Uma usho amandla, funda ukuthi ngingakwazi yini ukukhiqiza amandla angakanani nge-hydro turbine?
Uma usho amandla e-hydro (okuyilokho okuthengisayo), qhubeka ufunda.
Amandla ayikho konke; ungathengisa amandla, kodwa awukwazi ukuthengisa amandla (okungenani hhayi ngokuphathelene namandla amancane angaphansi kwamanzi). Abantu bavame ukukhathazwa ukufuna amandla aphezulu kakhulu avela ohlelweni lwamanzi, kodwa lokhu akubalulekile neze.
Uma uthengisa ugesi ukhokhelwa kuye ngenani lama-kWh (ama-kilowatt-hours) owathengisayo (okungukuthi ngokusekelwe kumandla) hhayi ngamandla owakhiqizayo. Amandla yikhono lokwenza umsebenzi, kanti amandla yizinga umsebenzi ongenziwa ngalo. Kufana kancane namamayela namamayela ngehora; lokhu okubili kuhlobene ngokusobala, kodwa kuhlukile ngokuyisisekelo.
Uma ufuna impendulo esheshayo yombuzo, bheka ithebula elingezansi elibonisa ukuthi kungakanani amandla e-hydro angakhiqizwa ngonyaka wezinhlelo ezahlukene ze-hydro ezinemiphumela yamandla ephezulu ehlukene. Kuyathakazelisa ukuqaphela ukuthi ikhaya 'elijwayelekile' lase-UK lisebenzisa ugesi ongu-12 kWh nsuku zonke, noma u-4,368 kWh ngonyaka. Ngakho-ke inani 'lezindlu zase-UK ezivamile ezisebenza ngamandla' nalo liboniswa izindlu ezisebenza ngamandla' nalo liboniswa. Kukhona ingxoxo eningiliziwe ngezansi yanoma ubani onentshisekelo.
Kunoma iyiphi indawo kagesi osebenzisa amanzi, uma zonke izici zaleyo ndawo sezicatshangelwe futhi 'i-Hands Off Flow (HOF)' ivumelana nomlawuli wezemvelo, ngokuvamile kuzoba nokukhethwa okukodwa kwe-turbine okungcono kakhulu okuzosebenzisa kangcono imithombo yamanzi etholakalayo futhi kuholele ekukhiqizweni kwamandla aphezulu. Ukukhulisa ukukhiqizwa kwamandla okusebenzisa amanzi ngaphakathi kwesabelomali sephrojekthi esitholakalayo kungenye yamakhono abalulekile onjiniyela kagesi osebenzisa amanzi.
Ukuze ulinganisele ukuthi ingakanani amandla uhlelo lwamandla kagesi oluwakhiqizayo ludinga isofthiwe ekhethekile, kodwa ungathola isilinganiso esihle ngokusebenzisa 'i-capacity factor'. I-capacity factor ngokuyisisekelo inani lamandla lonyaka elikhiqizwa uhlelo lwamanzi elihlukaniswe ngobuningi bethiyori uma uhlelo lusebenza ngokukhishwa kwamandla okuphezulu amahora angu-24 ngosuku, izinsuku eziyi-7 ngesonto. Endaweni ejwayelekile yase-UK ene-turbine yekhwalithi enhle kanye nesilinganiso sokugeleza esiphezulu se-Qmean kanye ne-HOF ye-Q95, kungaboniswa ukuthi i-capacity factor ingaba cishe u-0.5. Uma wazi ukuthi ukukhishwa kwamandla okuphezulu okuvela ohlelweni lwamanzi, i-Annual Energy Production (AEP) evela ohlelweni ingabalwa kusukela ku:
Ukukhiqizwa Kwamandla Kwaminyaka Yonke (kWh) = Ukukhishwa kwamandla okuphezulu (kW) x Inani lamahora ngonyaka x isici somthamo
Qaphela ukuthi kunamahora angu-8,760 ngonyaka (ongashayi phansi).
Isibonelo, ezindaweni ezinezinjini eziphansi neziphezulu ngenhla, zombili ezazinamandla aphezulu angu-49.7 kW, i-Annual Hydro Energy Production (AEP) izoba kanje:
I-AEP = 49.7 (kW) X 8,760 (h) X 0.5 = 217,686 (kWh)
Ukukhiqizwa kwamandla kungakhuliswa ngokugcina isikrini sokungena singenazo izinsalela ezigcina ikhanda eliphezulu lesistimu. Lokhu kungafezwa ngokuzenzakalelayo kusetshenziswa isikrini sethu esisha se-GoFlo Travelling esenziwe e-UK yinkampani yethu engudadewethu. Thola izinzuzo zokufaka isikrini sokuhamba se-GoFlo ohlelweni lwakho lwamandla kagesi kulesi sifundo: Ukukhulisa izinzuzo zobuchwepheshe bamandla kagesi kusetshenziswa ubuchwepheshe besikrini sokuhamba se-GoFlo obusha.
