CONTROLLER-DESIGN USING, MU-SYNTHESIS FOR STATIC VAR COMPENSATOR ENHANCE THE VOLTAGE PROFILE FOR REMOTE INDUCTION-MOTOR LOADS

This paper deals with the design and implementation of a robust contro ller for the static VAR compensator (SVC) in remote industrial power s ystem, to enhance the voltage profile for three phase single cage indu ction motor (SCIM) loads. The controller design is based on mu-synthes is method to deal with uncertainties arising in industrial network mod eling. The performance of the controller has been evaluated extensivel y by non-linear time domain simulation. It is concluded that the robus t controller enhances the voltage profile for SCIM loads compared with conventional SVC type (CSVC), which consist of voltage and current fe edback loops.
