Hlanza i-turbine yamanzi ngamandla angase abe khona noma amandla e-kinetic, bese i-turbine yamanzi iqala ukujikeleza. Uma sixhuma i-generator ku-turbine yamanzi, i-generator ingaqala ukukhiqiza ugesi. Uma siphakamisa izinga lamanzi ukuze sihlanze i-turbine, ijubane le-turbine lizokhula. Ngakho-ke, lapho umehluko wezinga lamanzi umkhulu, kulapho amandla e-kinetic atholakala yi-turbine eba makhulu, futhi kulapho amandla kagesi aguqulwayo eba phezulu. Lesi yisimiso esiyisisekelo samandla kagesi angaphansi kwamanzi.
Inqubo yokuguqulwa kwamandla yile: amandla adonsela phansi amanzi angaphezulu aguqulwa abe amandla e-kinetic okugeleza kwamanzi. Lapho amanzi egeleza nge-turbine, amandla e-kinetic adluliselwa kwi-turbine, bese i-turbine iqhuba i-generator ukuthi iguqule amandla e-kinetic abe amandla kagesi. Ngakho-ke, inqubo yokuguqula amandla omshini abe amandla kagesi.
Ngenxa yezimo zemvelo ezahlukene zeziteshi zamandla kagesi, amandla kanye nesivinini samayunithi ejeneretha kagesi kuyahlukahluka kakhulu. Ngokuvamile, amajeneretha amanzi amancane kanye namajeneretha kagesi kagesi asheshayo aqhutshwa ama-turbine e-impulse asebenzisa kakhulu izakhiwo ezivundlile, kuyilapho amajeneretha amakhulu naphakathi asebenzisa kakhulu izakhiwo eziqondile. Njengoba iziteshi eziningi zamandla kagesi kagesi zikude kakhulu namadolobha, ngokuvamile zidinga ukuhlinzeka ngamandla emithwalweni ngemigqa emide yokudlulisa, ngakho-ke, uhlelo lwamandla lubeka phambili izidingo eziphakeme zokuqina kokusebenza kwamajeneretha kagesi kagesi kagesi: amapharamitha emoto adinga ukukhethwa ngokucophelela; Izidingo zesikhathi sokungabi namandla kwe-rotor zikhulu. Ngakho-ke, ukubukeka kwejeneretha kagesi ...
Ngokuphathelene nesimiso sejeneretha, i-physics yesikole samabanga aphezulu icacile kakhulu, futhi isimiso sayo sokusebenza sisekelwe emthethweni we-electromagnetic induction kanye nomthetho wamandla kagesi. Ngakho-ke, isimiso esijwayelekile sokwakhiwa kwayo ukusebenzisa i-magnetic conductivity efanele kanye nezinto zokuqhuba ukuze kwakhiwe isekethe yamagnetic kanye nesekethe yokungenisa kagesi kagesi okuhlangene ukuze kukhiqizwe amandla kagesi futhi kufezwe injongo yokuguqulwa kwamandla.
Ijenereyitha ye-turbine yamanzi iqhutshwa yi-turbine yamanzi. I-rotor yayo imfushane futhi ijiyile, isikhathi esidingekayo sokuqala kweyunithi kanye nokuxhumeka kwegridi sifushane, futhi ukuthunyelwa komsebenzi kuyaguquguquka. Ngaphezu kokukhiqizwa kwamandla okuvamile, ifaneleka kakhulu kwiyunithi yokushefa ephezulu kanye neyunithi yokulinda ephuthumayo. Umthamo omkhulu wamayunithi ejenereyitha ye-turbine yamanzi ufinyelele kuma-kilowatts angu-800000.
Ijenereyitha yedizili iqhutshwa yinjini yokushisa yangaphakathi. Iyashesha ukuqala futhi kulula ukuyisebenzisa, kodwa izindleko zayo zokukhiqiza ugesi ziphezulu. Isetshenziswa kakhulu njengamandla okusekelayo aphuthumayo, noma ezindaweni lapho igridi enkulu yamandla ingafinyeleli khona kanye neziteshi zamandla ezihambayo. Umthamo usukela kuma-kilowatts amaningana kuya kuma-kilowatts amaningana. Ukukhishwa kwe-torque ku-shaft yenjini yedizili kuncike ekushayweni ngezikhathi ezithile, ngakho-ke izingozi zokuqhekeka kwe-resonance kanye ne-shaft kumele zivinjelwe.
Ijubane lejenereyitha yamanzi lizonquma imvamisa yamandla ashintshanayo akhiqizwayo. Ukuqinisekisa ukuzinza kwale mvamisa, ijubane le-rotor kumele lizinze. Ukuze kuzinziswe ijubane, ijubane le-prime mover (i-water turbine) lingalawulwa ngemodi yokulawula i-closed loop. Isignali yemvamisa yamandla e-AC azothunyelwa iyathathwa isampula bese ibuyiselwa ohlelweni lokulawula olulawula i-engeli yokuvula nokuvala ye-guide vane ye-water turbine ukulawula amandla okukhipha e-water turbine. Ngomgomo wokulawula impendulo, ijubane lejenereyitha lingazinziswa.
