Fast response SSSC based on instantaneous power theory

The abilities of SSSC over impedance type make it more preferable in many applications. Fine control schemes and settings should be applied in order to achieve these superior abilities. In addition, the quadrature voltage generated by SSSC with respect to the phase voltage gives its ability to control the load angle and then the power flow of the transmission line. This paper propose control scheme for regulating power flow of the transmission line by using the voltage as a reference. Dynamic response of the SSSC was investigated by the digital simulation. Simulation results illustrate effectiveness of the SSSC under control schemes with use of instantaneous power theory. Furthermore, the SSSC with quadrature voltage control scheme showed its ability to control the power flow of the transmission line.
