【 摘 要 】

Generator set is a tool that is used to generate energy or electrical power. The electric power generated by the generator set is used to supply the electrical loads in this thesis is lamp. Power that can be produced by a generator set is ranged between 100-1200 watt. The power generated by generator set is used influenced by a mixture ofair and fuel. Generator set used is dual fuel generator set. From the results of this study, a stable response with overshoot value below 0% and its error is 2%. In addition, the best obtained value of Air Fuel Ratio (AFR) is 15.06, Furthermore, the stability of the power generated by the generator set is also influenced by the flowrate mass of the fuel injected into the combustion chamber. From the simulation results when given a power set point at 1200 watt, obtained value of the air mass flowrate is 0.03754 kg/s, mass flowrate of biogas is 0.002367 kg/s, and gasoline constant mass flowrate is 0.000125 kg/s. Meanwhile, when given a set point of 100 watts of power, a value of 0.009928 kg/s air mass flowrate is injected to the chamber, mass flowrate of biogas is 0.0005341 kg/s and the mass flowrate of gasoline is 0.000125 kg/s. The goal of output power control on generator set is to make generator working to produce output power in accordance to required load.
