Effect of Transformer Rating on the Power Quality Problems in 11kv/440v Distribution System
Authors: , , ,
Abstract: This study explains in detail how the transformer rating affects the proposed distribution system. Also analysis of the suggested distribution system would react when the transformer rating is changed to reduce harmonic interference, this information is essential. The harmonic in the voltage waveform is changed by changing the transformer's rating. The nonlinear and imbalanced load is taken into account in this approach. To reduce harmonics caused by nonlinear and imbalanced loads along with by adjusting the transformer's rating up or down, an SRF-controlled algorithm is suggested. An 11kV/400V distribution system framework, the SRF- controlled DSTATCOM with four-leg VSI is proposed and placed into the system. The proposed DSTATCOM is evaluated for its ability to regulate the voltage at the PCC as the transformer rating rises and falls in nonlinear and imbalanced load conditions. The outcomes of the suggested work are acquired using the MATLAB/SIMULINK program.
