Abstract: In contrast with the past the electrical Power quality (PQ) has become the main matter of interest for both utilities and consumers because the loads on the consumer side get affected and also may get damaged. Now, electricity customers are in a separate position to claim a higher quality of service. Efficient power quality (PQ) of control and analysis systems can help to accomplish this goal. This work displays a Zigzag-Delta transformer -based technique for the disclosure of operational events and power quality disturbances concurred with these events. . The power factor advancement by reactive power, neutral current compensation and load balancing in a three-phase four-wire system are yielded by the proposed DSTATCOM (Distribution Static Compensator). The power factor correction mode of operation of the DSTATCOM have been recognized as expected ones. The dc bus voltage of the DSTATCOM has been monitored with respect to the reference dc bus voltage under all uncertain loads. The thorough simulation study of power quality disturbances has been carried out in MATLAB/Simulink environment.
