Development of Electricity Generating System for a Micropower Plant

The move from fossil fuel to clean energy has become the focus of the 21 st century, to suplement the energy needs of the world which have been on the increase.This research tackles the challenge of energy inadequacy by designing and fabricating electric generator for micro-power plant using locally sourced materials.The design of the 5.5kW induction generator involved the application of recycling technique on the discarded scrap motor.Discarded electric motor after cleaning was redesigned and rewound to give an electric power output of 5.5 kW.The generator was tested under load and no load conditions.The outcomes showed that the generator can adequately carry a load of 2.3 kW when operated at speed ranging between 2300 and 2400 pm.The output voltage ranging between 150 V and 190 V, while the ouput current was in the range 6.07A and 6.35A.Higher load carrying capacity, 5.0 kW was achievable at the rotory design speed, 3000 rpm with the maximum voltage and current limits, 239.6 V and 10.467 A, respectively.The 3-phase induction generator was able to sustain higher power output, 5.0 kW of the design capacity.Key words: Electric generator, Micropower plant, Clean energy, Recycling, Palm Kernel Shell (PKS) Razvoj sistema za proizvodnju električne energije kod mikro-elektrana.Prelazak sa fosilnih goriva na čistu energiju postao je u fokusu 21. veka, kako bi dopunili energetske potrebe sveta koji su u porastu.Ovo istraživanje se bavi izazovom neadekvatne energije projektovanjem i proizvodnjom električnog generatora za mikroelektranu koristeći lokalno nabavljene materijale.Dizajn generatora indukcije 5.5kV uključivao je primenu tehnike reciklaže na odbačenom motornom otpadu.Otpadni elektromotor nakon čišćenja je redizajniran i preusmeren da daje električnu snagu od 5,5 kV.Generator je testiran pod opterećenjem i bez opterećenja.Ishodi su pokazali da generator može adekvatno nositi opterećenje od 2,3 kV kada se koristi na brzini od 2300 do 2400 obrtaja u minuti.Izlazni napon se kreće između 150 V i 190 V, dok je struja napona bila u opsegu 6.07A i 6.35A.Veća nosivost nosivosti, 5,0 kV je postignuta na rotacionoj brzini dizajna, 3000 obrtaja u minuti sa maksimalnim naponskim i strujnim granicama, 239,6 V i 10,467 A, respektivno.Trofazni indukcioni generator je mogao održavati veću izlaznu snagu, 5,0 kV od projektovanog kapaciteta.
