Damping of low-frequency electro-mechanical oscillation is very important for the system secure operation. The fast acting, FACTS device which is capable of improving both steady state and dynamic performance permit newer opproaches to system stabilization. In this paper, presents a novel approach for designing of damping controller for STATCOM in order to enhance the damping of power system low frequency oscillations(LFO). Based on Phillips-heffron model linearization, problem of damping controller design considered as an optimizing problem of multi purpose with criterion function and it is solved with utilizing honey bee mating optimization algotithm. To validate the accuracy of results a comparison with GA has been made. This controller is designed in order to transmit unstable electromechanical modes to specific area of complex plane. The proposed controller performance is confirmed by analysis of eigenvalue and nonlinear time-domain simulation under various disturbances with both control parameter of STATCOM( capacitor voltage control and terminal voltage control). Simulation results illustrate that design of controller based of capacitor voltage control in comparison with terminal voltage control has better low frequency oscillation damping and it increases dynamical stability of power system.
