Analysis of SSR with SSSC using FPA based Voltage Controller

This paper presents, the SSR characteristic analysis of the system with combined active and passive series compensation methods to increase secure loading, stability and fast control of power in the transmission line. The hybrid compensation is done by considering SSSC (an active FACTS device) and fixed series capacitor (passive compensation) method. Also, the Flower Pollination Algorithm is adopted in designing of the SSSC with Type-1 controller based on the damping torque analysis. The SSR analysis is carried out using damping torque, eigenvalue and transient simulation methods which show the effectiveness of SSSC in the elimination of torsional interaction at the operating point. The SSSC with Type-1 controller shows better performance in reducing the network resonant frequency along with improved power transfer capability of line.
