:
1. Indlela yentsebenziswano engundoqo
Incopho yokucheba
Umgaqo: Inkqubo yokugcina amandla ihlawulisa ngexesha lokusebenzisa umbane ophantsi (usebenzisa umbane ophantsi kakhulu okanye amandla angaphezulu avela kwiinjini zedizili) kunye nokukhupha ngexesha lokusetyenziswa kombane ophezulu, ukunciphisa ixesha lokusebenza komthwalo ophezulu weejenereyitha zedizili.
Izinto eziluncedo: Ukunciphisa ukusetyenziswa kwamafutha (malunga ne-20-30%), ukunciphisa ukuguga kweyunithi, kunye nokwandisa imijikelo yolondolozo.
Imveliso egudileyo (Ulawulo lweRamp Rate)
Umgaqo: Inkqubo yokugcina amandla iphendula ngokukhawuleza ekutshintsheni komthwalo, ukuhlawulela iintsilelo zokulibaziseka kwe-injini ye-diesel (ngokuqhelekileyo i-10-30 imizuzwana) kunye ne-regulation lag.
Izinto eziluncedo: Kuthintele ukumisa rhoqo kweenjini zedizili, gcina i-frequency/voltage ezinzileyo, ilungele ukunika amandla kwizixhobo ezichanekileyo.
Black Start
Umgaqo: Inkqubo yokugcina amandla isebenza njengomthombo wamandla wokuqala wokuqalisa ngokukhawuleza injini ye-diesel, ukusombulula ingxaki yeenjini zedizili zemveli ezifuna amandla angaphandle ukuqala.
I-Advantage: Ukuphucula ukuthembeka kokunikezelwa kwamandla kaxakeka, okufanelekileyo kwiimeko zokungaphumeleli kwegridi yamandla (ezifana nezibhedlele kunye namaziko edatha).
UkuHlaziywa okuHlaziywayo kweHybrid
Umgaqo: Injini ye-diesel idibaniswe ne-photovoltaic / amandla omoya kunye nokugcinwa kwamandla ukuze kuzinziswe ukuguquguquka kwamandla ahlaziyekayo, kunye ne-injini ye-diesel esebenza njenge-backup.
Izinto eziluncedo: Ukongiwa kwepetroli kunokufikelela ngaphezulu kwe-50%, ukunciphisa ukukhutshwa kwekhabhoni.
2, Amanqaku aphambili oqwalaselo lobugcisa
Iimfuno zokusebenza zecandelo
Iseti yejenereyitha yedizili ifuna ukuxhasa imowudi yokusebenza okuguquguqukayo kwaye ilungelelanise ukutshaja kogcino lwamandla kunye neshedyuli yokukhupha (njengokuthatyathwa kugcino lwamandla xa ukucuthwa komthwalo ozenzekelayo kungaphantsi kwama-30%).
Inkqubo yokugcina amandla (BESS) ibeka phambili ukusetyenziswa kweebhetri ze-lithium iron phosphate (ezinobomi obude kunye nokhuseleko oluphezulu) kunye neentlobo zamandla (ezifana ne-1C-2C) ukujamelana nemithwalo yempembelelo yexesha elifutshane.
Inkqubo yolawulo lwamandla (EMS) idinga ukuba ne-multi-mode switching logic (igridi eqhagamshelweyo/ecinyiweyo kwigridi/i-hybrid) kunye ne-algorithms yokuhambisa umthwalo oguqukayo.
Ixesha lokuphendula le-bidirectional converter (PCS) lingaphantsi kwe-20ms, lixhasa ukutshintshwa kwe-seamless ukuthintela amandla okubuyisela umva we-injini ye-diesel.
3, Iimeko zosetyenziso oluqhelekileyo
Isiqithi microgrid
I-Photovoltaic + injini yedizili + ugcino lwamandla, injini yedizili iqala kuphela ebusuku okanye ngeentsuku ezinamafu, inciphisa iindleko zepetroli ngaphezulu kwe-60%.
Gcina unikezelo lwamandla kwiziko ledatha
Ugcino lwamandla lubeka phambili ukuxhasa imithwalo ebalulekileyo yemizuzu emi-5-15, kunye nokunikezelwa kwamandla okwabelwana ngawo emva kokuba injini ye-diesel iqala ukuphepha ukuphuma kwamandla okwethutyana.
Unikezelo lwamandla omgodi
Ukugcinwa kwamandla kunokumelana nemithwalo yempembelelo efana ne-excavators, kunye neenjini ze-diesel zisebenza ngokuzinzileyo kwi-high-effective range (70-80% izinga lomthwalo).
4, Uthelekiso loQoqosho (Ukuthatha iNkqubo ye-1MW njengoMzekelo)
Iindleko zokuqala zesicwangciso soqwalaselo (10000 yuan) Iindleko zokusebenza zonyaka kunye nokugcinwa kwazo (10000 yuan) Ukusetyenziswa kwamafutha (L/nyaka)
Iseti yejenereyitha yedizili 80-100 25-35 150000
Idizili + ugcino lwamandla (30% incopho yokucheba) 150-180 15-20 100000
Umjikelo wokurisayikilishwa: ngokwesiqhelo yi-3-5 iminyaka (ukuba liphezulu ixabiso lombane, kokukhona ukurisayikilishwa kwakhona)
5. Imiqathango
Ukuhambelana kweNkqubo: Umlawuli we-injini ye-diesel kufuneka axhase ukulungiswa kwamandla okukhawuleza ngexesha lokungenelela kokugcinwa kwamandla (njenge-PID parameter optimization).
Ukukhuselwa kokhuseleko: Ukuthintela ukugcwala kwe-injini ye-diesel okubangelwa kukugcinwa kwamandla amaninzi, indawo yokucima i-SOC (iState of Charge) (efana ne-20%) kufuneka imiselwe.
Inkxaso yomgaqo-nkqubo: Eminye imimandla ibonelela ngenkxaso-mali “yenjini yedizili+ugcino lwamandla” inkqubo exubileyo (efana nomgaqo-nkqubo wokulinga wogcino lwamandla waseTshayina wama-2023).
Ngokucwangciswa okufanelekileyo, ukudibanisa kweesethi zejeneretha ye-diesel kunye nokugcinwa kwamandla kunokufikelela ukuphuculwa ukusuka "kwi-backup ecocekileyo" ukuya kwi-"smart microgrid", esisisombululo esisebenzayo sokutshintsha ukusuka kumandla emveli ukuya kwikhabhoni ephantsi. Uyilo oluthile kufuneka luvavanywe ngokubanzi ngokusekelwe kwiimpawu zomthwalo, amaxabiso ombane wendawo, kunye nemigaqo-nkqubo.
