Isidingo esikhulayo samandla kagesi ukuze kuthuthukiswe intuthuko yomhlaba wonke sidinga ukutshalwa kwezimali okuqinile okungaguquki ekuphehleni ugesi.Kodwa-ke, ngaphezu kokuhlela okuyinkimbinkimbi kwesikhathi esimaphakathi neside, lokhu kutshalwa kwezimali kuncike emithonjeni yemvelo, okuyiyo
ukuncipha ngenxa yengcindezi eqhubekayo endaweni ezungezile.Ngakho-ke, isu elingcono kakhulu lokugcina amandla kagesi esikhathini esifushane ukugwema ukumoshakala nokwandisa ukusebenza kahle kwamandla.Izinjini zikagesi zidlala indima enkulu kulelisu;kusukela cishe ku-40%
kwesidingo samandla omhlaba kulinganiselwa ukuthi sihlobene nezicelo zezimoto zikagesi.
Ngenxa yalesi sidingo sokunciphisa ukusetshenziswa kwamandla kanye nokukhishwa kwe-carbon dioxide, Ohulumeni abaningi emhlabeni wonke baye babeka iMithetho yendawo, eyaziwa nangokuthi i-MEPS (Minimum Energy Performance Standards) ezinhlotsheni eziningi zemishini,
kuhlanganise nezinjini zikagesi.
Nakuba izidingo ezithile zale MEPS zihluka kancane phakathi kwamazwe, ukuqaliswa kwamazinga esifunda afana ne-ABNT,I-IEC,I-MG-1, echaza amazinga okusebenza kahle nezindlela zokuhlola ukuze kutholwe lokhu kusebenza kahle, ivumela ukumiswa kwencazelo, ukulinganisa nefomethi yokushicilelwa kwedatha esebenza kahle phakathi kwabakhiqizi bezimoto, okwenza kube lula ukukhetha okufanele kwezinjini.
ukusebenza kahle kwamandla kwamamotho ezigaba ezintathu angewona amabhuleki, i-Ex eb anda amamotho zokuphepha, noma ezinye
amamotho avikelekile ekuqhumeni, anesilinganiso esilinganiselwe esilingana noma ngaphezulu kuka-75 kW futhi alingana noma ngaphansi kuka-200 kW,
2, 4, noma 6 izigxobo, kufanele zihambisane okungenaniIE4izinga lokusebenza kahle elibekwe kuThebula 3.
Ukuze kutholwe ukusebenza kahle okuphansi kwamamotho angama-50 Hz anamandla alinganiselwe e-PN aphakathi kuka-0,12 no-200 kW anganikezwanga kuThebula 1, 2 kanye no-3, le fomula elandelayo izosetshenziswa:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
A, B, C kanye no-D ama-coefficients e-interpolation azonqunywa ngokuya kweThebula 4 no-5.
