Abstract

One of the factors that affect the performance of photovoltaic cells is shading. Shading can reduce the intensity of solar radiation on the cells. This study aims to design a system that can improve the amount of voltage from shading disturbances to optimise the output voltage on the solar cell by using a reflector. The reflector is designed in a flat mirror measuring. It is expected that there will be an increase in the output voltage of the existing solar cell system. The more reflected light that hits the surface of the solar panel and illuminates the shading area, the more significant the increase in output voltage, current and power, and vice versa.

Abstract

Electrical distribution is one of the most important parameters in industrial processes. Therefore, good power quality is needed as a supply to industrial machines. The use of industrial machines has an impact on the emergence of harmonics. As a result of the large Harmonics, the quality of power is getting worse, affecting productivity in the industry. Therefore, samples were taken using a Power Quality Analyzer on an 800 kVA transformer on the secondary side of the transformer to maximise the supply of electricity to consumers. Then obtained THDi Phase L1 of 23.1%, phase L2 of 24.7% and phase L3 of 21% and IHDi on the 5th order in phase L1 18.3%, phase L2 20.7% and phase L3 16.6% regarding (IEEE Std 3002.8-2018) and (SPLN D5.004-1:2012) the IHDi value should not be more than 7%. Then simulated using MATLAB/Simulink by designing the Second Order High Pass Filter and C-Type Filter. The results obtained by combining the two filters gained THDi results in the L1 phase at 2.53%, the L2 phase at 2.69% and the L3 phase at 2.22% and the IHDi at the 5th order of the L1 phase at 1.48%, the L2 phase 1.62% and L3 phase 1.33%.
