Enhancement of transmission capability of long transmission line by Fuzzy controlled SVC

ABSTRACT As the technology is advancing, day by day demand of electricity is increasing and hence the consumption is also increasing. Due to restrictions on extension of transmission lines it is necessary to enhance transmission capabilities of existing lines to meet the demand. Among various means of enhancement, reactive power compensation is effective one. In the paper a simulated system is applied with a fuzzy controlled SVC, at one of the buses to study the effects on the voltage and power at buses. Analysis shows that there is considerable increase in the voltage and power at that bus which helps to improve the transmission capability of the system.
