Fuelless Power Generating Set and Power Inverter System: Analysis of Load and Efficiency Appraisal

Abstract

There is need for engineers to search for alternative power source as it is important due to need for a cleaner source of power that is environmental friendly. Fuelless power generator as fuelless generation is a device that is understood to function without the need for internal combustion engine which usually request for fuel as a source of input while power inverter or an inverter is an electrical power converter that changes direct current (D.C) to alternating current (A.C). Both inverter and fuelless power generating set was designed and constructed at Federal College of Agriculture, Moor Plantation Ibadan, Nigeria by the author. This research will focus on comparison of the two devices in terms of there load performance. The performance evaluation of the machine revealed that when there is no load acting on the machine, the efficiency of the machine is said to be at 0%. It can be concluded that the machine had the highest efficiency of 97.40% at a load of 100W and the lowest efficiency of 71.70% at a load of 600W. It was also observed that there is a decrease in the output of the machine when there is a high increase in the load. The result of the performance evaluation of the fuel-less power generating set shows that the machine is said to have an average efficiency of 56.43% at load of 600W for continuous operation. The peak efficiency of the constructed fuel-less power generating set will be 89.1% at load of 100W. For comparison, the result obtained from Power inverter, has clearly confirmed that the highest efficiency recorded is at 96.27% which is more higher than that of the fuel-less power generating set which is at 89.1%, at a load of 100W respectively.
