SCT dimensions optimization by harmony search algorithm

In this paper, Controlled Shunt Compensator of Transformer type (CSCT) is introduced as a new shunt compensator and harmonic component of its current is presented. A filter block in tertiary winding of the CSCT is used to suppress these harmonics. It is demonstrated that operation of the filter block is influenced by the arrangement of the windings and their dimensions. Then two possible arrangements of the CSCT windings are considered and the best arrangement and CSCT winding dimensions will be determined using harmony search method.
