Ina kōrero tātou mō te tāone i te pō, he mea nui ngā rama tiriti i runga i te rori. I ngā tau tata nei, kua piki haere te rongonui o te ariā o te tiaki taiao matomato i waenga i te marea, ā, kua nui te aro ki ngā rama tiriti e whakamahia ana e te rā. Hei whakarite kia taea e ēnei rama tiriti te whakamārama pono i te rori i te pō, me whakaaro tātou ki ētahi tawhā nui tae atu ki te kaha o ngā rama tiriti, te mana o te panera photovoltaic, te kaha o te pākahiko me te pumau o te kaiwhakahaere. Ko te hoahoa me te whirihoranga o te pūnaha rama tiriti rā he mea nui. E pā ana ki te taea te whakamārama i te rori i runga i te tika me te pumau.
He aha me aro atu tātou ki ngā tawhā o te rama tiriti solar
E pā ana ngā panera rā ki te kaha kohikohi pūngao, arā, te roa o te wā e pau ana ki te whakakī katoa i te pākahiko ki te hihi o te rā. Me pā te kaha o te pākahiko LiFePO4 ki te āheinga o te rama tiriti ki te whakahaere tonu i te wā e whakamārama ana i te pō. Mēnā he hē te whirihoranga o ēnei tawhā me ngā wāhanga o ngā pūnaha rama tiriti rā, ka pāngia te mahi noa o ngā pūnaha rama tiriti rā. Hei tauira, mēnā he iti rawa te kaha o te panera rā me te pākahiko, kāore pea e taea e ngā rama tiriti te whakatutuki i ngā hiahia pūngao i te pō, me ētahi atu. Engari, mā te mārama hohonu ki ēnei tawhā ka āwhina i te waihanga i ngā pūnaha rama tiriti rā whai hua, whai whakaaro, me te pumau e whakarato ana i te rama tāone pono.
Tātaihia te tapeke o ngā watt-haora ia rā mō te rama tiriti
Ko te tapeke o ngā hāora-watt ko te pūngao hiko e pau ana i te pūnaha rama tiriti o te rā i ia rā, e pā tika ana ki te kaha o te pākahiko me te kōwhiringa mana o te panera rā. Hei tatau i te paunga pūngao o ia rā (tapeke o ngā hāora-watt) o te rama tiriti, me mōhio koe ki ngā āhuatanga matua e rua: te wattage o te rama i ngā wā rerekē me te maha o ngā hāora whakahaere i ia wā. Ko te tātai mō te tatau i te tapeke o ngā hāora-watt i ia rā koia tēnei: Tapeke o ngā hāora-watt i ia rā = Te paunga hiko 1 (W) × Te maha o ngā hāora mahi i roto i te wā rerekē. Hei tauira, ki te whakaaro he rama tiriti me te wattage o te rama tiriti 100W e mahi ana mō ngā hāora 12 i te rā, me ngā hāora 5 tuatahi e mahi ana i te 100% te mana me ngā hāora 7 whakamutunga e mahi ana i te 50% te mana, kātahi ka tatauhia te tapeke o ngā hāora-watt i ia rā penei: Tapeke o ngā hāora-watt i ia rā = 100W × 5 hāora + 50W × 7 hāora = 850 hāora-watt (Wh). Ka taea te whakamahi i ngā hua tātaitanga i ngā wāhanga e whai ake nei hei whakatau i te kaha o te pākahiko me te mana o te papa rā e hiahiatia ana mō te rama tiriti rā.
Pūhiko o ngā pūnaha rama tiriti pūngao rā – te kaha
Ko te momo pākahiko e taunakitia ana mō te whakamahi i roto i ngā pūnaha photovoltaic solar ko ngā pākahiko huringa hohonu. Kua hangaia ngā pākahiko huringa hohonu mō te utu tere i muri i te tukunga ki ngā taumata pūngao iti, mō te utu tonu me te tukunga mō ngā tau maha. Me nui te pākahiko hei penapena pūngao hei whakahaere i te rama tiriti LED i te pō me ngā rā kapua. Ko te tikanga, ka whakamahia e ngā pūnaha rama tiriti solar ngā pākahiko lithium (LiFePO4). He roa te ora, he pai te haumaru, ā, he teitei te...
Tātaihia te tapeke o ngā hāora watt e whakamahia ana e te rama rama ia rā. Tātaihia te pai o te tahuritanga o te pūnaha hei 95% Tātaihia te hohonutanga o te tukunga o te pākahiko. ka tātaihia ngā pākahiko lithium hei 95% Tātaihia te maha o ngā rā mahi motuhake (arā, te maha o ngā rā e hiahiatia ana e te pūnaha hei mahi me te kore he panera photovoltaic hei whakaputa hiko) Te kaha o te pākahiko e hiahiatia ana (Wh) = Tapeke Watt-haora (ia rā) x Ngā rā o te mana motuhake / 0.95 / Te hohonutanga o te tukunga o te pākahiko huringa hohonu
He rangahau take E-LITE mō ngā pūnaha rama tiriti pūngao-rā
I tēnei wā, kei te mahi tā mātou kiritaki i tētahi kaupapa rama tiriti pūngao-rā. Me whakamahi e te kiritaki he rama tiriti pūngao-rā 115W, kāore e hiahiatia he pūoko me te whakamahi i te whakaitiiti PWM, engari me whakarite he wā whakaitiiti. Ko te mahi motuhake e hangai ana ki te wā e whai ake nei: ko te wā tuatahi he 100% ā, ka haere tonu te mahi mō te 5 hāora; ko te wā tuarua he 50% ā, ka haere tonu te mahi mō te 7 hāora; kotahi noa te wā e hiahiatia ana hei whakamārama i te pō. Te Wā o te Rā (Te Utu).
E 8 mita te whānui o te rori, ā, e 1.5 mita te roa o ngā ara hikoi i ngā taha e rua. E 10 mita te teitei o te pou rama, e 1 mita te roa o te cantilever, ā, e 36 mita te tawhiti i waenganui i te pou rama me te rori, e tutuki ana i ngā whakaritenga o te taumata rama M2. E ai ki ngā hua o te whakatauira rama o E-LITE, e whakaatuhia ana he tino pai te raupapa 115W Omni.、
Ngā haora-watt o
I runga anō i ngā āhuatanga o te kaupapa, i tatauhia e mātou te whakapaunga hiko tuturu penei:
Te whakamahinga katoa o ngā rama tiriti = (115W x 5 hāora) + (57.5W x 7 hāora) = 977.5Wh/rā
Te kaha o
I runga anō i te āhuatanga o te kaupapa, nā te mea ko te maha o ngā wā mahi he kotahi pō anake. Kātahi ka whakamaoritia e mātou tēnei hiahia pūngao.
te kaha o te pākahiko, me te whakaaro ko te ngaohiko o tā mātou pūnaha pākahiko he 25.6V
Te kaha o te pākahiko = Te whakamahinga katoa o ngā rama tiriti 977.5WH×(0+1)/25.6V/95%/95%=42.3AH
Whakamutunga: Ko te kaha o te pākahiko: 25.6V/42A
(ko te kaha o te pūtau pākahiko kotahi he 6AH, nō reira ka whakaawhiwhihia te 42.3AH ki te 42AH
Te kaha o te
1、Te iti rawa o te kaha whakaputa hiko o te papa pākahiko ia rā (ka utua katoatia te pākahiko i roto i te kotahi rā-6 hāora)
25.6x42AH=1075.2WH
2, Te iti rawa o te hiko whakaputa o te papahiko
1075.6WH/6H=179.2W 3、Te whai huatanga o te tahuritanga pūnaha 95%
179.2W/95%=188.63
I runga i ngā hua, ka taea e tātou te whiriwhiri ki te tāuta i te kotahi waeine papa rā 36V/190W (99% te tauwehenga utu haumaru i rahuitia) hei whakatutuki i ngā hiahia pūngao o te kaupapa.
