Planning, Design and Installation of a Hybrid Power Filter to Power Quality Improvement for Grid-Connected Renewable Energy Systems

This paper is a preliminary basis in the design, planning, and implementation of hybrid power filter systems (HPFs) for application in grid-connected solar rooftop at industrial plants beginning the planning and designing of a 260 kWp solar rooftop according to the factory roof size. Calculate total returns by using the PV system design software program to find the total kWh received per year. As the power system in this factory has a load that is sensitive to power quality and harmonics, it is necessary to design a harmonic protection system by choosing the HPFs to reduced and control the harmonics. Noise filters should be used to prevent high-frequency signals from entering the electrical system. In addition, lightning protection devices are also designed by using the bus bar to connect the system to the ground. All actions have been carried out in accordance with the designed plan and able to perform as intended.
