Due to the consequences, several power quality issues such as harmonic distortion emerged that led to degradation of electrical devices connected at the load end. The main priority of a three phase supply is to operate in a balanced and sinusoidal behavior. A variety of power custom devices have been developed to improve the power quality of the supply such as Unified Power Quality Conditioner, Dynamic Voltage Restorer and Distribution Static Compensator (D-STATCOM). From the literature review, D-STATCOM comprises several benefits where the implementation of the controller is much easier and able to reduce the harmonics instantly. The main aim of this project are to analyze the impact of harmonics in the system and to reduce the total harmonic distortion (THD) of the source current below the IEEE STD 519-2014 standard limit which is 5% for less than 1 kV system. This work is utilizing D-STATCOM device as the main component that requires a specific controller which is Synchronous Reference Frame Theory (SRFT) method to effectively improve the harmonic contents of the source current. This theory is using Park‟s transformation equation to generate the reference current in order to be compared with the actual source current. Two PI controllers are required to maintain the current at point of common coupling and the DC bus voltage to become constant even though the PV irradiation levels are varied. The simulation is done based on three different cases where the outcome of the results is obtained before and after the system is connected to the D-STATCOM device. The simulation is modeled by using MATLAB/Simulink R2019a software while the result of the THD percentage is achieved by using Fast Fourier Transform (FFT) analysis window. The results obtained shows that the total harmonic distortion of supply current has been successfully reduced within its permissible limit. The source current waveform has been improved through its sinusoidal waveform manners after being connected to the D-STATCOM device with THD percentage obtained reduced from 28.56% to 3.53%. Despite having changes in PV irradiation levels, the same results are attained where all THD percentage values falls below limit for all the individual phases. 2023-05-03T16:53:51Z 2023-05-03T16:53:51Z 2020-09 https://irepository.uniten.edu.my/handle/123456789/21438 en application/pdf
