Inā ʻoe e ʻōlelo nei i ka mana, e heluhelu i ka nui o ka mana e hiki iaʻu ke hana mai kahi turbine hydro?
Inā ʻoe e ʻōlelo nei i ka ikehu hydro (ʻo ia ka mea āu e kūʻai aku ai), e heluhelu.
ʻO ka ikehu ka mea nui loa; hiki iā ʻoe ke kūʻai aku i ka ikehu, akā ʻaʻole hiki iā ʻoe ke kūʻai aku i ka mana (ma ka liʻiliʻi ʻaʻole ma ke ʻano o ka mana hydropower liʻiliʻi). Hoʻopilikia pinepine ka poʻe i ka makemake ʻana i ka mana kiʻekiʻe loa mai kahi ʻōnaehana hydro, akā he mea pili ʻole kēia.
Ke kūʻai aku ʻoe i ka uila, uku ʻia ʻoe ma muli o ka nui o kWh (kilowatt-hola) āu e kūʻai aku ai (ʻo ia hoʻi ma muli o ka ikehu) ʻaʻole no ka mana āu e hana ai. ʻO ka ikehu ka hiki ke hana i ka hana, ʻoiai ʻo ka mana ka wikiwiki e hiki ai ke hana i ka hana. Ua like ia me nā mile a me nā mile-i-ka-hola; ua pili maopopo nā mea ʻelua, akā he ʻokoʻa loa lākou.
Inā makemake ʻoe i kahi pane wikiwiki i ka nīnau, e nānā i ka papa ma lalo nei e hōʻike ana i ka nui o ka ikehu hydro e hana ʻia i hoʻokahi makahiki no nā ʻano ʻōnaehana hydro me nā mana kiʻekiʻe like ʻole. He mea hoihoi ia e hoʻomaopopo he home 'awelika' UK e hoʻohana ana i 12 kWh o ka uila i kēlā me kēia lā, a i ʻole 4,368 kWh i kēlā me kēia makahiki. No laila, ua hōʻike pū ʻia ka helu o nā 'home UK awelika i hoʻohana ʻia' nā home i hoʻohana ʻia. Aia kekahi kūkākūkā kikoʻī ma lalo no kekahi mea hoihoi.
No kekahi kahua hydropower, ke noʻonoʻo ʻia nā ʻano kūikawā a pau o kēlā wahi a ua ʻaelike ʻia ka 'Hands Off Flow (HOF)' me ka mea hoʻoponopono kaiapuni, e loaʻa mau ana kahi koho turbine kūpono hoʻokahi e hoʻohana pono ai i ke kumuwaiwai wai i loaʻa a hopena i ka hana ikehu nui loa. ʻO ka hoʻonui ʻana i ka hana ikehu hydro i loko o ka waihona kālā papahana i loaʻa kekahi o nā mākau koʻikoʻi o kahi ʻenekinia hydropower.
No ke kuhi pono ʻana i ka nui o ka ikehu e hana ai kahi ʻōnaehana hydropower me ka pololei, pono ka polokalamu loea, akā hiki iā ʻoe ke loaʻa kahi hoʻokokoke maikaʻi ma ka hoʻohana ʻana i kahi 'capacity factor'. ʻO ka capacity factor ke kumu o ka nui o ka ikehu i hana ʻia e kahi ʻōnaehana hydro i puʻunaue ʻia e ka maximum theoretical inā hana ka ʻōnaehana ma ka mana kiʻekiʻe loa 24/7. No kahi kahua UK maʻamau me kahi turbine maikaʻi a me ka nui o ke kahe ʻana o Qmean a me ka HOF o Q95, hiki ke hōʻike ʻia he 0.5 ka capacity factor. Ke manaʻo nei ʻoe ua ʻike ʻoe i ka mana kiʻekiʻe loa mai ka ʻōnaehana hydro, hiki ke helu ʻia ka Annual Energy Production (AEP) mai ka ʻōnaehana mai:
Hana ʻIkehu Makahiki (kWh) = Ka hoʻopuka mana kiʻekiʻe loa (kW) x Helu hola i ka makahiki x kumu mana
E hoʻomaopopo he 8,760 mau hola i loko o ka makahiki (ʻaʻole lele).
Eia kekahi laʻana, no nā wahi hoʻohālike haʻahaʻa a me ke poʻo kiʻekiʻe ma luna, ʻo ia mau mea ʻelua he 49.7 kW ka mana kiʻekiʻe loa, ʻo ka Hana ʻEnekini Hydro Makahiki (AEP) penei:
AEP = 49.7 (kW) X 8,760 (h) X 0.5 = 217,686 (kWh)
Hiki ke hoʻonui ʻia ka hana ʻana i ka ikehu ma ka mālama ʻana i ka pale komo mai nā ʻōpala e mālama ana i kahi poʻo ʻōnaehana kiʻekiʻe loa. Hiki ke hoʻokō ʻia kēia me ka hoʻohana ʻana i kā mākou pale huakaʻi GoFlo hou i hana ʻia ma UK e kā mākou hui kaikuahine. E ʻike i nā pono o ke kau ʻana i kahi pale huakaʻi GoFlo ma kāu ʻōnaehana hydropower ma kēia haʻawina hihia: Hoʻonui i nā pono o ka ʻenehana hydropower me ka hoʻohana ʻana i ka ʻenehana pale huakaʻi GoFlo hou.
