Abstract


This paper investigates the steady state performance of long line with reactive compensation provided through transformer tap control on one side and shunt compensation provided on the other side. Constant voltage contours in the parametric plane are obtained. Also the voltage profile over the line together with the flatness index is determined. Results of case studies are presented and analyzed. This study can make a foundation to build up an expert system through which the voltage at the load end can be controlled by suitably designed parameters of both the compensators.
