Mitigation of Neutral Current in a Three Phase System using Electric Springs
Three-Phase four-wire distribution systems are widely used for distributing power to many residential and commercial buildings. The increased use of non-linear and unbalanced loads in these systems may result in excessive neutral currents. This may damage the neutral conductor and distribution transformer while affecting the safety of the consumers and also causes several other power quality problems in the system. The proposed strategy employs a new three phase electric spring circuit for reducing neutral current in the system. MATLAB/SIMULINK platform is used for simulation. The application of the proposed method has been investigated for different load conditions and the results are presented.
