Ukuthembeka kokunikezwa kwamandla kungenye yeziqinisekiso ezibalulekile zokusebenza okuvamile komphakathi wanamuhla. Ekukhiqizweni kwamandla, amasethi ejeneretha, njengemishini ebalulekile, adlala indima ebalulekile.
Injini esebenza kahle kakhulu yokonga amandlaamasethi ejeneretha awuhlobo lwemishini yokuphehla amandla ekhiqizwa ngobuchwepheshe obuthuthukisiwe nezinto zokwakha. Izinzuzo zayo zibonakala ngokuyinhloko kulezi zici ezilandelayo:
- Amasethi ejeneretha enjini asebenza kahle kakhulu anamandla aphezulu. Isethi yejeneretha isebenzisa ubuchwepheshe bezimoto obuthuthukisiwe ukuze kuthuthukiswe ukusebenza kahle kokuguqulwa kwamandla, ngaleyo ndlela kunciphise ukumosheka kwamandla. Uma kuqhathaniswa namasethi endabuko akhiqiza ugesi, ingahlangabezana kangcono nesidingo samandla, inciphise ukuncika ezinsizeni zikaphethiloli, futhi inciphise ukungcoliswa kwemvelo.
- Amasethi ejeneretha enjini esebenza kahle kakhulu anempilo ende yesevisi. Ngokusebenzisa izingxenye zekhwalithi ephezulu kanye nezinqubo zokukhiqiza ezithuthukisiwe, ukwethembeka kwesethi ye-generator kuye kwathuthukiswa kakhulu. Lokhu kusho ukuthi ingaqhubeka nokusebenza isikhathi eside, inciphisa imvamisa yokulungisa nokushintshwa, futhi yehlise nezindleko zokuyilungisa.
- Amasethi ejeneretha enjini eyonga amandla aphezulu anomsindo ophansi kanye namazinga okudlidliza. Umsindo nokudlidliza okukhiqizwa isethi yejeneretha ngesikhathi sokusebenza kuyizinkinga ezivamile, ezingase zibe nomthelela omubi endaweni ezungezile kanye nempilo yomuntu. Isethi yejeneretha yokonga amandla ephezulu isebenzisa ubuchwepheshe bokunciphisa umsindo kanye nomklamo olungiselelwe ukuze ulawule ngempumelelo umsindo nokudlidliza futhi unikeze indawo yokusebenza engcono.
Kodwa-ke, kunemikhawulo ethile yokusebenza kahle kakhulu kanye namasethi ejeneretha enjini yokonga amandla.
- Inani layo liphezulu uma kuqhathaniswa. Ngenxa yokusetshenziswa kobuchwepheshe obuthuthukisiwe nezinto zokwakha, kanye nokuhlinzeka ngemisebenzi eyengeziwe nokusebenza, izindleko zokukhiqiza zamasethi ejeneretha enjini asebenza kahle kakhulu nokonga amandla ziphezulu uma kuqhathaniswa. Lokhu kuholela enanini eliphezulu lokuthengisa kunesethi yamajeneretha endabuko, okukhawulela ukukhetha kwabanye abasebenzisi.
- Amasethi ejeneretha enjini asebenza kahle kakhulu nokonga amandla asenezinselelo ezithile ekusetshenzisweni kwenani elikhulu. Njengamanje, ukukhishwa kwamasethi ejeneretha enjini asebenza kahle kakhulu nokonga amandla kuncane, okungakwazi ukuhlangabezana nezidingo zokunikezwa kwamandla amakhulu. Ngakho-ke, kwezinye izinkambu ezikhethekile noma izikhathi lapho kudingeka khona ugesi wamandla amakhulu, ezinye izindlela zidinga ukutholakala.
Kafushane, injini esebenza kahle kakhulu neyonga amandla(isigaba sesithathu se-asynchronous ac motor) amasethi ejeneretha anezinzuzo ezibalulekile ekuthuthukiseni ukwethembeka kokunikezwa kwamandla. Ukusebenza kahle kwayo kwamandla aphezulu, impilo ende nomsindo ophansi nokudlidliza kuyenza ibe ukukhetha okuhle kwemishini yokuphehla amandla. Kodwa-ke, amanani entengo aphezulu kanye nemikhawulo yamandla okukhiqiza yizici ezikhawulelayo okufanele zicatshangelwe. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwandiswa kwamandla okukhiqiza, kukholakala ukuthi amasethi ejeneretha enjini asebenza kahle kakhulu nokonga amandla azodlala indima enkulu embonini yamandla futhi enze umnikelo omkhulu ekuthuthukiseni ukwethembeka kokuphakelwa kukagesi.SIMO isithuthuthuizobamba leli su ukuze lisebenze ngempumelelo kanye nekhwalithi ephezulu.
