isisitshisele sesikhundla sokugcina isikhundla esingaphansi esinamandla okusuka kumqondiso wokuphakanyiswa ngokuhorizontali wokuphakanyiswa kwe-1P

Ukhulu Lwesikhwama

I-1P (One-in-Portrait) Horizontal Single-Axis Tracking System iyisakhiwo sokuqapha esijwayelekile embonini sezitshalo ze-PV ezisezingeni lokusetshenziswa endaweni eyisicaba kuya endaweni enamagagasi. Ngokujikeleza umzila ngamunye wamamojula usuka empumalanga uye entshonalanga usuku lonke ukuze ulandele i-azimut yelanga, lolu hlelo luthola amandla ngonyaka angama-20% kuya kuma-28% kunesikhungo esifanayo esiqondile sokuthambekela inzuzo ethuthukisa ngqo i-IRR yephrojekthi, inciphise i-

Le sistimu le yadizayiwe ukuthi ibe yinkulu. Umkhakha wokufunda ngasinye uyathola amamodhuli angu-60–120 kubuhlebhu be-1P (amamodhuli aphakanyisiwe ngokwesibhakabhaka emva kwe-torque tube eyodwa), okuyithuluzi ngomotori we-slew-drive oyisikhuba esikhethekileyo esikwenze umkhakha wokufunda ngasinye. Isistimu se-2P sibiza amamodhuli ngasinye kumkhakha wokufunda ngasinye ku-120+ amamodhuli ukuthi sibe nesikhombisa esihle kakhulu.

Izinqubo zokuphatha izinto ezibalulekile:

Isikhombisa se-slew-drive (akasi linear actuator / push-rod): Isikhombisa se-slew-drive sibiza ukuthi kusukela ku-360° ngokuphambana nokuthi kune-torque density enkulu nokuthi akukho backlash, okuyisifundo sokuthi kusukela kwe-high-cycle fatigue environment yokuqonda isithunzi sesolile ngosuku (9,000+ ngeminyaka eyi-25)

ukuqonda isithunzi sesolile ngokuphambana kwe-±0.5°: Ukuphatha ngokuphambana ngokusebenzisa i-inclinometer feedback, akusi open-loop time-based positioning okuthi kushintsha ngaphandle kokuthi kubonakaliswe

I-algorithm yesithunzi + ukubuyela emuva: I-controller iyabala indawo yesithunzi sesolile ngokusebenzisa i-GPS coordinates nezinsuku / isikhathi, nokuthi kune-backtracking logic okuyibeka umkhakha wokufunda ngasinye ngokuphambana kwe-low sun angles ukuthi kususe ukuthi kubonakaliswe kwe-inter-row shading

Ithuba le-Q355B elithunywe ngokwesiliva yomkhosi wokuphatha okunamathuba okukhula kwe-C4: Iyisize ngokulinganisa ubude be-row ne-umkhosi wokuphatha kwezulu esebenzisa umkhosi wokuphatha okungahlinzeki ukuthi i-row ibe yisikhala noma i-module ibe yisikhala

Umsebenzi Wokwenza Izingxenye

Ukuchaza kwesikhundla: Ukubhalwa kwe-slope grade yomkhakha we-N-S kufanele kube ngapansi kwe-5% kusendaweni esihle; uma kubhala ngaphezulu kwe-5% kufanele kubhekwe isikhundla sokubeka amaphumo kusuka emva kwezinye

Amaphuzu okugcina umkhakha: Amaphuzu ka-Cp kwe-geometry yomkhakha wespecifikhi kuzonke izindlela zokugcina, ngokwesifundo sase-wind tunnel noma ukuchaza kwe-CFD

Ukubhalwa kwe-torque tube: Ukubhalwa kwe-torsional stiffness ukuze ubhekiswe ukuthi umkhakha ushale ngapansi kwe-1° phakathi kwezinhlobo zokugcina, ukungavunywa ukuthi umkhakha ushale ngaphandle kwezinhlobo futhi ukuthi iglashe ibe nemiphumela yezinkinga

Ukuvakalisa kwezifunda: Ukuzibonakalisa ukuthi izimali zokuphinda-phinda nezimali zokubuyela ngaphandle zokufana nge-EN 1997-1, okudinga ukuthi kubonakaliswe ukuthi izimali zokudonsa zizoba yizimali ezinkulu ngokudonsa kwesikhombiso

Ukuvavanya ukuphakanyiswa kweziqu: Ukusimulatha kwe-algorithm yokubuyela emva kuzo konke amazwi aphakathi kwezinsuku zomnyaka wokuqala ukuze kubonakalise ukuthi ukuphakanyiswa okuncane kweziqu akukho phansi kweziqu ngaphandle kokugcina ukuthi kungabikho ukugcina kweziqu

Umsebenzi wokufaka

Isifundo Secala: Iphrojekthi Ye-Tracker engu-80MW 1P ENyakatho Kapa, eNingizimu Afrika

Inselele: Indawo eyisicaba enamagceke amaningi ane-DNI ephezulu (ama-2 200+ kWh/m2/ngonyaka). Isidingo sephrojekthi sokuthola inzuzo engama-25% phezu kokuthambekela okuqinile ukuze kuhlangatshezwane nemodeli yezezimali ye-PPA. Umoya ovunguzayo ufinyelela ku-35 m/s phakathi nenkathi yeziphepho zasehlobo.

Isiphumo: Isithuthi sasezulwini sokugcina isikhombisa esisodwa, isithuthi se-torque se-Ø219mm, isithuthi sokugcina, isibonelo sesikhombisa sezulu nesikhipha kwe-GPS nokubuyela emuva. Isteel ye-Q355B ephakanyisiwe ngokuphakanyiswa kwesiliva, ukuchitha kwe-C4. Isithuthi sokugcina esihlanganisa izinkampani. Amamodi angu-90 ngomthambo, 2×45 okungabona ngokwesikhombisa esihlangothile. Ukugcina okuzokwenza ngokuzenzakalelayo kwezinyawo zokuhamba kufika ku-25 m/s.

Isiphumo: Kuthathwe ukuthi kukhona ukuvutha kwe-26.4% ngonyaka ngaphezu kwezinkampani ezifixed-10° ezingaphansi kwesiqondiso esifanayo. Akukho mlando wokugcina kwezinkampani ngaphakathi kwezinkampani kuthathwe ngokuphathwa kwe-pyranometer emhlabeni. Izindlela zokugcina kwezinyawo zokuhamba zingaba yizingu-12 ngonyaka; akukho mlando wokugcina kwezinkampani noma kwezithuthi emva kwezinyaka ezintathu zokusebenza.

Imibuzo Evame Ukubuzwa

Umbuzo: I-imeya yokubuyela emuva yezinkampani ngaphezu kwezinkampani ezifixed tilt iyiphi?

Kusite esinamandla amaningi (2,000+ kWh/m²/nyaka), ipremiyamu yezinkampani ($0.04–0.07/Wdc) isebenza ngokubuyela emuva ngeminyaka eyi-3–5 ngokwesiphumo sokuvutha esikhulu. Lokhu kuyisibonelo sokusite — kusite esincane amandla (<1,500 kWh/m²/nyaka), imeya yokubuyela emuva ibuyela emuva ngeminyaka eyi-6–8, futhi izinkampani ezifixed tilt zingaba zinzima kakhulu.

Umbuzo: Ukubuyela emuva kusebenza kanjani futhi kuyimfihlele kuphi?

Ngemva kwezinsuku zokuphela kwezinsuku zokubeguza, lapho isibonelo sesolwandle sisebenza ngokuphelele, umqondisi wokuqala uyabeka umbiko emuva kwawo. Ukubuyela emuva kuyenza amaqhina yonke ukuba yibe ngokuphelele kumlando ngamaxesha aya, okuyisivumelwano sokugcina ukuthi kungabi nombiko, futhi kusakwa ukuthi kufanele kubhekwe kuzo. Isiphumo esiyindawo kukukhula kwe-energi ngomso kanye nekuphela kwezinsuku kodwa kuvikela ukuthi kungabi nembiko yezinkulungwane ezingu-5–8% eyakwenzeka ngokwesibonelo.

Umbuzo. Kufanele kwenziwe yini ukuchaphaza isistimu yokuhamba?

Amaslew drives ayisikhumba esihlukile, esihlukile ngokusebenzisa igrease, kufanele kubhekwe ngeminyaka emibili futhi igrease iyengezwe uma kudingeka. Umoto wokuhamba uyisikhumba esisodwa ngokuphelele (IP65) nokuthi yisikhumba se-DC esingasiza kakhulu. Isiqhelo sesikhumba sesi-5 sayisho ukuthi sisikhumbela umoto, isigxilo, kanye nezikhiyeli zokuhlela.
