Damping of SSR Using Subsynchronous Current Suppressor With SSSC
Abstract—Hybrid series compensation using static synchronous
series compensator (SSSC) and passive series capacitor can improve
the stability of the system, increases the power transfer
capability and is useful for the fast control of power flow. This
paper analyzes the subsynchronous resonance (SSR) characteristics
of the hybrid series compensated power system in detail
and proposes a simple method for the extraction of subsynchronous
components of line current using filter. The extracted
subsynchronous frequency component of line current is used to
inject a proportional subsynchronous voltage in series with the
transmission line which suppresses subsynchronous current in
the transmission network. This novel technique is termed as subsynchronous
current suppressor. The design of subsynchronous
current suppressor is based on damping torque analysis and using
genetic algorithm. A novel graphical representation of series
resonance condition when SSSC is incorporated in the system
is presented. The detailed study of SSR is carried out based on
eigenvalue analysis, transient simulation and damping torque
analysis. The results of the case study on a system adapted from
IEEE First Benchmark Model demonstrates the effectiveness and
robust performance of subsynchronous current suppressor in
damping of SSR under various system operating conditions.
Linear analysis is performed on D-Q model of the system with
SSSC and the results are tested by executing transient simulation
based on detailed nonlinear three-phase model..
