Application of Static Synchronous Series C1ompensator to wind farms

This research studies the application of static synchronous series compensator (SSSC) to fixed speed wind farms. Wind farms are located far away from the grid and the power has to be transmitted over long transmission line. Long transmission lines limit the amount of transmitted power and increases the reactive power consumption in the transmission line. Since the SSSC is a series-connected flexible AC transmission system (FACTS) device, it has two points of connection (two terminals) with the transmission line per phase. In this paper, a control system for the SSSC is proposed to control the voltage at one terminal of the SSSC output terminals to maintain the voltage at the point of connection of the wind farm and the grid. Digital simulations of a small wind farm, using HYPERSIM, are used to determine the feasibility of the proposed control system of the SSSC.
