This paper presents an adaptive short-time compensation scheme for improving power system stability. The proposed compensation is based on the use of Static Synchronous Series Compensator (SSSC), which provides the needed phase-wise compensation resulted from selective-pole switching of parallel transmission lines. The transmission system is balanced during the dead-time; time lapsed from fault clearing to highspeed reclosing (HSR). The validity and effectiveness of the proposed compensation scheme in enhancing power system stability are demonstrated through time-domain simulation studies on a multi-machine power system using the EMTP-RV program.
