Abstract

Pelabuhan Ratu Steam Power Plant is located at Jalan Raya Cipatuguran Desa Jayanti, Citarik, Kecamatan Pelabuhanratu, Kabupaten Sukabumi, West Java, Indonesia, with a total capacity of approximately 3 X 350 megawatts (MW). Generators, especially those used in large power plants, require cooling as they produce heat as a by-product of energy conversion. The coolant used in the generators at Pelabuhan Ratu Steam Power Plant is water and hydrogen. Hydrogen is used as a cooling medium because it has good thermal properties and high thermal conductivity, so it can absorb heat efficiently. It is important to note that the use of hydrogen coolant in brushless generators requires appropriate processing and security systems to avoid the risk of hydrogen leakage which can cause fire or explosion hazards. It is also necessary to maintain the purity of hydrogen gas in the cooling system. The problem that occurs in the Pelabuhan Ratu Steam Power Plant is that the purity of hydrogen in the generator cooling system cannot be maximized. The methods used include comparative statistical analysis to compare the performance of hydrogen cooling generators with and without hydrogen drying equipment, to determine if there is a significant difference, or regression analysis to identify factors that affect generator temperature. This study aims to maintain the purity of hydrogen can last longer by using a hydrogen dryer and analyze the effect of hydrogen purity is maintained on the power output of the generator. The results obtained hydrogen dryer system is able to maximize the purity of hydrogen from 96.7% to 98.6%. Hydrogen temperature readings of the cold exciter and hot exciter generator side become lower from 37.5 ℃ and 47.9 ℃ with 328.0MW power to 33.3 ℃ and 46.6 ℃ with 332.1MW power. And the cold turbine and hot turbine side hydrogen generator temperature readings also decreased from 36.6 ℃ and 49.1 ℃ with 328.0MW power to 31.6 ℃ and 47.1 ℃ with 332.1MW power. Analytical research can provide a solid basis for better decision-making. By analyzing relevant data and information, researchers can identify problems or opportunities, evaluate options, and provide recommendations based on the evidence and findings found. This helps decision makers at Pelabuhan Ratu Steam Power Plant make more informed and fact-based decisions.
