I-AC frequency ayinxulumananga ngokuthe ngqo nesantya senjini yesikhululo sombane wamanzi, kodwa inxulumene ngokungathanga ngqo.
Kungakhathaliseki ukuba luhlobo luni lwezixhobo zokuvelisa amandla, kufuneka udlulisele amandla kwigridi yamandla emva kokuvelisa amandla, oko kukuthi, i-generator kufuneka idibaniswe kwigridi yokuvelisa amandla. Emva kokudityaniswa kwigridi, idityaniswe negridi yamandla iyonke, kwaye i-frequencies yonke indawo kwigridi yamandla iyafana ncakasana. Okukhona inkulu igridi yamandla, incinci uluhlu lokuguquguquka kwamaza kwaye uzinzile ngakumbi. Nangona kunjalo, i-frequency yegridi yamandla inxulumene kuphela nokuba amandla asebenzayo alungelelanisiwe. Xa amandla asebenzayo aveliswa yisethi yejeneretha inkulu kunamandla asebenzayo ombane, i-frequency jikelele yegridi yamandla iya kwanda, kwaye ngokufanayo.
Ibhalansi yamandla esebenzayo ngumba omkhulu wegridi yamandla. Ngenxa yokuba umthwalo wamandla wabasebenzisi uhlala utshintsha, igridi yamandla kufuneka ihlale iqinisekisa ukuveliswa kwamandla kunye nokulinganisela komthwalo. Olona setyenziso lubalulekileyo lwesikhululo sombane oqhutywa ngamanzi kwisixokelelwano samandla kukumodareyitha amaza. Ewe kunjalo, amandla amakhulu amakhulu ombane weMiwonyo eThathu asetyenziswa ikakhulu ukwenza umbane. Xa kuthelekiswa nezinye iintlobo zezikhululo zombane, izikhululo zombane oqhutywa ngamanzi zineengenelo zendalo ekumodareyithweni kwamaza. I-iturbine yamanzi inokukhawuleza ukulungelelanisa isantya, esinokuthi kwakhona silungise ngokukhawuleza imveliso esebenzayo kunye nesebenzayo yejenereyitha, ukuze ulungelelanise ngokukhawuleza umthwalo wegridi, ngelixa amandla okushisa kunye namandla enyukliya ahlengahlengisa imveliso ye-injini ngokucothayo. Logama nje ibhalansi yamandla esebenzayo yegridi yamandla ilungile, umbane uzinzile. Ke ngoko, izikhululo zombane wamanzi zenza igalelo elikhulu kuzinzo rhoqo lwegridi yamandla.
Okwangoku, izikhululo zombane ezincinci kunye neziphakathi e-China ziphantsi ngokuthe ngqo kwigridi yamandla. Igridi yamandla kufuneka ibe nolawulo olupheleleyo kumatshini wamandla wokumodareyitha amaza ombane aphambili, ukuze kuqinisekiswe ukuzinza kwegridi yamandla ombane kunye nombane. Ngokulula:
1. Igridi yamandla imisela isantya semoto. Ngoku sisebenzisa ii-motor ze-synchronous zokuvelisa amandla, oko kukuthi, izinga lokutshintsha lifana nelogridi yamandla, oko kukuthi, amaxesha angama-50 ngomzuzwana omnye. Kwijenereyitha yeplanti yamandla obushushu enepere enye kuphela yee-electrode, ijikeleza iirevolutions ezingama-3000 ngomzuzu. Ijenereyitha yeplanti yombane we-hydropower ene-n pair of electrode, ijikeleza i-3000 / N kwi-1 ngomzuzu. I-iturbine yamanzi kunye nejenereyitha zidityaniswa ngokubanzi ngesixhobo esithile sosasazo olusisigxina, ngoko ke kunokutshiwo ukuba ikwamiselwa ngamaza omoya wegridi yamandla.
2. Yintoni indima yendlela yokulawula amanzi? Lungisa imveliso yejeneretha, oko kukuthi, amandla athunyelwe yijeneretha kwigridi yamandla. Ngokuqhelekileyo, amandla athile afunekayo ukugcina i-generator ifikelele kwisantya sayo esilinganisiweyo, kodwa emva kokuba i-generator ixhunyiwe kwigridi yamandla, isantya sejeneretha sinqunywe yi-frequency grid frequency. Ngeli xesha, sihlala sicinga ukuba i-frequency yegridi yamandla ihlala ingatshintshi. Ngale ndlela, xa amandla ejeneretha edlula amandla afunekayo ukugcina isantya esilinganiselweyo, i-generator ithumela amandla kwigridi kwaye ithatha amandla ngokuchaseneyo. Ke ngoko, xa i-motor ivelisa amandla phantsi komthwalo onzima, yakuba ikhutshiwe kwi-motor, isantya sayo siya kunyuka ngokukhawuleza ukusuka kwisantya esilinganisiweyo ukuya kumaxesha aliqela, aqheleke kwiingozi zokubhabha!
3. Amandla enziwe yijenereyitha aya kuthi ngokulandelayo achaphazele i-frequency yegridi, kwaye iiyunithi zamandla ombane wamanzi zidla ngokusetyenziswa njengeeyunithi zokumodareyitha amaza ngenxa yomlinganiselo ophakamileyo wolawulo.
