Abstract :
Gas engine power plant is one type of power plant that uses two fuels or better known as dual fuel, where the fuel is natural gas and diesel oil. One of the gas engine power plants in Southeast Sulawesi is the PLTMG Baubau 30 MW. PLTMG Baubau 30 MW has four generators, each generator has an installed capacity of 9780 kW, the contribution of PLTMG Baubau in the electricity system of Baubau City reaches 65% per day. the efficiency of electric power supplied by a generator can be influenced by several factors such as the temperature rise on the stator side of the synchronous generator, when operating a generator it will certainly result in a temperature increase, the temperature increase is caused by the current flowing in the stator copper conductor during the loading process. , the ease between the rotor and the air. generation of heat or excessive temperature rise on the generator side will result in damage to the insulation and shorten the life of the generator. To overcome this problem, the winding temperature and also the engine room temperature need to be limited so that it can suppress the temperature rise that occurs in the generator. Basically, the increase in temperature on the side of the stator winding will cause several losses, namely: copper losses, mechanical losses, stray losses and iron core losses. The losses on the generator side will affect the value of the output power efficiency, therefore it is necessary to analyze the generator efficiency value whether the generator can work optimally or less than optimally. By applying quantitative methods, this research can determine the correlation between several variables which then analyze the results, the data collection process from April 1, 2021 to April 20, 2021, the average efficiency of the 3-phase synchronous generator unit Baubau PLTMG 30 MW is 98.28% with the average total losses on the side of the synchronous generator, which is 107,743 kW, this shows that the generator is still in an optimal state and has the power to generate electricity.
