Abstract

In this letter, the effects of line compensation of an SMIB power system using FC-TCR type TCSC or SVC for transient stability enhancement are analyzed. In particular, a novel method for analysis of line compensation by an SVC is presented. The maximum power transfer, P_emax for line compensation by FACTS controllers can be written in the form P_emax=P_max/(1-k) where P_max is the maximum power transfer for the uncompensated line and k is the degree of compensation. The analysis revealed that the effectiveness of the SVC for stability enhancement is increased if the degree of compensation of the line is increased
