Imvamisa ye-AC ayihlobene ngqo nesivinini senjini sesiteshi sikagesi wamanzi, kodwa ihlobene ngokungaqondile.
Kungakhathaliseki ukuthi hlobo luni lwemishini yokukhiqiza ugesi, idinga ukudlulisa ugesi kugridi yamandla ngemva kokukhiqiza ugesi, okungukuthi, ijeneretha idinga ukuxhumeka kugridi ukuze ikhiqize ugesi. Ngemva kokuxhumeka kugridi, ixhunywe kugridi yamandla iyonke, futhi amaza kuyo yonke indawo kugridi yamandla afana ncamashi. Uma igridi yamandla inkulu, ibanga lokuguquguquka kwemvamisa lincane futhi imvamisa izinze kakhulu. Kodwa-ke, imvamisa yegridi yamandla ihlobene kuphela nokuthi ugesi osebenzayo ulinganisiwe yini. Lapho ugesi osebenzayo okhiqizwa yisethi yejeneretha umkhulu kunamandla asebenzayo kagesi, imvamisa iyonke yegridi yamandla izokhula, futhi okuphambene nalokho.
Ibhalansi yamandla asebenzayo iyinkinga enkulu yegridi yamandla. Ngenxa yokuthi umthwalo wamandla wabasebenzisi uhlala ushintsha, igridi yamandla kufanele iqinisekise njalo ukuthi umkhiqizo wokukhiqiza amandla kanye nebhalansi yomthwalo uyaphuma. Inhloso ebalulekile yesiteshi samandla kagesi ohlelweni lwamandla ukushintshashintsha kwemvamisa. Vele, amandla amakhulu kakhulu e-hydropower e-Three Gorges asetshenziselwa kakhulu ukukhiqiza amandla. Uma kuqhathaniswa nezinye izinhlobo zeziteshi zamandla, iziteshi zamandla kagesi zinezinzuzo ezingokwemvelo ekushintsheni kwemvamisa. I-turbine yamanzi ingalungisa ngokushesha isivinini, okungalungisa futhi ngokushesha umkhiqizo osebenzayo nosabelayo wejeneretha, ukuze kulinganiswe ngokushesha umthwalo wegridi, kuyilapho amandla okushisa kanye namandla enuzi kulungisa umkhiqizo wenjini kancane kakhulu. Uma nje ibhalansi yamandla asebenzayo yegridi yamandla ilungile, i-voltage izinzile. Ngakho-ke, iziteshi zamandla kagesi zinegalelo elikhulu ekuzinzeni kwemvamisa yegridi yamandla.
Njengamanje, iziteshi eziningi zamandla kagesi ezincane neziphakathi eShayina zingaphansi kwegridi yamandla ngqo. Igridi yamandla kumele ibe nokulawula * * * phezu kwezitshalo zamandla eziyinhloko zokuguqula imvamisa, ukuze kuqinisekiswe ukuzinza kwemvamisa yegridi yamandla kanye ne-voltage. Kalula nje:
1. Igridi yamandla inquma ijubane lenjini. Manje sisebenzisa ama-motor ahambisanayo ukuze kukhiqizwe amandla, okungukuthi, izinga lokushintsha lifana nelegridi yamandla, okungukuthi, izikhathi ezingama-50 ngomzuzwana owodwa. Kujeneretha wesitshalo samandla esishisayo one-electrode eyodwa kuphela, ujikeleza ama-revolution angu-3000 ngomzuzu. Kujeneretha wesitshalo samandla e-hydropower enama-electrode angu-n, ujikeleza ama-electrode angu-3000 / N ngomzuzu owodwa. I-turbine yamanzi kanye nejeneretha ngokuvamile kuxhunywe ndawonye ngendlela ethile yokudlulisa isilinganiso esinqunyiwe, ngakho-ke kungashiwo ukuthi kunqunywa futhi imvamisa yegridi yamandla.
2. Iyini indima yendlela yokulawula amanzi? Lungisa ukuphuma kwejeneretha, okungukuthi, amandla athunyelwa yijeneretha kugridi yamandla. Ngokuvamile, kudingeka amandla athile ukuze ijeneretha igcine ijubane layo elilinganiselwe, kodwa uma ijeneretha isixhunywe kugridi yamandla, ijubane lejeneretha linqunywa imvamisa yegridi yamandla. Ngalesi sikhathi, sivame ukucabanga ukuthi imvamisa yegridi yamandla ihlala ingashintshi. Ngale ndlela, uma amandla ejeneretha edlula amandla adingekayo ukuze kugcinwe ijubane elilinganiselwe, ijeneretha ithumela amandla kugridi futhi imunce amandla ngokuphambene nalokho. Ngakho-ke, lapho injini ikhiqiza amandla ngaphansi komthwalo osindayo, uma isinqamukile kumoto, ijubane layo lizokhula ngokushesha lisuka ejubaneni elilinganiselwe liye ezikhathini eziningana, okuvame ukubangela izingozi zokundiza!
3. Amandla akhiqizwa yijeneretha azothinta imvamisa yegridi, futhi amayunithi kagesi wamanzi avame ukusetshenziswa njengamayunithi okuguqula imvamisa ngenxa yesilinganiso sokulawula esiphezulu.
