Compensation of Neutral Current, Reactive Power Mitigated by DSTATCOM, using a Unit Vector Control Algorithm

Manish Gurawa | Neeraj Kumar Kumawat

Abstract: The load neutral current will help to carry the electrical power, it provides a path to current from load to source but whenever there is an unbalance condition on the load side it will affect the source system to a large extent. It will affect the whole electrical network and also affect the performance of equipment that we use in the provided system.That is why we need a system that improves this type of problem that occurs accordingly. Several different DSTATCOM topologies can be used for neutral current mitigation and power quality compensation in three-phase, four-wire systems that have a neutral terminal on either the positive or negative dc bus: a 4-legged voltage source converter (VSC), a 3-legged voltage source converter (VSC), To top it all off, the proposed way of boosting the electric supply system's quality by utilising three-phase four-wire distribution is far more efficient than previous approaches. Hence, the compensation of this current will help in increasing the performance of power system equipment. This paper presents the design and implementation of a distribution static compensator (DSTATCOM) with the T connected system. The unit vector template method based control algorithm has been implemented for the control of the proposed DSTATCOM. The proposed test model has been simulated in a SIMULINK/MATLAB environment. The simulations results show the effectiveness of the proposed algorithm.
