I-AC frequency ayinxulumananga ngokuthe ngqo nesantya senjini yesikhululo samandla ombane, kodwa inxulumene ngokungathanga ngqo.
Nokuba loluphi uhlobo lwezixhobo zokuvelisa umbane, kuyimfuneko ukudlulisa amandla ombane kwigridi yamandla emva kokuvelisa amandla ombane, oko kukuthi, ijenereyitha kufuneka iqhagamshelwe kwigridi ukuze ivelise umbane. Emva kokuqhagamshelwa kwigridi, iqhagamshelwe kwigridi yamandla iyonke, kwaye iifrikhwensi kuyo yonke indawo kwigridi yamandla ziyafana. Okukhona igridi yamandla inkulu, kokukhona uluhlu lokuguquguquka kwamaza luncinci kwaye kokukhona ifrikhwensi izinze ngakumbi. Nangona kunjalo, ifrikhwensi yegridi yamandla inxulumene kuphela nokuba amandla asebenzayo alinganisiwe na. Xa amandla asebenzayo akhutshwa yiseti yejenereyitha engaphezulu kwamandla asebenzayo okusetyenziswa kombane, ifrikhwensi iyonke yegridi yamandla iya kunyuka, kwaye ngokuchaseneyo.
Ibhalansi yamandla asebenzayo yingongoma ephambili kwigridi yamandla. Ngenxa yokuba umthwalo wamandla wabasebenzisi uhlala utshintsha, igridi yamandla kufuneka ihlale iqinisekisa imveliso yokuvelisa umbane kunye nebhalansi yomthwalo. Injongo ebalulekileyo yesitishi samandla e-hydropower kwinkqubo yamandla kukuguqulwa kwamaza. Kakade ke, amandla amakhulu e-hydropower e-Three Gorges asetyenziselwa kakhulu ukuvelisa umbane. Xa kuthelekiswa nezinye iintlobo zezikhululo zamandla, izikhululo zamandla e-hydropower zinezibonelelo ezisisiseko ekuguqulweni kwamaza. I-turbine yamanzi inokulungisa ngokukhawuleza isantya, nto leyo enokulungisa ngokukhawuleza imveliso esebenzayo nesabelayo yejenereyitha, ukuze ilungelelanise ngokukhawuleza umthwalo wegridi, ngelixa amandla obushushu kunye namandla enyukliya elungisa imveliso yenjini kancinci kakhulu. Lo gama nje ibhalansi yamandla esebenzayo yegridi yamandla ilungile, i-voltage izinzile. Ke ngoko, izikhululo zamandla e-hydropower zinegalelo elikhulu kuzinzo lwamaza egridi yamandla.
Okwangoku, izitishi ezininzi zamandla ombane ezincinci neziphakathi eTshayina ziphantsi ngqo kwegridi yamandla. Igridi yamandla kufuneka ibe nolawulo kwizikhululo zamandla zokuguqula ifrequency eziphambili, ukuze kuqinisekiswe uzinzo lwefrikhwensi yegridi yamandla kunye nevolthi. Ngamafutshane:
1. Igridi yamandla imisela isantya semoto. Ngoku sisebenzisa iimoto ezihambelanayo ukuvelisa umbane, oko kukuthi, izinga lokutshintsha lifana nelegridi yamandla, oko kukuthi, amaxesha angama-50 ngomzuzwana omnye. Kwijenereyitha yesityalo samandla esishushu esinee-electrode ezimbini kuphela, ijikeleza ii-3000 ngomzuzu. Kwijenereyitha yesityalo samandla e-hydropower esinee-electrode ezimbini, ijikeleza ii-3000 / N ngomzuzu. I-turbine yamanzi kunye nejenereyitha zihlala zidibene ngokusebenzisa indlela ethile yokudlulisela umlinganiselo osisigxina, ngoko ke kunokuthiwa ikwamiselwa yi-frequency yegridi yamandla.
2. Idlala yiphi indima indlela yokulawula amanzi? Lungisa imveliso yejenereyitha, oko kukuthi, amandla athunyelwa yijenereyitha kwigridi yamandla. Ngokwesiqhelo, kufuneka amandla athile ukuze ijenereyitha ifikelele kwisantya sayo esilinganiselweyo, kodwa xa ijenereyitha iqhagamshelwe kwigridi, isantya sejenereyitha simiselwa yifrikhwensi yegridi. Ngeli xesha, sihlala sicinga ukuba ifrikhwensi yegridi ayitshintshi. Ngale ndlela, xa amandla ejenereyitha edlula amandla afunekayo ukugcina isantya esilinganiselweyo, ijenereyitha ithumela amandla kwigridi kwaye ifunxe amandla ngokuchaseneyo. Ke ngoko, xa imoto ivelisa amandla phantsi komthwalo onzima, xa isusiwe kwi-, isantya sayo siya kwanda ngokukhawuleza ukusuka kwisantya esilinganiselweyo ukuya kumaxesha amaninzi, nto leyo enokubangela iingozi zokubhabha!
3. Amandla aveliswa yijenereyitha aya kuchaphazela i-grid frequency, kwaye iiyunithi zamandla e-hydropower zihlala zisetyenziswa njengeeyunithi zokuguqula i-frequency ngenxa yesantya esiphezulu solawulo.
