AN EXPERIMENTAL DEVICE FOR DYNAMIC SIMULATION OF THYRISTOR CONTROLLED SERIES COMPENSATION

The authors present a set of experimental device for the dynamic simulation of thyristor controlled series compensation (TCSC), in which the components of TCSC are modularized and can be flexibly combined, in addition, the structural parameters of TCSC can be regulated according to the requirement of the simulation experiment. Hierarchical structure is applied to the controller of TCSC and the controllers in different layers perform different control objectives, so the research on various control strategies can be conveniently conducted. The results of dynamic simulation show that by means of appropriate control strategy the impedance can be rapidly adjusted by the presented experimental device, the low frequency oscillation can be well suppressed and the switching over among different impedance modes, e.g., the inductive and capacitive modes, can be flexibly implemented.
