One of the most important functions of Static Synchronous Series Compensator (SSSC)is power oscillation damping system. Consider the change process of SSSC internal dynamics, namely the controller’s output voltage amplitude,phase angle changes and the DC side capacitor dynamic adjustment process, the establishment of SSSC dynamic model based on this. Pulse width modulation coefficient derivation of the relationship with the amount of change in the electrical angular velocity variation between the control system transfer function obtained by controlling the parameters of the control system and thus SSSC controls and parameter control systems by artificial bee colony (ABC) the optimization process of adjustment. The optimization method with angular velocity difference as the goal, through continuous iterative update, and finally get the optimal solution control system parameters. Built in Matlab model, with the conventional PI control simulation results were compared, it can effectively and quickly adjust control parameters optimization methods to better regulate the SSSC equivalent injection voltage, effectively improve the active transmission line transmission capacity, fast power oscillation suppression system.
