Clonal Selection Algorithm to Reduce Parallel Resonance Effect in Electrical Networks

Parallel resonance is significant problem in the electric networks. During parallel resonance, system impedance increase extremely. Therefore system voltage may be increase extremely. Due to the parallel resonance occurs between system impedance and capacitors of reactive power compensation, total capacitor power should be less than the parallel resonance power. In this study, parallel resonance point and power of transformer of the electric network, which was measured harmonic distortion, were determined by using search mechanism of CSA. Thus parallel resonance power of low voltage electric network can be calculated and maximum capacitor of compensation system can be determined. Coefficient of cloning in CSA was increased to obtain high affinity valuable results. But, in this case, the elapsed time increased. Increasing value of the elapsed time is undesirable case. To decrease value of the elapsed time, some changes in CSA were made to obtain high affinity value at short computational time. © 2012 IEEE.
