Improved coordinated control for thyristor controlled series compensation and generator excitation

This article improves the coordinated passivation control strategy of a single machine infinite bus system with generator excitation and thyristor controlled series compensation. First, in traditional strategy, class − κ functions an integral term are introduced to improve convergence speed reduce steady-state error system. Furthermore, adaptive method based on sliding mode is used design laws for uncertain parameters external disturbances simplify controller form. Finally, simulation results show that compared method, proposed has stronger robust adaptability rate transient performance
