Abstract

The output of electricity for power plants and output of steam for industrialfurnaces related with flue gas concentration, such as fly ash (dust), CO, CO2NOx, and SO2. The condition of flue gas product is very important for estimatedthe actual level of emissions, because it product depends on type of plant,operating conditions, maintenance, and on fuel properties. The consequence ofcoal combustion, a considerable increase in emissions of dust, hydrocarbon,NOx and SO2 is to be expected. Therefore, to use the abatement technology,such as filters, desulphurization plants, de-nitrification unit, fluidized bedcombustion, and integrated gas combined cycle power plants for reducing theconcentrations of flue gas is an appropriate choice.Kata kunci: coal combustion, flue gas, emission

Abstract

Power quality is a critical aspect of the effective and dependable operation of electrical systems. In today's technologically advanced world, where industries rely significantly on electricity, understanding and maintaining power quality is critical. National Research and Innovation Agency (BRIN) has an important laboratory for aerodynamic testing technology service activities in Indonesia. This facility contains a closed wind tunnel, a DC drive system, and a DC electric motor. This innovative fan drive system employs a parallel DC drive system, with the master and slave motors connected to a master DC drive system and a slave DC drive system, respectively. The usage of a new system results in poor electrical power quality, with a power factor value of less than 0.85, resulting in higher electricity costs and increased current, which has an impact on other equipment, such as a rise in temperature. To improve the quality of electrical power according to standard operating procedures and lower electricity bills, the current work evaluated the new system using field tests and literature studies on the impact of installing capacitor banks in parallel DC motor systems to boost the power factor value. This evaluation aims to improve the quality of the ILST parallel electric power system by including a capacitor bank in each motor.
