Analisis Perubahan Beban Terhadap Efisiensi Generator Avk Type DIG142 PLTMG Maxpower Panaran

Abstract

The demand for electrical energy sources is increasing, but in propotion to the increasing number of energy sources, therefore efficiency is needed so that the electrical energy produced from a generator can be maximized. One of the electrical energy generators in Batam is the gas engine power plant (PLTMG). Maxpower Panaran. PLTMG Maxpower Panaran has 18 synchronous generator units, Panaran 1 unit with an output power of 25 MW and Panaran 2 unit with an output power of 25 MW. PLTMG Maxpower Panaran uses the LEANOX Control method, where the engine is supplied by a gas mixture with surplus air which then enters the combustion chamber, the result of the combustion process pushing the piston in the engine cylinder. This piston movement produces mechanical energy. The gas engine shaft is coupled to the generator shaft so that the output power from the gas engine is the input power to the generator. To determine the performance of the synchronous generator at PLTMG, it is necessary to know the efficiency of the generator. From the results of the analysis carried out, it was obtained that the efficiency of the synchronous generator based on specification data in unit 7 was 97,93 % and in unit 3 it was 97,66 % and based on log sheet data it was obtained that the average efficiency of the synchronous generator in unit 7 was 90,35 % and unit 3 of 87,43 %
