Kev sib koom tes ntawm cov tshuab hluav taws xob diesel thiab kev khaws cia hluav taws xob

Kev koom tes ntawm cov tshuab hluav taws xob diesel thiab cov tshuab khaws cia hluav taws xob yog ib qho kev daws teeb meem tseem ceeb los txhim kho kev ntseeg tau, kev txuag nyiaj, thiab kev tiv thaiv ib puag ncig hauv cov tshuab hluav taws xob niaj hnub, tshwj xeeb tshaj yog hauv cov xwm txheej xws li microgrids, cov khoom siv hluav taws xob thaub qab, thiab kev koom ua ke ntawm lub zog rov ua dua tshiab. Cov hauv qab no yog cov hauv paus ntsiab lus ua haujlwm sib koom tes, qhov zoo, thiab cov xwm txheej siv ntawm ob qho:
1, Txoj kev koom tes tseem ceeb
Kev Txiav Plaub Hau Zoo Tshaj Plaws
Lub Ntsiab Cai: Lub kaw lus khaws cia hluav taws xob them thaum lub sijhawm siv hluav taws xob tsawg (siv hluav taws xob pheej yig lossis hluav taws xob ntau dhau los ntawm cov cav diesel) thiab tso tawm thaum lub sijhawm siv hluav taws xob ntau, txo lub sijhawm ua haujlwm siab ntawm cov tshuab hluav taws xob diesel.
Cov Zoo: Txo kev siv roj (kwv yees li 20-30%), txo qhov kev puas tsuaj ntawm lub tshuab, thiab ua kom lub sijhawm txij nkawm ntev dua.
Cov zis du (Kev Tswj Tus Nqi Ramp)
Lub hauv paus ntsiab lus: Lub kaw lus khaws cia lub zog sai sai teb rau qhov hloov pauv ntawm cov khoom thauj, them rau qhov tsis txaus ntawm lub cav diesel pib qeeb (feem ntau 10-30 vib nas this) thiab kev tswj hwm qeeb.
Cov Zoo: Tsis txhob nres lub cav diesel ntau zaus, tswj qhov zaus / voltage kom ruaj khov, tsim nyog rau kev muab hluav taws xob rau cov khoom siv precision.
Pib Dub
Lub hauv paus ntsiab lus: Lub kaw lus khaws cia lub zog ua haujlwm ua lub hauv paus fais fab thawj zaug kom pib lub cav diesel sai sai, daws qhov teeb meem ntawm cov cav diesel ib txwm xav tau lub zog sab nraud los pib.
Qhov Zoo: Txhim kho qhov kev ntseeg tau ntawm kev muab hluav taws xob thaum muaj xwm txheej ceev, tsim nyog rau cov xwm txheej ntawm kev ua tsis tiav ntawm lub zog fais fab (xws li tsev kho mob thiab cov chaw khaws ntaub ntawv).
Kev Sib Koom Tes Rov Ua Dua Tshiab
Lub hauv paus ntsiab lus: Lub cav diesel yog ua ke nrog lub zog photovoltaic / cua thiab lub zog khaws cia kom ruaj khov lub zog hloov pauv tshiab, nrog rau lub cav diesel ua haujlwm ua tus thaub qab.
Cov Zoo: Kev txuag roj tuaj yeem ncav cuag ntau dua 50%, txo cov pa roj carbon.
2, Cov ntsiab lus tseem ceeb ntawm kev teeb tsa kev teeb tsa
Cov kev cai ua haujlwm ntawm cov khoom
Lub tshuab hluav taws xob diesel yuav tsum txhawb nqa hom kev ua haujlwm zaus sib txawv thiab hloov kho rau kev khaws cia lub zog them thiab tso tawm lub sijhawm (xws li raug coj los ntawm lub zog khaws cia thaum lub sijhawm txo qis tsis siv neeg qis dua 30%).
Lub kaw lus khaws cia lub zog (BESS) muab qhov tseem ceeb rau kev siv cov roj teeb lithium iron phosphate (nrog lub neej ntev thiab kev nyab xeeb siab) thiab cov hom fais fab (xws li 1C-2C) los daws cov teeb meem luv luv.
Lub kaw lus tswj hwm lub zog (EMS) yuav tsum muaj ntau hom kev hloov pauv logic (grid connected/off grid/hybrid) thiab dynamic load distribution algorithms.
Lub sijhawm teb ntawm lub bidirectional converter (PCS) tsawg dua 20ms, txhawb kev hloov pauv seamless kom tiv thaiv lub zog rov qab ntawm lub cav diesel.
3, Cov xwm txheej thov ib txwm muaj
Cov kob microgrid
Lub cav photovoltaic + diesel + lub zog cia, lub cav diesel tsuas yog pib thaum hmo ntuj lossis hnub uas muaj huab, txo cov nqi roj ntau dua 60%.
Kev muab hluav taws xob thaub qab rau lub chaw khaws ntaub ntawv
Kev khaws cia hluav taws xob ua qhov tseem ceeb rau kev txhawb nqa cov khoom tseem ceeb rau 5-15 feeb, nrog rau kev sib koom siv hluav taws xob tom qab lub cav diesel pib kom tsis txhob muaj hluav taws xob poob ib pliag.
Lub zog fais fab ntawm cov mines
Cov khoom siv khaws cia hluav taws xob tuaj yeem tiv taus cov khoom hnyav xws li cov excavators, thiab cov cav diesel ua haujlwm ruaj khov hauv qhov ua haujlwm siab (70-80% load rate).
4, Kev Sib Piv Txog Kev Lag Luam (Siv 1MW System Ua Piv Txwv)
Tus nqi pib ntawm txoj kev npaj teeb tsa (10000 yuan) Tus nqi ua haujlwm thiab txij nkawm txhua xyoo (10000 yuan) Kev siv roj (L/xyoo)
Lub tshuab hluav taws xob diesel ntshiab teeb tsa 80-100 25-35 150000
Diesel + lub zog cia (txo 30% ntawm qhov siab tshaj plaws) 150-180 15-20 100000
Lub voj voog rov ua dua tshiab: feem ntau yog 3-5 xyoos (tus nqi hluav taws xob siab dua, qhov rov ua dua tshiab sai dua)
5, Kev ceev faj
Kev sib raug zoo ntawm lub kaw lus: Tus tswj hwm lub cav diesel yuav tsum txhawb kev hloov kho lub zog sai thaum lub sijhawm khaws cia lub zog (xws li PID parameter optimization).
Kev tiv thaiv kev nyab xeeb: Txhawm rau tiv thaiv kev thauj khoom ntau dhau ntawm lub cav diesel los ntawm kev khaws cia hluav taws xob ntau dhau, yuav tsum teeb tsa qhov chaw txiav rau SOC (Xeev ​​​​ntawm Kev Them Nqi) (xws li 20%).
Kev txhawb nqa txoj cai: Qee thaj chaw muab kev pab nyiaj rau lub tshuab hybrid "diesel engine + energy storage" (xws li Tuam Tshoj txoj cai tshiab 2023 energy storage pilot).
Los ntawm kev teeb tsa tsim nyog, kev sib xyaw ua ke ntawm cov tshuab hluav taws xob diesel thiab kev khaws cia hluav taws xob tuaj yeem ua tiav kev hloov kho los ntawm "kev thaub qab ntshiab" mus rau "smart microgrid", uas yog ib qho kev daws teeb meem rau kev hloov pauv ntawm lub zog ib txwm mus rau cov pa roj carbon tsawg. Tus qauv tsim tshwj xeeb yuav tsum tau soj ntsuam kom meej raws li cov yam ntxwv ntawm kev thauj khoom, cov nqi hluav taws xob hauv zos, thiab cov cai.
