Abstract :
This paper presents a nonlinear controller for GTO based static compensators (STATCOM). This controller permits achievement of high transient performances for this kind of compensator. The design of the control system is based upon the differential algebra theory. Such a control system enables global stabilization of the compensation system and thus helps to improve largely the transient performance of the global system. The system is simulated using the averaged model for inverters in order to validate the controller performance
