ANALISIS SISTEM KINERJA ELECTROSTATIC PRECIPITATOR (ESP) DI PLTU PELABUHANRATU

The Pelabuhanratu Steam Power Plant (PLTU) plays a strategic role in electricity supply, but its high coal consumption has the potential to produce high emissions. Electrostatic Precipitators (ESPs) are used to control particulate emissions, and their efficiency is strongly influenced by electrical parameters, namely current and voltage. Problems such as transformer tripping and current and voltage hunting can degrade ESP performance. Therefore, research on current and voltage configurations is necessary to maintain optimal ESP efficiency and ensure emissions meet environmental quality standards. This research focuses on current and voltage configurations to ensure optimal ESP performance at high load levels. Based on the research results, two configurations were obtained at the same load level with different efficiency values. The optimum configuration with an average voltage of 47.68 kV produced an electric field strength of 119.2 kV/m with a particle migration velocity of 0.0405 m/s and an efficiency of 98.65%. The layered configuration with an average voltage of 51.46 kV produced an electric field strength of 168.26 kV/m with a particle migration velocity of 0.0471 m/s and an efficiency of 99.33%. The layered voltage was chosen because it is closer to the design value, distributes the electric field strength more evenly, and allows for stable, continuous operation. This study uses a field trial method based on CEMS data and operational measurements of ESP unit 2 of the Pelabuhanratu PLTU.
