| Summary: | An electrical power system consists of generators, transmission and the distribution network. These networks will deliver power to varying the linear and non-linear loads for consumers. Usually nonlinear electrical devices cause the harmonics distortion of the output sine waveforms of source voltages and currents. Besides, the penetration of Photovoltaic (PV) into distribution increases the harmonics distortion. The equipment of electronic devices will overheat and cause malfunction if it is connected to electrical power system. Removing the harmonic pollution is crucial but it is not an easy task. Therefore, the purpose of this project is to mitigate the harmonic which is generated by Photovoltaic (PV) and nonlinear load using Shunt Active Power Filter (SAPF). This project is designed and simulated by using MATLAB Simulink software as a simulation tool. The analysis of harmonics are carried out using Fast Fourier Transform (FFT) to evaluate the Total Harmonic Distortion (THD) of the nonlinear load and Photovoltaic (PV) with filter and without filter. The results shows that the harmonic distortion is reduced by using the proposed filtering method. |
